Description
Mastabol 100 mg British Dragon Pharmaceuticals — Drostanolone occupies a unique position among injectable steroids: it functions simultaneously as a potent hardening agent and a mild aromatase inhibitor. This dual action produces a dry, chiseled appearance while actively reducing estrogen-mediated water retention and fat storage. This formulation is dosed at 100 mg per unit.
Key Benefits
- DHT-derivative — dry, hard, vascular look with no water retention
- Anti-estrogenic side-activity — mild AI effect
- Cutting and pre-contest staple, especially at low body-fat
- Minimal sides at performance doses — clean compound
- Stacks well with tren, test, and orals for cutting recomp
- Each unit dosed at 100 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: propionate 300–500 mg/week split EOD or 3×/week; enanthate 400–600 mg/week split twice weekly. Cycles 8–10 weeks (prop) or 10–14 weeks (eno). Pre-contest protocols stretch to final 6 weeks before show.
How It Works
5α-reduced testosterone with a 2α-methyl group. DHT-derivative — does not aromatise. Mild anti-estrogenic activity via aromatase enzyme competition. High AR affinity. Androgenic but not aggressively so at typical doses.
Pharmacokinetics
Propionate ester: plasma half-life ~2 days. Enanthate: ~7 days. Prop needs EOD or M/W/F pinning; eno twice-weekly fine. Steady-state in 2 weeks (prop) or 4 weeks (eno).
Potential Side Effects
Hair-thinning risk for genetically predisposed users — the DHT-derived nature makes it unfriendly to MPB. Oestrogenic sides absent. HDL drops moderately. Mild HPTA suppression recoverable with standard PCT.
Cycle & Stacking Guide
Cutting stack component, 8–14 weeks by ester. Classic pairing: test E 250 mg/week + masteron E 400 mg/week + (optional) tren or winstrol for final weeks. Works best at <15% body fat where the "dry" look actually shows.
