I.PRIMA (metenolone, primobolan) is a derivative of DHT, has a moderate anabolic effect and a relatively low androgenic effect, and is not aromatized. In its tablet form it is a 17-alpha-alkylated steroid, which has toxic effects on the liver.
The drug was created in the 60s of the 20th century and was started to be produced under the brand name Metenolone.
I.PRIMA is a fairly weak AS, but due to the fact that it is a derivative of DHT, it can greatly reduce hGH. SHBG binds testosterone, making it common, while at the same time reducing SHBG can significantly increase the amount of free testosterone, namely its active form.
Decreasing hGH and increasing free testosterone greatly improves the efficiency of exogenous testosterone, as well as the efficiency of the whole AC course. That is why I.PRIMA is often used as an additional preparation on a course to decrease hGH. I.PRIMA can be added as the second drug on the course, as well as the third or fourth one.

Recommended working doses
20-30 mg per day tablets or 200-300 mg per week in injectable form. More preferred drug for amateurs, because of fewer side effects.
We ca recommend this drug because it has significantly fewer side effects compared to other anabolic steroids, so it is suitable for taking amateurs.
40-60 mg per day tablets or 800-1000 mg per week in injectable form. Large amounts of the substance can harm the liver if it is a tablet form or cause a greater number of side effects if it is an injectable form.
