MASTERBOL-P from Supreme Pharmaceuticals contains 100 mg/ml of Drostanolone Propionate, a short-acting anabolic steroid favored for its powerful hardening and anti-estrogenic effects. Often used in the final weeks before competitions, MASTERBOL-P helps athletes achieve a lean, dry, and vascular physique. It enhances muscle definition, reduces subcutaneous water retention, and does not aromatize into estrogen. This makes it a preferred choice during cutting phases or when muscle quality and aesthetic appearance are priorities. Due to its short ester, it requires more frequent injections for stable levels.
