GP Oxabol by Geneza Pharmaceuticals is an injectable steroid containing 100mg /ml of the hormone oxabolone cypionate.

Oxabolone is a nandrolone derivative however, a 19Nor compound. The 4-hydroxyl attachment, just like the 4-chloro attachment in clostebol, changes the affinity of the steroid for the aromatase and 5-alpha-reductase enzymes. By losing the interaction with the aromatase enzyme, oxabolone, unlike its parent nandrolone, cannot convert to estrogen. All estrogen related side-effects are therefore non-existent. No risk of gyno, no bloat as the result of water retention and so forth. As most of you may know, nandrolone also has progesterone binding properties, that worsened its estrogenic side-effects, but without the presence of estrogen, that no longer forms a problem. Its comparable to trenbolone. Trenbolone still possesses nandrolone’s progestagenic activity, but because it cannot aromtize its not an issue. This also means that Oxabolone can be used for cutting purposes, just like trenbolone. On the other hand, inhibiting interaction with 5-alpha-reductase will have an entirely different effect than it did with clostebol. Clostebol was a testosterone derivative, and the 4-chloro group inhibited formation of DHT in this manner. That made clostebol several times less androgenic in nature than testosterone, and made it a much weaker steroid as well. That’s not the case of oxabolone. The 4-hydroxyl group inhibits the formation of DHN (dihydronandrolone). But Unlike DHT, DHN is an extremely weak androgen. So by eliminating it, you are in fact increasing the androgenic potency of nandrolone, especially in target tissues like scalp, skin and prostate, which does increase the risk of androgen related side-effects. But it also makes it a much stronger steroid. Nandrolone being quite a decent androgen to begin with, inhibiting reduction to DHN makes it that much stronger, and truly comparable in action to the steroid trenbolone. It would exert a distinct hardening effect on the body, and would be a non-aromatizing hormone still capable of packing on a notable amount of lean mass. Which can be said of very few steroids. It would be the perfect lean mass builder.

It makes for an ideal cutting steroid, the perfect anti-catabolic to retain maximum lean tissue while reducing body-fat. But also a lean mass gainer, well suited for packing on small amounts of lean mass, while not increasing body-fat or water retention as most mass steroids will do. In these aspects its understandably best stacked with Equipoise (boldenone undecylenate) or Primobolan Depot (Methenolone enanthate) as a base compound for the best results, and all or not with Winstrol (stanazolol), Proviron (Mesterolone), Halotestin (Fluoxymesterone) or Anavar (oxandrolone). Using 400 mg a week of oxabolone alongside 300-400 mg of Primobolan Depot or Equipoise weekly for 8-10 weeks, and perhaps 50 mg/day Winstrol or 30-40 mg a day Anavar for even better effect. Since it does not aromatize, the use of anti-estrogens is not needed. Most side-effects associated with oxabolone would be linked to its extreme androgenic nature. Acne, hair loss and prostate hypertrophy are a risk.
