Description
S23 10 mg Astera Labs — Backed by a rigorous commitment to quality, s-23 is the most potent SARM currently available, approaching anabolic steroid-level results. It produces dramatic lean mass gains, significant strength increases, and notable muscle hardening. Due to its potency, S-23 causes substantial testosterone suppression and requires full PCT. This formulation is dosed at 10 mg per unit.
Key Benefits
- High-potency SARM — full agonist AR profile
- Strong mass-building effect at 10–30 mg/day
- Meaningful HPTA suppression — full PCT required
- Oral once-daily dosing
- More androgenic sides than Ostarine — hair/skin effects possible
- Each unit dosed at 10 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 10–30 mg/day single morning dose. Cycles 8 weeks. Above 30 mg/day HPTA suppression becomes severe.
How It Works
High-potency SARM with full agonist activity at the AR. Stronger than Ligandrol; feels like a low-dose oral AAS. Developed originally as a male contraceptive candidate due to potent spermatogenic suppression.
Pharmacokinetics
Plasma half-life approximately 12 hours. Once or twice daily dosing. Oral bioavailability good.
Potential Side Effects
HPTA suppression severe at 20+ mg/day. Hair-thinning in predisposed users. HDL drops. Aggression and mood volatility. Full PCT (Nolva + Clomid × 4 weeks) mandatory.
Cycle & Stacking Guide
8-week cycles at 10–20 mg/day. Full PCT. Not a beginner SARM. Stacks with Ostarine or cardarine for cutting-recomp if aggressive results are the goal.
