⚠️ IMPORTANT MEDICAL WARNING
This material is for educational purposes only and is not medical advice, prescription, or guidance for action.
Hormone Replacement Therapy (HRT/TRT) is a serious medical intervention that should only be conducted under the supervision of a qualified endocrinologist or urologist-andrologist.
What you should understand:
- Self-treatment with hormones is dangerous — incorrect dosages, lack of monitoring, and ignoring contraindications can lead to serious health consequences.
- Before starting any therapy, you need:
- Complete medical examination
- Hormonal profile tests
- Exclusion of contraindications
- Individual protocol selection
- Testosterone is a controlled substance in most countries. Its purchase, storage, and use without a prescription may be illegal.

HRT as a Biohacking Tool
Why Biohackers Turn to HRT
Testosterone Replacement Therapy (TRT) is one of the most studied and effective tools for optimizing male health. In the biohacking context, the goal of TRT is not achieving supraphysiological levels (as in bodybuilding), but restoring optimal physiological values.
Biohacking ≠ Bodybuilding
| Aspect | Biohacking | Bodybuilding |
|---|---|---|
| Goal | Optimal health | Maximum muscle mass |
| Dosages | Physiological (100-200 mg/week) | Supraphysiological (500+ mg/week) |
| Monitoring | Regular, comprehensive | Often minimal |
| Duration | Long-term therapy | Cycles |
| Risk approach | Minimization | Often ignored |
Key TRT Goals in Biohacking
- Energy and cognitive function — optimal testosterone correlates with mental clarity and productivity
- Body composition — maintaining muscle mass, fat control
- Libido and sexual function — one of the most noticeable therapy effects
- Mood and motivation — stable levels reduce depression risk
- Cardiometabolic health — properly selected therapy can improve lipid profile
When to Consider TRT
Indications for examination:
- Deficiency symptoms (fatigue, decreased libido, cognitive fog)
- Laboratory-confirmed low testosterone (< 300-350 ng/dL)
- Age 30+ with progressive decline
- No effect from lifestyle interventions
Testosterone Basics
Testosterone Physiology
Testosterone is the primary male sex hormone, key to many body functions.
Where It's Produced
- 95% — testes (Leydig cells)
- 5% — adrenal glands
- In women: ovaries and adrenal glands (in smaller amounts)
Regulation: HPG Axis (Hypothalamus-Pituitary-Gonad)
```
Hypothalamus → GnRH → Pituitary → LH/FSH → Testes → Testosterone
↓
Negative feedback loop
```
- GnRH (gonadotropin-releasing hormone) — signal from hypothalamus
- LH (luteinizing hormone) — stimulates testosterone production
- FSH (follicle-stimulating hormone) — stimulates spermatogenesis
Forms of Testosterone in Blood
| Form | % of total | Function |
|---|---|---|
| SHBG-bound | 44-65% | Inactive, transport form |
| Albumin-bound | 33-54% | Weakly bound, available to tissues |
| Free | 1-3% | Biologically active |
Bioavailable testosterone = Free + Albumin-bound
Why Levels Decline
- Age — approximately -1-2% per year after 30
- Obesity — fat tissue contains aromatase (conversion to estradiol)
- Chronic stress — cortisol suppresses HPG axis
- Sleep deprivation — main production occurs during sleep
- Endocrine disruptors — plastic, pesticides, phthalates
- Chronic diseases — diabetes, metabolic syndrome
Deficiency Symptoms
Physical:
- Fatigue, decreased energy
- Loss of muscle mass
- Increased fat tissue
- Decreased libido
- Erectile dysfunction
Cognitive/Emotional:
- Brain fog
- Decreased motivation
- Irritability or apathy
- Depressive symptoms
Esters Overview
What Are Esters and Why They're Needed
Pure testosterone has a half-life of only 2-4 hours — making it impractical for therapy. Esters are chemical modifications that slow hormone release.
How Esters Work
- Injection — testosterone ester is injected into muscle or subcutaneously
- Depot — an oil depot forms at the injection site
- Release — ester gradually releases into bloodstream
- Hydrolysis — enzymes (esterases) cleave the ester group
- Active testosterone — free testosterone becomes bioavailable
Key Characteristics
- Half-life — time for concentration to decrease by half
- Injection frequency — depends on half-life
- Level stability — longer esters = more stable levels with proper frequency
- Molecular weight — affects amount of active testosterone per mg
Calculating Active Testosterone
Not all ester weight is testosterone:
| Ester | % active T | 100 mg contains |
|---|---|---|
| Propionate | 83.7% | 83.7 mg T |
| Enanthate | 72% | 72 mg T |
| Cypionate | 69.9% | 69.9 mg T |
| Undecanoate | 61.4% | 61.4 mg T |
Carrier Oils
Medications are dissolved in oil (affects tolerability):
- Sesame oil — most common
- Castor oil — used in Nebido
- Cottonseed oil — some generics
- MCT/Miglyol — faster absorption, fewer reactions
Popular Esters
Ester Comparison Table
| Ester | Half-life | Injection Freq. | Stability | Notes |
|---|---|---|---|---|
| Enanthate | 4-5 days | 1-2x/week | ★★★★☆ | TRT gold standard |
| Cypionate | 5-8 days | 1-2x/week | ★★★★☆ | Popular in USA |
| Propionate | 0.8-1 day | Daily | ★★★★★ | Fast action, frequent shots |
| Sustanon | Mixed | 1-2x/week | ★★★☆☆ | 4-ester blend |
| Undecanoate | 20-21 days | 1x/10-14 wks | ★★★☆☆ | Nebido, rare injections |
Testosterone Enanthate
TRT gold standard — most studied and widely used ester.
Characteristics
- Half-life: 4-5 days
- Peak concentration: 24-48 hours post-injection
- Recommended frequency: 1-2 times per week
Dosage
- 50-200 mg/week (or 50-100 mg 2 times per week), depending on lab results
- Subcutaneous: Many patients switch to SubQ with smaller volumes
Advantages
- Extensive evidence base
- Predictable pharmacokinetics
- Availability and cost
- Well tolerated by most
Testosterone Cypionate
Virtually identical to enanthate, dominates in USA.
Characteristics
- Half-life: 5-8 days (slightly longer than enanthate)
- Peak concentration: 24-48 hours
- Recommended frequency: 1-2 times per week
Dosage
- 50-200 mg/week (or 50-100 mg 2 times per week), depending on lab results
Differences from Enanthate
- Slightly longer half-life
- Slightly less active testosterone per mg (69.9% vs 72%)
- Interchangeable in clinical practice
Testosterone Propionate
Short-acting ester — for those wanting maximum control.
Characteristics
- Half-life: 0.8-1 day
- Peak: 4-6 hours post-injection
- Frequency: Daily injections
When Used
- Starting period (rapid effect assessment)
- Maximum stable levels
- Minimizing aromatization
Disadvantages
- Daily injections
- More frequent injection site irritation
Sustanon (Omnadren)
4-ester blend — theoretically for "smooth" levels, practically — not the best choice.
Composition (250 mg/mL)
- Propionate: 30 mg
- Phenylpropionate: 60 mg
- Isocaproate: 60 mg
- Decanoate: 100 mg
Problems
- Different half-lives create unstable curve
- Marketing product, not optimal for TRT
- Requires frequent injections for stability
Testosterone Undecanoate (Nebido)
Ultra-long ester — injections once every 10-14 weeks.
Characteristics
- Half-life: 20-21 days
- Injections: 1000 mg every 10-14 weeks
- Volume: 4 mL (intramuscular only)
Advantages
- Minimal injection frequency
- Convenience for some patients
Disadvantages
- Unstable levels (peaks and troughs)
- Large injection volume
- Harder to titrate dose
- High cost
Supporting Compounds
Compounds for TRT Optimization
In addition to testosterone itself, TRT protocols often include additional medications.
hCG (Human Chorionic Gonadotropin)
Why: Maintaining testicular function and spermatogenesis during TRT.
How It Works
- Mimics LH (luteinizing hormone) action
- Stimulates Leydig cells
- Maintains intratesticular testosterone
- Preserves testicular size
Typical Protocols
- Standard: 250-500 IU 2-3 times per week
- Minimal: 250 IU every other day
- For fertility: 500-1000 IU 3 times per week
When Necessary
- Planning fatherhood
- Concern about testicular atrophy
- Subjective feelings of "fullness"
Cautions
- May increase estradiol
- Requires E2 monitoring
- Possible desensitization at high doses
Kisspeptin
Alternative to hCG — stimulates endogenous HPG axis.
Mechanism
- Stimulates GnRH release
- More physiological approach
- Potentially better for long-term use
Status
- Being researched for TRT use
- Limited availability
- Promising alternative
Aromatase Inhibitors
Why: Controlling testosterone to estradiol conversion.
Anastrozole (Arimidex)
Most commonly used in TRT.
Indications:
- E2 > 40-50 pg/mL with symptoms
- Excess estrogen symptoms (gynecomastia, water retention)
Typical dosages:
- 0.25-0.5 mg twice weekly
- Titrated by E2 level
Important:
- DO NOT use preventively
- Too low E2 is a problem (joints, libido, mood)
- Target: 20-35 pg/mL (individual)
Alternatives
- Letrozole — more potent, rarely needed in TRT
- Exemestane — steroidal AI, irreversible
SERMs (Selective Estrogen Receptor Modulators)
Clomiphene (Clomid)
Use in TRT context:
- Monotherapy as injection alternative
- Stimulating endogenous production
- Fertility preservation
Protocol:
- 12.5-25 mg every other day or daily
- Monitoring testosterone and LH
Limitations:
- May raise E2
- Less stable T levels
- Visual side effects rare
Tamoxifen (Nolvadex)
- Used for gynecomastia
- 10-20 mg/day when needed
- Not for routine TRT use
General Principles
- Less = better — add medications only when indicated
- Monitoring — regular labs determine necessity
- Individual approach — no universal protocols
- Symptoms matter more than numbers — treat the patient, not the lab
Biomarkers & Monitoring
TRT Laboratory Monitoring
Proper monitoring is key to safe and effective therapy.
Baseline Labs Before Starting TRT
Hormone Panel

General protocol for clinician / biohacker
Biohacking Protocols
## Protocols from the Biohacking Community ⚠️ **Important**: These protocols are not official medical recommendations. They are based on biohacking community practice and require monitoring under physician supervision. ## Microdosing (Daily/EOD) ### Concept Frequent small doses for maximum level stability. ### Protocol - **Dose**: 10-20 mg daily or 20-30 mg every other day - **Total weekly**: ~100-140 mg - **Method**: Subcutaneous injections (SubQ) ### Advantages - Minimal level fluctuations - Less estradiol conversion - Stable well-being - Less AI need ### Disadvantages - Daily injections - Requires discipline - More syringe use ## SubQ (Subcutaneous Injections) ### Why SubQ Instead of IM | Aspect | SubQ | IM | |--------|------|-----| | Needle | 27-31G, 0.5" | 22-25G, 1-1.5" | | Pain | Minimal | Moderate | | Scarring | Rare | Possible | | Absorption | Slightly slower | Standard | ### Technique 1. Insulin syringe 29-31G 2. Abdomen or thigh 3. Small volumes (< 0.5 mL) 4. Injection site rotation ### Data - Studies show comparable bioavailability - Many clinics have switched to SubQ for TRT ## Creams and Gels ### Scrotal Application Applying testosterone cream to the scrotum. **Theory:** - Thin skin → better absorption - High 5α-reductase → more DHT - May improve libido and function **Protocol:** - Testosterone cream 10-20% - 50-100 mg 1-2 times daily - Applied to scrotum **Cautions:** - Elevated DHT → possible hair loss - Transfer to partners (contact) - Non-standard approach ## Combined Protocols ### Testosterone + hCG **Standard combination for fertility preservation:** - Testosterone: 100-150 mg/week - hCG: 250-500 IU 2-3 times per week ### Testosterone + Clomiphene **For maintaining endogenous function:** - Testosterone: 80-100 mg/week - Clomiphene: 12.5-25 mg every other day ## Pregnenolone and DHEA ### Pregnenolone - "Mother" hormone - May decrease during TRT - Supplement: 25-50 mg/day ### DHEA - Precursor to testosterone and estrogen - Supplement: 25-50 mg/day - Level monitoring ## Risks and Cautions ### General risks of "advanced" protocols: 1. Lack of long-term data 2. Individual variability 3. Potential unknown consequences ### Minimizing risks: - Regular monitoring (labs) - Working with competent physician - Conservative start - Documenting changes ## What Works for Most **Simple effective protocol:** 1. Testosterone enanthate/cypionate 100-150 mg/week 2. Split into 2-3 injections 3. SubQ injections 4. hCG 250-500 IU 2x/week (if fertility needed) 5. Labs every 3 months first year
These protocols are not official medical recommendations. They are based on community practice and require monitoring under medical supervision.
Frequent small doses for maximum testosterone stability and minimal estradiol fluctuations.
Typical Protocol
- 10–20 mg daily or 20–30 mg every other day, totaling ~100–140 mg/week
- Usually subcutaneous (SubQ) injections for reduced trauma and smoother pharmacokinetics
Pros
- Minimal T and E2 fluctuations
- More stable mood, energy, erections
- Reduced need for AI at moderate doses
Cons
- Daily/EOD injections
- High syringe count, schedule discipline required
- Not suitable for needle-averse patients
Why SubQ vs IM
| Aspect | SubQ | IM (intramuscular) |
|---|---|---|
| Needle | 27–31G, 0.5" | 22–25G, 1–1.5" |
| Pain | Minimal | Moderate |
| Trauma | Low | Medium–high |
| Bioavailability | Comparable | Standard |
SubQ Technique
- Insulin syringe, 29–31G
- Sites: abdomen, thigh
- Volume: <0.5 mL per injection
- Rotate sites to prevent lipodystrophy
- Inject slowly, hold needle 5–10 seconds after
Thin scrotal skin and high 5α-reductase levels may increase DHT, which some associate with improved libido and erections. But also increased risk of acne, body hair growth, and scalp hair loss.
Typical Protocol
- 10–20% testosterone cream
- 50–100 mg 1–2x/day, applied to scrotum
- Isolation, protect partner/children from contact transfer
Focus: fertility support and preventing testicular atrophy during TRT.
Typical Protocol
- Testosterone: 100–150 mg/week, usually 2x/week
- hCG: 250–500 IU 2–3x/week
- Monitor: T, E2, testicular size, libido, mood
Used when partially supporting the endogenous axis (secondary hypogonadism or mild T decline).
Typical Protocol
- Testosterone: 80–100 mg/week
- Clomiphene: 12.5–25 mg every other day or daily
- Monitor: T, LH/FSH, free T, mood, libido, E2
- Pregnenolone: 25–50 mg/day, positioned as the "mother hormone"
- DHEA: 25–50 mg/day, precursor to testosterone and estrogens
- Both can affect androgen/estrogen balance — monitoring T, E2, mood, skin and joints is mandatory
Risks
- Lack of long-term data on frequent injections, scrotal gel, combination protocols
- Strong individual variability: 20 mg/day may be comfortable for some, unstable for others
Risk Mitigation
- Regular monitoring — labs (T, E2, hematocrit, lipids, PSA) + symptom tracking
- Work with a doctor, not just forums; biohacking protocols complement medicine, not replace it
- Conservative start and gradual escalation: start low, allow 4–8 weeks to assess
Frequently Asked Questions
Short answer:
Usually yes, but not always.
What happens in practice:
- Exogenous testosterone suppresses LH and FSH, and the HPG axis "goes to sleep."
- After discontinuation, some people experience gradual recovery (from several months to a year).
- Others may not return to baseline, especially with long-term therapy and/or severe initial dysfunction.
What to do:
- Discuss exit strategy with your doctor in advance.
- If planning to stop — consider post-cycle support therapy (hCG, clomiphene, minimizing HRT duration, etc.).
Short answer:
Possibly, but not always and not necessarily permanently.
How it works:
- Exogenous T suppresses FSH → reduced or halted spermatogenesis.
- This is a reversible process in most men, but recovery may take several months.
How to reduce risk:
- hCG (250–500 IU 2–3x/week) can partially preserve or even maintain spermatogenesis.
- If planning children before starting, consider discussing:
- sperm preservation,
- possibility of using hCG/SERM combinations,
- less aggressive lifestyle/nutrition approaches that reduce the need for high T doses.
Short answer:
Possible, but not guaranteed. An individual plan is needed.
What matters:
- Age,
- Duration of therapy,
- Original cause of hypogonadism (primary or secondary).
What's realistic:
- With secondary hypogonadism (from obesity, sleep apnea, stress, hyperprolactinemia) — after eliminating the cause, partial or full recovery is common.
- With primary — chances of restoring physiological levels without exogenous T are quite low.
Typical approach:
- Gradual dose reduction,
- Monitoring 1–3 months after completion.
- If needed — using hCG, clomiphene to stimulate the axis.
Typical timeline (for adequate doses and sufficiently high initial deficiency):
- Energy and mood: 2–3 weeks.
- Libido: 2–4 weeks.
- Erectile function: 4–8 weeks.
- Body composition (muscle, fat): 3–6 months, with training and nutrition support.
- Full hormonal stabilization (T, E2, hematocrit, lipids): 3–6 months.
> Some people may experience effects faster or slower depending on dose, metabolism, psychosomatics, sleep, and stress.
Short answer:
Risk increases if you have a genetic predisposition to androgenic alopecia.
Mechanism:
- T partially converts to DHT (dihydrotestosterone) — the key factor in hair loss for predisposed individuals.
What you can do:
- Finasteride/dutasteride reduce DHT levels and can slow/stop hair loss, but may affect libido, erections, mental state.
- A gentler option — minoxidil as a topical treatment (doesn't affect hormones).
Decision:
- Discuss with a dermatologist/andrologist the risk and possible measures before starting.
- If you have strong baldness genetics, the likelihood of TRT affecting your hair is substantially higher, but it's not inevitable.
Short answer:
With proper monitoring and moderate doses — no, it doesn't increase risk; in several studies it even reduces CV events in men with deficiency; with uncontrolled self-treatment — risk increases significantly.
What research shows:
- Properly prescribed T in men with hypogonadism does not increase heart attack/stroke risk and may improve metabolic profile.
- However, inadequate use (very high doses, ignoring hematocrit, lipids, hypertension) increases risks of thrombosis and other complications.
What to do:
- Regular monitoring of hematocrit, lipids, blood pressure, ECG as indicated.
- Don't turn TRT into unmonitored "cycles" as in bodybuilding.
Short answer:
In practice and pharmacokinetics they are practically interchangeable.
What differs:
- Cypionate has a slightly longer chain, but pharmacokinetics and clinical effect are very similar.
- Cypionate dominates in the US, enanthate in Europe/parts of the EU.
How to decide:
- Base it on: availability, price, personal tolerance, doctor's recommendations.
- If you want the most stable regimen — switch to 2x/week (either ester) instead of infrequent injections.
Short answer:
Only if estradiol is elevated AND symptoms are present (breast tenderness, gynecomastia, water retention, mood swings).
What's important to understand:
- Too-low E2 is harmful for joints, bones, mood, and libido.
- Using AIs "just in case" with normal labs and no symptoms is a bad idea.
What's typically done:
- Sensitive estradiol assay,
- Initially — adjusting T dose or injection frequency,
- If needed — anastrozole at minimal doses (0.25–0.5 mg 2x/week) titrated by E2 level and symptoms.
Short answer:
TRT usually improves sleep quality in men with testosterone deficiency, but doesn't solve problems if sleep apnea, obesity, stress, etc. are present.
What often happens:
- Patients report deeper sleep, fewer awakenings, improved morning mood.
- In some people — reduced chronic fatigue associated with "hormonal exhaustion."
What's important:
- Don't expect TRT to "cure" chronic sleep deprivation and sleep apnea.
- If sleep apnea is suspected — diagnosis (polysomnography) and treatment take priority.
Short answer:
Yes, and it's even recommended.
How they interact:
- Testosterone enhances the effect of strength training:
- muscle mass growth,
- improved recovery,
- bone density support.
- Strength training, in turn, stimulates the axis and helps maintain a more natural balance.
What's recommended:
- Don't turn TRT into a "hardcore sports cycle" without monitoring.
- Track hematocrit, blood pressure, heart rate, lipids.
