Testosterone Isocaproate 200mg/mL – Bouwen
Long-acting single ester testosterone designed for steady, powerful anabolic support. Suspended in ultra-clean 60/40 MCT oil for smooth, low-irritation injections. Ideal for TRT, lean mass cycles, or as a base in advanced stacks.
Testosterone Isocaproate is a long-acting testosterone ester with a half-life of approximately 7–9 days, placing it right between Testosterone Enanthate and Testosterone Cypionate in terms of duration. Originally included in blends like Sustanon 250, Isocaproate offers the benefits of stable blood hormone levels, less frequent injections, and effective anabolic support.
Bouwen’s formulation is suspended in a clean-burning 60/40 blend of fractionated MCT oil, chosen for its low viscosity, rapid absorption, and minimized injection-site irritation. This product is produced in a sterile, small-batch environment using pharmaceutical-grade filtration protocols for maximum purity and safety.
