Description
S4 (Andarine) 10 mg Elbrus Pharmaceuticals — Precision-dosed for consistent results, an early-generation SARM developed for treatment of muscle wasting and osteoporosis. It provides moderate muscle-building effects with notable fat loss and hardening properties. Andarine is valued for producing a lean, hard, dry physique similar to Winstrol but with SARM-level side effect mitigation. This formulation is dosed at 10 mg per unit.
Key Benefits
- S-4 SARM — selective androgen receptor activation with partial profile
- Effective at body-recomposition dosing
- Distinct visual side-effect (yellow tinge) from ocular-pigment binding
- Oral once or twice daily
- Mild HPTA suppression — mini-PCT advisable
- Each unit dosed at 10 mg — see Recommended Dosage below for protocol-specific intake
Recommended Dosage
Research dosing: 25–50 mg/day split twice daily for 6–8 weeks. Split dosing smooths plasma. Above 50 mg/day the visual side-effect (yellow tinge / night-vision impairment) amplifies.
How It Works
Selective androgen receptor modulator with partial agonism profile. Tissue-selective effect on muscle and bone with minimal prostate/skin impact. Downstream anabolic signal milder than full-potency SARMs (ligandrol, RAD-140).
Pharmacokinetics
Plasma half-life approximately 4 hours — twice-daily dosing required. Oral bioavailability reasonable. Reconstituted oil or powder stable at room temperature.
Potential Side Effects
Signature visual disturbance: yellowing tint to vision, especially in low light. Resolves within 1–2 weeks of discontinuation. Mild HPTA suppression. HDL drops slightly.
Cycle & Stacking Guide
6–8 week cycles, 25–50 mg/day. Mini-PCT (Nolva 20 mg × 3 weeks) after 8-week runs. Often stacked with Ostarine or cardarine for cutting protocols.
Manufacturer Notes
Elbrus Pharmaceuticals is an Eastern European producer with GMP certification. Their pharmacology catalogue is broad, covering AAS, peptides, and harm-reduction supports.
Storage & Handling
Store at recommended temperature (15–25°C; peptides and HGH at 2–8°C after reconstitution). Protect from light and moisture. Keep out of reach of children. For research and educational purposes only.
