Side effects

Testosterone is the primary male androgen, so pronounced androgenic side effects such as increased sebum secretion, acne, body and facial hair growth, and male pattern baldness can be expected.

Like all forms of testosterone, Testosterone Cypionate converts to estrogen. This causes water retention in the muscles, which can cause roll back syndrome after the cycle (up to 30% of muscle mass can be lost).

It is necessary to add an anti-estrogen to your cycle, preferably an aromatase inhibitor, to avoid side effects such as gynecomastia, water retention, fat deposition and decreased testosterone production.
