Description
Bayexan (Primobol) 100 mg AdamLabs — Methenolone represents the thinking athlete’s steroid: lower risk, slower but sustainable progress, and gains that are kept post-cycle. While it won’t produce the dramatic overnight results of harsher compounds, the quality and permanence of its effects are unmatched. This formulation is dosed at 100 mg per unit.
Key Benefits
- Very mild anabolic — the cleanest injectable AAS
- No aromatisation, no progestagenic activity
- Low suppression — recoverable HPTA with minimal PCT
- Historically the “bodybuilder’s favourite” for cutting
- Expensive — underdosed on grey market more than any other compound
- Each unit dosed at 100 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 400–700 mg/week. Primo is mild — underdosed vials below 400 mg/week show almost no effect. Cycles 12–14 weeks common. Double the typical testosterone dose to see proportional results.
How It Works
Methenolone enanthate. 5α-reduced, no aromatisation, no progestagenic activity. Weakly binds the AR — anabolic benefit comes partly from nitrogen retention and partly from mild anti-catabolic effects during caloric deficits.
Pharmacokinetics
Plasma half-life approximately 10 days (enanthate ester). Weekly or twice-weekly pinning. Slow saturation — front-load first week at 800+ mg to speed it up. Clears in 3 weeks post-last-pin.
Cycle & Stacking Guide
Cutting recomp 12–14 weeks. Pair with test E 300–500 mg/week + primo 500–600 mg/week for clean, dry gains. Popular cycle finisher. Underdosed product is the main risk — source matters.
