Methenolone (Primobolan 500 Gen-Shi Labs.) is an anabolic and androgenic steroid, better known under the trade name Primobolan. Chemically it is a derivative of dihydrotestosterone. Has a rather weak effect on the body, somewhat inferior to pure testosterone. The steroid is available in tablets and in injectable form (Primobolan depot).
The active substance of Primobolan in tablets is Methenolone Acetate (Metenolone Acetate). It has a very short period of action – no more than 5 hours. At the same time the price of the drug is quite high. The main advantage of the tablets is the absence of negative effects on the liver.
Primobolan Depot is an ether of methenolone enanthate (Methenolone Enanthate), an injection form. With the introduction of a steroid, it accumulates in fat stores, after which it gradually enters the blood. Has a long period of validity. The disadvantage of this form is the painfulness of injections (especially this is important for beginners). Injectable methenolone acetate is also found, but it is less popular.
Most athletes prefer injections of Primobolan Depot to taking tablets. Injections of methenolone are more effective (part of the oral drug is destroyed in the liver) and are cheaper.
As to how to take Primobolan with other AAS, then for the set of muscle mass in the course you can include Nandrolone, various testosterones, Oxymetholone, Sustanon and Methandrostenolone, for “drying” – Winstrol. The most safe mass-gathering combination is Metenolone with Nandrolone (almost no side reactions occur on the course, with minimal retracement phenomenon). It is not recommended to use combinations of steroids from more than two drugs. The mixed course is best limited to half the dosages – this will achieve synergy and reduce the possibility of side effects. For women, combinations are not the best choice.
