Mastorine (S23) is a highly potent Selective Androgen Receptor Modulator (SARM) known for strong anabolic activity and a “dry”, dense look in physique-oriented use. S23 is often associated with increases in strength, muscle hardness, and overall body recomposition (muscle retention/gain with fat reduction), making it popular among advanced users looking for a more aggressive SARM profile than mild compounds.

$92.00
Description
S23 works by binding to androgen receptors in muscle tissue, stimulating anabolic signaling. Compared to milder SARMs, S23 is commonly described as more suppressive, which is why recovery and monitoring are typically emphasized.
Product dosage: 10 mg per capsule.
Recommended dosage: 10–20 mg per day
Suitable for most users, it provides significant gains in strength, muscle hardness, and fat loss.
Maximum dosage: Up to 30 mg per day
Used by experienced athletes, but increases the risk of natural testosterone suppression.
When to take:
- Once daily, as S23 has a long duration of action.
- Can be taken in the morning or 30–60 minutes before training if the goal is to enhance training performance.
How long to take:
- 6–8 weeks is the optimal cycle length.
- After the cycle, it is recommended to take a break of at least 4 weeks and perform a mandatory post-cycle testosterone test (PCT), as S23 significantly suppresses natural testosterone.
