ANADROL (oxymetholone) tablets for oral administration each contain 50 mg of the steroid oxymetholone, a potent anabolic and androgenic drug.

Like methandrostenolone (Dianabol), oxymetholone does not bind well to the androgen receptor (AR), and most of the anabolism it provides is via non-AR-mediated effects. It is therefore a Class II steroid and is best stacked with a Class I steroid. The drug appears to give the same benefits as Dianabol. Unlike Dianabol, however, it seems that oxymetholone is progestagenic. It has been observed to cause nipple soreness or to aggravate gynecomastia even in the presence of high dose antiestrogens, strongly suggesting that the effect is not estrogenic. That effect can be reduced by concurrent use of stanozolol (Winstrol), which is anti-progestagenic. This progestagenic effect of oxymetholone is only a concern when using aromatizing steroids. With androgens such as Primobolan, oxymetholone stacks very nicely and is a surprisingly friendly drug. In contrast, with testosterone it is a very harsh drug.

Water retention is considerable, so that the muscle diameter quickly increases and the user gets a massive appearance within record time. Since the muscle cell draws a lot of water, the entire muscle system of most athletes looks smooth, in part even puffy. Anadrol 50 does not cause a qualitative muscle gain but rather a quantitative one which in the off-season is quite welcome. Anadrol 50 “lubricates” the joints since water is stored there as well. On the one hand this is a factor in the enormous increase of strength and on the other hand, it allows athletes with joint problems a painless workout. Powerlifters in the higher weight classes are sold on Anadrol 50.
