Like methandrostenolone (Dianabol), oxymetholone does not bind well to the androgen receptor (AR), and many of the anabolism it supplies is by means of non-AR-mediated results. It is for that reason a Class II steroid and is finest stacked with a Class I steroid. Unlike Dianabol, nevertheless, it appears that oxymetholone is progestagenic.
When utilizing aromatizing steroids, progestagenic impact of oxymetholone is just an issue. With androgens such as Primobolan, oxymetholone stacks extremely perfectly and is a remarkably friendly drug. On the other hand, with testosterone it is an extremely extreme drug.
Oxymetholone does not transform to estrogen, and hence antiestrogens are not needed if no aromatizable AAS are being utilized. In performance with aromatizing drugs, oxymetholone is well-known for intensifying “estrogenic” signs, perhaps by producing progestagenic signs which the bodybuilder
puzzles as estrogenic, or by changing estrogen metabolic process, or by upregulating aromatase.
Compared to what bodybuilders anticipate of it, the drug is fairly moderate when no aromatizing steroids exist. I consider its strength around similar to Dianabol. It is not uncommon for a very first time user to do rather well on an oxymetholone-only cycle, however advanced users will desire
to stack with another steroid. Common usage is 50-150 mg/day, which must be divided into a number of dosages daily.
It is demanding to the liver since oxymetholone is 17-alkylated. It is much better to restrict usage to no greater than 6 weeks or ideally 4 weeks before taking a break of a minimum of equivalent length. Numerous users feel that it is better utilized in the start parts of the cycle, instead of in the last couple of weeks.
