GP Phenyl

GP Phenyl is an injectable steroid containing 100 mg per ML of the hormone Nandrolone Phenylpropionate.

Unlike its relative, Nandrolone Decanoate, the ester of this Nandrolone makes it very fast acting and therefore makes it possible for the compound to be out of the body much more quickly. This makes GP Phenyl a better choice than Deca for tested bodybuilders and athletes. Users typically follow a dosage schedule of every other day when using this substance to keep blood levels elevated and stable.

Durabolin, as it is often called, is one of the most popular steroids being used amongst bodybuilders today. Durabolin is a low androgenic steroid with high anabolic effect. It will aromatize in high dosages, but not at the rate of testosterone. Progesterone buildup is one side effect that some have trouble with although users report that the problem isn’t as bad with this ester as it is with Deca. Users sensitive to these issues might choose to add Cabaser or Dostinex to their cycle.

GP Phenyl  can be used for cutting or for bulking. Bodybuilders often stack GP Phenyl with Testosterone for one of the most common and effective bulking cycles. The Durabolin / Winstrol stack is also very popular. It is believed that Winstrol helps block the progesterone buildup while the Durabolin heIps with the joint issues that some suffer while on Winstrol. The joint relief and healing that durabolin provides is one of the main reasons it has become a very popular steroid with bodybuilders. Androgen side effects are typically not an issue with GP Phenyl as long as doses are kept within reasonable range.

Bodybuilders using GP Phenyl by itself sometimes report a loss of libido, therefore, it is recommended that one run at least a small dose of testosterone or even a high androgen like Proviron to help prevent this issue.

Women bodybuilders are also fond GP Phenyl, where it’s mild androgenic nature makes it a safe steroid for them to use without fear of masculizing side effects. Durabolin will shut down one’s body’s ability to make it’s on natural testosterone, therefore a proper PCT program is recommended following a cycle of this substance.

Male bodybuilders often use GP Phenyl in doses of 400-600 mg a week for 8-12 weeks, while women find a dosage range of 50-100 mg  weekly to be sufficient for seeing desired results.
