Description

Ostarine (MK-2866) 25mg — ostarine (MK-2866) from the manufacturer at 25 mg. Selective androgen receptor modulator — tissue-targeted for muscle and bone. Milder HPTA suppression than anabolic steroids.

Key Benefits

  • Most-studied SARM — extensive clinical trial data
  • Low suppression at 10–15 mg/day — recovery often possible without PCT
  • Cutting recomp compound — lean mass in caloric deficit
  • Oral once-daily dosing
  • Starting compound for SARM-curious users
  • Each unit dosed at 25 mg — see Recommended Dosage below for protocol-specific intake

Recommended Dosage

Research dosing: 10–25 mg/day for 8 weeks. Women 5–10 mg/day. Single daily dose adequate given long half-life. Cycles 8–12 weeks. Doses above 25 mg/day suppression becomes meaningful.

How It Works

MK-2866, selective androgen receptor modulator. Binds the AR with tissue selectivity: high activity in muscle and bone, low activity in prostate and skin. Downstream anabolic effects without the full androgenic profile of AAS.

Pharmacokinetics

Plasma half-life approximately 24 hours. Once-daily dosing sufficient. Steady-state in 5 days.

Cycle & Stacking Guide

Beginner SARM cycle: 10–15 mg/day × 8 weeks. Mild mini-PCT (Nolva 20 mg/day × 4 weeks) if bloodwork confirms suppression. Stacks with cardarine for recomp or with TRT for lean gains.

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.
