Finasteride, a reductase inhibitor, will not be effective in combating some of the androgenic side effects of oxymetholone. This is due to the fact that while oxymetholone does convert to dihydrotestosterone, this does not involve the 5 alpha reductase enzyme (2). Oxymetholone is a dihydrotestosterone based steroid. It differs only from dihydrotestosterone only due to the addition of a 2-hydroxymethylene group. This grouping can be removed metabolically which in turn would reduce the compound to 17 alpha-methyl dihydrotestosterone 1. It is this biotransformation that can explain, at least partially, the strong androgenic effect that oxymetholone has.
If it were around in the United States, it’s popularity would be comparable to oral Danabol. Effective dosages seem to be in the area of 200 mg a day taken in divided dosages. Andriol is a safe oral steroid that does not suppress gonadotrophins. It is absorbed through the small intestine into the lymphatic system, no burden to the liver it is a natural ester added to a synthetic derivative which will nor change liver enzymes. No testicular shrinkage, no reduction on in spermatogenesis will occur with reasonable dosages. Cholesterol triglycerides and total lipids tend to be reduced with long term use of Andriol as opposed to elevated with most oral steroids.
