Test Isocaproate

VGL Fitness Test Iso 100, a standalone Testosterone Isocaproate dosed at 100mg/ml for those seeking smooth, long-lasting testosterone release without the volatility of shorter esters. Typically found in blends like Sustanon, Test Iso 100 offers a stable hormonal curve, making it perfect for users who prefer fewer injections per week while maintaining consistent levels, with its clean release profile and strong anabolic support.
