Bolasterone
Androgenic: 300
Anabolic: 575
Standard: Methyltestosterone
Chemical Names: 17beta-Hydroxy-7,17alpha-dimethylandrost-4-en-3-one 7,17-dimethyltestosterone
Estrogenic Activity: high
Progestational Activity: N/A
Description:
Bolasterone is an oral anabolic steroid structurally related to methyltestosterone. It differs only by the addition of a methyl group at c-7, which accounts for its given chemical name, 7,17-dimethyltestosterone. The added c-7 methyl group makes the activity of this steroid far removed from methyltestosterone, however, such that any direct comparison is difficult to justify. For starters, bolasterone is a fairly potent steroid, measured in human subjects to have approximately twice the anabolic effect of methandrostenolone. This is in contrast to methyltestosterone, which is considerably less potent than methandrostenolone. Despite being a testosterone derivative, bolasterone is also much more anabolic than androgenic in nature. At a given therapeutic level, it is much less likely to cause androgenic/virilizing side effects. It does have one strong similarity to methyltestosterone, however, which lies in the fact that bolasterone too is quite estrogenic. Both agents are, therefore, most appropriately used during bulking phases or training.
Administration (Men):
Clinical studies have demonstrated that significant nitrogen retention and weight gain can be induced with a daily dosage of 1-2mg per day. In the athletic arena, doses of 2-5 mg daily seem to be most reasonable, taken in cycles lasting no more than 6-8 weeks in length to minimize hepatotoxicity. This level is sufficient fer strong increases in muscle size and strength, although such gains will likely be accompanied by significant water retention.
Availability:
Bolasterone is no longer produced as a prescription drug, although a handful of underground laboratories have taken to selling this material.
