SUSTANON 250
10 x 1ml sterile ampoules · Injectable research solution
Price: 49 €
SUSTANON 250 (often compared to Sustanon 250) blends four mixed testosterone esters — propionate, phenylpropionate, isocaproate and decanoate — to give researchers both a rapid spike and a sustained plateau of serum androgen activity. The profile is prized in studies that aim to boost testosterone levels, map lean muscle growth signalling and examine muscle strength over acute-to-chronic time-courses. Esterification length modulates release kinetics: propionate peaks within 24 h, while decanoate maintains elevations for ~ 3 weeks, letting a single preparation support short- and medium-term hormone-replacement models.

🧪 Product Overview
Sustanon 250 is a multi-ester testosterone blend designed for research on muscle recovery, androgen receptor activity, and endocrine feedback.
Each 10 ml vial contains 2,500 mg total testosterone esters (250 mg/ml × 10 ml) in a GMP-aligned sterile fill, ensuring 36-month shelf-life.
The four-ester formula combines immediate, mid-range, and long-acting release profiles, creating a stepwise androgen exposure curve ideal for extended in-vitro or preclinical studies.
