DragonPharma.Net is a verified distributor of Dragon Pharma SARMs. We offer authentic S 23 (Mastorin) 10 mg tablets with fast USA domestic (2–5 days) and international (7–21 days) shipping. Backed by lab-tested purity, this SARM is ideal for advanced users targeting extreme definition and strength.
S 23, also known as Mastorin, is a selective androgen receptor modulator (SARM) designed to bind with high affinity to androgen receptors in muscle and bone. It's particularly known for promoting muscle hardness, vascularity, and fat loss—making it a popular choice during cutting phases or pre-contest preparation. Compared to other SARMs like Ostarine (MK 2866) or Ligandrol (LGD 4033), S 23 is significantly more suppressive and potent.
Most users cycle S 23 at 10–20 mg/day for 6 to 8 weeks. Due to its half-life (~12 hours), split dosing may help maintain more stable blood levels. It is commonly stacked with other SARMs such as Cardarine (GW501516) for enhanced endurance and fat loss synergy. Because of its powerful binding affinity, this compound is best suited for experienced users.
S 23 is non-aromatizing, so there is no water retention or gynecomastia risk. However, its strong androgenic nature means virilization in women is highly likely—this compound is not recommended for female use.
Following a cycle of S 23, post-cycle therapy is essential. We recommend starting Clomid (50 mg/day) or Nolvadex (20 mg/day) for 4 weeks to restore natural testosterone production. Visit our Post-Cycle Therapy category for additional hormonal recovery options.
Week | S 23 | Optional Add-ons |
---|---|---|
1–4 | 10–20 mg/day | GW501516 (10–20 mg/day) |
5–8 | 10–20 mg/day | Continue support or add LIV 52 |
9–12 | PCT | Clomid / Nolvadex |
