Andarine (S4) 25
$85.00
Iron Ascension Andarine (S4) 25 is a potent selective androgen receptor modulator engineered to drive rapid lean muscle retention, enhanced muscular hardness, and targeted body recomposition. By selectively binding to androgen receptors in skeletal muscle and bone, it promotes anabolic activity and accelerated lipolysis without causing subcutaneous water retention or estrogenic conversion, making it ideal for cutting and recomp protocols.

Description
Iron Ascension Andarine (S4) 25
Specifications & Composition
| Specification | Details |
|---|---|
| Active Compound | S-4 (Andarine), an investigational selective androgen receptor modulator (SARM) |
| Concentration | 25 mg per tablet |
| Total Quantity | 60 tablets |
| Delivery System | Oral administration |
| Formulation Standard | Pharmaceutical grade — manufacturer claim, not independently verified |
| Batch Testing | High-Performance Liquid Chromatography (HPLC) |
Key Pharmacological Features
- Androgen receptor activity: Andarine has been investigated for selective androgen receptor activity in muscle and bone tissue. Its effects and selectivity in humans are not sufficiently established to support claims of reliable lean-mass preservation or muscle growth.
- Body composition: Claims of eliminating fluid retention, producing a consistently dry appearance, or accelerating fat loss are not established clinical outcomes.
- Bone and physical performance: Preclinical research has explored possible effects on bone and muscle. Reliable human evidence supporting improved bone mineral density, strength, or athletic performance is lacking.
Safety & Clinical Considerations
Andarine is an investigational compound and is not an approved medicine for bodybuilding or performance enhancement. Human safety data are limited. A notable concern is visual disturbance, including changes in color perception and difficulty adapting to darkness. Other potential concerns include hormonal suppression, adverse lipid changes, and unknown long-term effects.
Quality Control & Lab Verification
The manufacturer reports the following batch result:
| Quality Parameter | Reported Result |
|---|---|
| Compound | S-4 (Andarine) — oral tablets |
| Assay Result | 99.7% active compound |
| Testing Method | HPLC — confirm against the batch-specific laboratory report |
| Verification Status | PASSED — manufacturer-reported |
Publication note: Verify the chemical identity, 25 mg tablet content, 99.7% assay result, and pharmaceutical-grade designation against a genuine, batch-specific certificate of analysis. HPLC assay alone does not establish tablet uniformity, dissolution, contaminant absence, or clinical safety. Andarine remains investigational; a reported assay result is not evidence of human efficacy or suitability for consumption.
