🧪 Product Overview
SUSTAGEN 250 is a four-ester testosterone blend (propionate, phenylpropionate, isocaproate, and decanoate), delivering both rapid onset and sustained androgen activity.
Its multi-ester design produces an initial spike within 24 hours, followed by longer-lasting serum levels for up to ~3 weeks, making it ideal for short-to-medium-term hormone research, lean muscle growth studies, and strength development protocols.
Each carton contains 10 × 1 ml GMP-aligned sterile ampoules, providing 2,500 mg total active compound (250 mg/ml × 10 ml) with a 36-month shelf-life.
