🧪 Product Overview
Primobolan 25 mg offers researchers an oral DHT-derived anabolic compound with exceptionally low androgenic and hepatic burden. Known scientifically as methenolone acetate, it is widely used in lean-mass preservation, catabolic-state models, and nitrogen-balance studies.
The acetate ester gives Primobolan a short oral half-life (~3–5 hours), requiring twice-daily dosing for stable plasma levels. Its minimal aromatisation, mild androgenicity, and long detection window (>10 days via LC-MS/MS) make it a key substance in cutting-phase protocols and anti-doping method development.
✅ Key Research Highlights
Mild androgenic profile: In vitro studies show myotrophic potency exceeding testosterone, yet lower androgenic signaling
Short half-life (oral): 3–5 hours; plasma levels best sustained by ≥2 daily doses
Liver safety: Absence of 17-α-methyl group significantly reduces hepatotoxic risk
Minimal aromatisation: Estrogen conversion is virtually absent, reducing gynecomastia risk
Nitrogen retention: Clinical data confirms reduced urinary nitrogen loss in muscle-wasting states
Anti-doping classification: Long-term urinary metabolites allow detection >10 days post-exposure (WADA S1 listed)
