Description
ACP-105 5 mg Vital Research — ACP-105 from Vital Research at 5 mg. Non-steroidal SARM with tissue-selective AR agonism — potency between ostarine and ligandrol. Mild-to-moderate HPTA suppression on longer cycles.
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 5 mg — see Recommended Dosage below for protocol-specific intake
Quality Assurance
Vital Research is committed to delivering pharmaceutical-grade compounds with verified potency, purity, and sterility. Every batch undergoes rigorous third-party laboratory testing to ensure accurate dosing and absence of contaminants. With Vital Research, you receive a product backed by strict GMP manufacturing standards and complete traceability from raw material to finished product.
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
Vital Research focuses on research compounds and support supplements with batch-specific quality control documentation.
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.
