Testosterone cypionate is a synthetic derivative of testosterone in the form of an oil-soluble 17 (beta)-cyclopentylpropionate ester. Its benefit compared to other testosterone derivatives is the slow rate of release after injection and longer half-life. The characteristics of testosterone cypionate and testosterone enanthate are very similar, therefore both of them tend to be interchangeable.
Optimal dosage is 250-500mg/week
Injecting 2 times per week
