Many beginners make first steroid experiences with methenolone. It is milder than many other steroids and has significantly fewer side effects. However, the weight gain and the increase in force are also significantly lower than by other steroids.

Metenolon was then much sought after and considered as a very mild steroid. In the end, it was not so mild and free of side effects, as we have seen today. For a long time, Metenolon was considered a starter steroid. For bodybuilders who have already had experience with stronger steroids, methenolone (neither in the acetate nor in the enatate form) is suitable neither for the build-up nor for the settling phase to maintain the muscle mass.

General experience of bodybuilders who have taken methenolone speak of a mass increase of just 3 – 4 kg in 6 weeks. The tablet version (metelonone acetate) is, however, discouraged, since the active ingredient is very poorly absorbed and is therefore no longer available for the purpose to be fulfilled. In order to achieve a better efficiency, body builders usually use the injection-variant (Methenolonenantat).

Methenolone acetate products (tablets) today come mainly from Japan and South Africa.
Today, methenolonenate products (ampoules) come mainly from Mexico, Spain and Turkey.
