Description
Drostanolone (Masteron), Utinon, 100 mg. DHT-class anti-estrogenic anabolic with minimal side-effect burden relative to its visual impact. Low-bodyfat cutting staple; Propionate for EOD schedules, Enanthate for 2×-weekly flexibility.
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.
Manufacturer Notes
Utinon is an Iranian GMP producer with decades of domestic pharmaceutical experience. The catalogue features both injectable and oral formats.
Storage & Handling
Store upright at 15–25 °C in the original box, protected from light and moisture. Oil-based injectables are shelf-stable for the duration printed on the vial when kept at controlled room temperature. Do not refrigerate — cold thickens the carrier oil and makes drawing/injecting harder. Keep out of reach of children. For research and educational purposes only.
