🧪 What is Methenolone Enanthate?
Methenolone enanthate (Primobolan) is a dihydrotestosterone (DHT)-derived anabolic steroid characterised by:
- Negligible aromatisation — does not convert to estrogen
- Lower androgenic index compared with testosterone
- Long-acting enanthate ester that extends release after I.M. injection
- Stable anabolic profile often evaluated in nitrogen-balance and lean-mass preservation models
In research contexts, methenolone is studied for its potential to preserve muscle mass, reduce catabolism and support erythropoiesis with fewer estrogen-mediated variables.
🔬 Key Compound Details
- Chemical name: 1-methyl-5α-androst-1-en-17β-ol-3-one enanthate
- Parent structure: DHT (non-aromatising)
- Pharmacological class: Esterified anabolic-androgenic steroid
- Route: Intramuscular depot
- Androgenic activity: Lower than testosterone in scaled comparisons
- Ester effect: Several-day release profile; prolonged exposure window
🧬 Mechanism of Action
After injection, the enanthate ester is slowly cleaved, releasing free methenolone which:
- Binds androgen receptors (AR) in skeletal muscle and other tissues
- Modulates transcription of androgen-responsive genes
- Promotes structural protein synthesis and nitrogen retention
- Shows reduced catabolic signalling in some research models
- Does not increase estrogenic activity, avoiding aromatase-mediated effects
These characteristics make methenolone valuable for experiments where stable anabolic action is required without confounding estrogenic variables.
📚 Research Highlights & Observations
- Lean mass preservation in catabolic states when nutrition is adequate
- Mild erythropoietic effect — increases RBC and hemoglobin in some studies
- Lower fluid retention compared with aromatising androgens
- Relatively favourable tolerability profile in historical clinical literature
These findings apply to controlled laboratory or clinical research settings only.
⚠️ Safety Profile & Possible Adverse Effects
(Based on class-wide AAS research data.)
Androgenic
- Acne, oily skin, increased body/facial hair
- Potential DHT-related scalp hair loss
- Virilisation in females (voice deepening, menstrual disruption)
Cardiovascular & Metabolic
- Reduced HDL, possible increase in LDL
- Blood pressure changes
- Elevated hematocrit via RBC stimulation
Endocrine
- Suppression of LH/FSH
- Reduced endogenous testosterone
- Impaired spermatogenesis and fertility
Hepatic
- Lower hepatotoxicity than 17α-alkylated orals, but liver enzymes may still elevate
Other
- Injection-site irritation
- Mood or behavioural changes
- Potential interactions with anticoagulants or metabolic drugs
