Since the Centrino Primobolan tablets are not I 7-alpha alkylated but have a 17-beta hydroxy group they are almost non-toxic to the liver. In a high dosage, however, they can influence the liver values resulting in higher biliburin, GPT, GOT, and alkaline phosphatase. Primobolan generally does not cause any significant side effects since it does not aromatize, does not cause water retention, is not I 7-alpha alkylated, and is only slightly androgenic. Blood pressure, liver values, cholesterol level, HDL and LDL values usually remain unaffected, making Primobolan well liked by health-conscious older athletes. Primo is often an “entry drug” for novice users and, due to its rare side effects, encourages many steroid users to switch to “harder” stuff such as Dianabol, Anadrol 50, and testosterone. Since Primobolan is a precursor of dihydrotestosterone it can accelerate hair loss if such a predisposition exists.
