Description
This Bayer proviron at 25 mg delivers an anti-estrogenic edge (mild aromatase inhibition) plus SHBG displacement. Safe across long cycles; minimal HPTA impact.
Key Benefits
- DHT-class oral — SHBG reducer and libido support
- Mild anti-estrogen by AR competition at the breast tissue
- Does not suppress HPTA at typical doses — can be run year-round
- No aromatisation, minimal liver load despite 17α-methylation
- On-cycle auxiliary, not a mass-builder
- Each unit dosed at 25 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 25–75 mg/day, split 2–3×. Cycle with compounds that benefit from reduced SHBG (testosterone-based stacks). Can run for full cycle duration (12+ weeks) due to mild profile.
How It Works
17α-methyl DHT (proviron). Binds the AR weakly but has high SHBG affinity — the primary on-cycle benefit is freeing bound testosterone. Does not aromatise. Mild anti-estrogenic effect via AR competition in breast tissue. Androgenic but not mass-building.
Pharmacokinetics
Plasma half-life approximately 12 hours. Twice-daily dosing smooths serum. Hepatotoxic profile milder than most 17α-methylated orals — ALT/AST at week 6 still standard.
Potential Side Effects
Signature improvements: libido restoration on cycle, denser muscle feel. Side-effect profile mild. Hair-thinning risk in susceptible users. Minimal HPTA impact — not a PCT compound, but not a suppressant either.
Cycle & Stacking Guide
Run alongside any testosterone-based cycle at 25–50 mg/day for on-cycle libido and SHBG management. Stacks with cutting protocols (test + mesterolone + clen/var) for harder look. Not a standalone compound.
Manufacturer Notes

Storage & Handling
Store in the original blister or bottle at 15–25 °C, away from direct sunlight, heat, and humidity. Oral preparations lose potency faster if exposed to moisture; keep the desiccant (if included) with the tablets. Keep out of reach of children. For research and educational purposes only.
