HGH vs MENT
FDA Approved vs Emerging
synergistic Mechanism-based · 49% MENT helps manage estrogen conversion from HGH. This is a common and recommended combination. Adjust AI dose based on bloodwork — avoid crashing estrogen.
Molecular Data
HGH MENT
Weight 22,124 Da 288.43 Da
Half-life 3-4 hours (SC), 20-30 minutes (IV) ~40 minutes (acetate ester)
Chain 191 amino acids —
Type Single-chain polypeptide with two disulfide bridges 7-alpha-methyl-19-nortestosterone (C19H28O2)
Key Benefits
HGH
01 Improved body composition (increased lean mass, decreased fat)
02 Enhanced bone mineral density
03 Improved lipid profile
04 Increased exercise capacity
05 Better quality of life and mood
06 Skin, hair, and nail improvements
07 Enhanced recovery and healing
MENT
01 Approximately 10x more potent than testosterone, allowing effective results at very low doses (5-25 mg/day)
02 Does not cause the sexual dysfunction associated with other 19-nor compounds like nandrolone
03 Can potentially serve as a standalone base, replacing testosterone in hormone replacement protocols
04 Rapid clearance of the acetate ester allows quick dose adjustments and fast resolution of side effects upon discontinuation
05 Powerful lean mass accretion and strength gains relative to dose
06 Under investigation as a reversible male hormonal contraceptive
07 Resistance to 5-alpha reductase means it does not convert to DHT, potentially sparing hair follicles from direct DHT-mediated damage
08 Robust suppression of gonadotropins (LH/FSH), which is therapeutically useful in contraceptive applications
Dosing Protocols
HGH
1-4 IU daily (0.33-1.33mg); start low and titrate up / Once daily or split into 2 doses (morning and evening)
Medical GHD (Starting) 0.15-0.3mg/day (0.5-1 IU) Once daily
Medical GHD (Maintenance) 0.4-0.8mg/day (1.2-2.4 IU) Once daily
Anti-Aging/Wellness 1-2 IU/day (0.33-0.67mg) Once daily
Body Recomposition 2-4 IU/day (0.67-1.33mg) Once or twice daily
Performance (Higher Risk) 4-8 IU/day (1.33-2.67mg) Split twice daily
MENT
5-25 mg/day (acetate) / Daily or split into 2x daily (acetate ester)
TRT Replacement - Low Dose 5-10 mg/day Daily (or split into 2 injections per day)
Moderate Anabolic Protocol 10-15 mg/day Split into 2 injections per day
Higher Dose - Advanced 15-25 mg/day Split into 2 injections per day
Side Effects
HGH
Water retention and fluid accumulation
Joint pain and stiffness
Carpal tunnel syndrome (usually resolves with dose reduction)
Headaches
Numbness/tingling in hands
MENT
Estrogen management difficulty -- 7-alpha-methyl-estradiol is harder to control with conventional aromatase inhibitors
Water retention and bloating, particularly at doses above 10 mg/day
Elevated blood pressure, often linked to water retention and estrogenic load
Mood changes including irritability, emotional sensitivity, or anxiety (frequently estrogen-related)
Profoundly suppressive of the HPG axis -- LH and FSH driven to near-zero even at low doses
Injection frequency burden (daily or twice-daily with acetate ester)
Mild acne and oily skin
Increased appetite
Contraindications
Active cancer (may accelerate tumor growth)
Acute critical illness (increased mortality in ICU patients)
Closed epiphyses in children (for growth promotion)
Pregnancy/breastfeeding
Prostate cancer (active or history of hormone-sensitive prostate cancer)
Breast cancer in males or females
Pregnancy or potential for pregnancy
Severe hepatic impairment
Polycythemia (hematocrit above 54% at baseline)
Uncontrolled hypertension or severe cardiovascular disease
Uncontrolled heart failure
Known hypersensitivity to trestolone or any formulation components
