What is Methenolone Enanthate?

Methenolone is a synthetic anabolic-androgenic steroid derived from dihydrotestosterone (DHT), first marketed in the 1960s under the Primobolan brand for clinical use in muscle wasting, premature infants and aplastic anaemia. The enanthate ester slows release after intramuscular injection, giving an active half-life of roughly 10.5 days — long enough that once- or twice-weekly injections maintain stable blood levels through a cycle. Because methenolone is DHT-derived it cannot aromatise to estrogen, so it produces no gynecomastia risk, no water retention and no requirement for an aromatase inhibitor. It is also one of the few injectable AAS with no 17-alpha-alkylation, meaning effectively no hepatic load. Primobolan is widely cited as the mildest mainstream injectable steroid, but mildness is paired with modest potency — gains are slow, dry and quality-led rather than dramatic.

Primobolan Depot 100 benefits

• Lean, dry muscle gains with no bloat or water weight
• No aromatisation — no estrogen-related side effects, no AI required
• No measurable hepatotoxicity (non-17aa injectable)
• Mild on lipids and blood pressure compared with most injectables
• One of the few AAS genuinely tolerated by women at low doses

The standard 100 mg/ml strength suits users who prefer predictable, fractional dosing — 4–8 ml per week splits cleanly into two injections, which keeps each shot volume comfortable.

Primobolan Depot 100 dosage and cycle

Beginners: 400 mg/wk. Intermediate: 500–600 mg/wk. Advanced: 700–800 mg/wk. Women: 50–100 mg/wk only, in short 6–8 week cycles. Cycle length typically runs 10–12 weeks because methenolone is a slow, gradual compound — onset is at roughly 3–4 weeks and the visible payoff arrives later than with most steroids. Most users split the weekly dose into two intramuscular injections (Monday/Thursday) to keep blood levels steady. Patience is part of the protocol with this compound.

Side effects and PCT

Primobolan is mild but not side-effect free. Possible effects include mild acne in susceptible users, mild androgenic effects (hair thinning in genetically predisposed men, mild virilisation in women if doses or cycle length are pushed), and partial HPTA suppression that requires post-cycle therapy. Lipid impact is real but modest. There is no aromatisation, so no aromatase inhibitor is required, and no 17-alpha-alkylation, so liver-support is unnecessary at sensible doses. After the cycle, a standard PCT with PCT Tabs Pharmaqo is recommended to restore endogenous testosterone production. A testosterone base is strongly advised on any Primobolan cycle for men — running it solo tends to leave libido flat.

Stacks well with

For a clean cutting cycle, many users combine Primobolan Depot 100 with Masteron Enanthate for a hard, dry physique, or run Test E 300 alongside as the testosterone base to maintain libido and recovery.

Frequently asked questions

How long does Primobolan Depot 100 take to start working?

Onset is gradual. Most users notice subtle recomposition and harder-looking muscle from week 3 to 4, with the bulk of visible payoff arriving in weeks 6 to 10. Primobolan is a slow, quality-led compound — patience is part of the protocol, which is why cycles typically run 10–12 weeks rather than the 6–8 weeks common with harsher steroids.

Is Primobolan Depot 100 suitable for first-time users?

It is one of the milder injectable AAS and is well tolerated, but the slow onset and modest payoff make it a poor solo first cycle for men — it is usually better paired with a testosterone base such as Test E. For women, Primobolan is one of the few injectable steroids that can be used at low dose with low virilisation risk, making it a popular choice for female athletes.

Can Primobolan be detected on a drug test?

Yes. Methenolone metabolites are detectable in urine for approximately 5 weeks after the last dose with standard WADA-grade GC-MS testing. Real-world detection windows vary by lab sensitivity, so anyone subject to sport or workplace drug testing should plan accordingly — long-ester injectables generally produce longer detection windows than orals.
