The ester of this compound makes it slow acting, and thus means that injections can be less frequent. Bodybuilders using this steroid often follow a dosage schedule of two-three shots per week.
Primobolan Depot, as it is often called, is a very popular steroid amongst bodybuilders who are in the “cutting” phase of their training and dieting. This steroid is very mild in its nature and seems to work exceptionally well with calorie restricted diets.
Primobolan Depot will not aromatize in the body, therefore estrogenic side effects such as bloat should not be a concern. Bodybuilders with reasonably low bodyfat will notice an increase in definition and lean muscle mass.
This steroid was reportedly a long time favorite of the great Arnold Schwarzenagger. Many attribute Arnold’s use of this drug to his ability to keep such a small waist and aesthetic looking physique. Primobolan Depot is also a very popular “bridging” steroid, meaning that bodybuilders sometimes use a steady dose of it in between their regular cycles to keep the body in a more anabolic state that natural, but while not keeping natural testosterone shut down as harshly as some other steroids will do.
Those looking to use Primobolan Depot in a cycle might stack it with a low dose of a Testosterone and an oral such as Winstrol or Anavar. Primobolan Depot is also a very popular steroid with women bodybuilders where it’s low androgenic properties and mild nature makes it a very safe choice for them to use. Male bodybuilders often use Primobolan Depot in a dose of 200-400mgs a week, anywhere from 8-16wks.
The effect of Primobolan (methenolone enanthate; 10 mg kg −1 thrice-weekly) on total body nitrogen, potassium, phosphorus, and body-weight, muscle protein synthesis and food conversion efficiency was measured in Wistar rats during the period from weanling to maturity (22 to 64 days of age). Treated male rats exhibited a lower rate of weight gain, increased kidney weight and decreased testicular weight when compared with controls. No differences in total nitrogen, potassium or phosphorus were observed. Treated female rats had significantly increased body-weight, total body nitrogen, phosphorus, and potassium compared with female controls although, when expressed as a percentage of body weight, phosphorus content was higher in controls. Treated female rats had increased food conversion efficiency expressed relative to total body weight gain or total body nitrogen gain. Rates of synthesis of mixed skeletal muscle protein, measured at the conclusion of the study, indicated that treated females had a significantly increased rate of synthesis when compared to female controls. There was no significant difference between treated male rats and control animals.
