Manufacturer: Geneza Pharmaceuticals
Pharmaceutical name: Nandrolone Phenylpropionate
Pack: 10 ml/vial (100 mg/ml)



GP Phenyl 100 by Geneza Pharmaceuticals is an injectable steroid containing 100mgs 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 this steroid 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. This steroid can be used for cutting or for bulking. Bodybuilders often stack it 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 100 as long as doses are kept within reasonable range. Bodybuilders using this substance 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 of this substance, 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 Durabolin in doses of 400-600mgs a week for 8-12 weeks, while women find a dosage range of 50-100mgs weekly to be sufficient for seeing desired results.

    I have used many other companies and products and this is one of my favorites so far. Couldnt be more impressed with GP and Gym-Candies. First time user with Gym-Candies and they just gained a customer for life. The whole process all around was perfect and most importantly their quality of products they carry.

  4. Mr. G

    Great product. Kicks in fast. Love the joint relief. Stacks great with test p. If you don’t mind jabbing eod then this will provide great results.

  5. Lavar Peoples

    I’ve been ordering from Gym-Candies for 9 years now and they have always sent my products. Also great products and prices.

    This is a great compound to experiment with at 100mg EOD. Just crushed it in the gym? Don worry, after a week on NPP you will barely even be able to tell the next day. Is it tough for you to get out of bed in the morning because of sore joints? Give it a week on NPP. No crazy mood swings like Tren A. You’ll notice your strength will increase as well. I don’t even notice any water weight and that’s one big reason I never ran Deca or NPP vs Tren. One of my new favorite compounds. Also running Prami for prolactin, exemestane low dose, test prop, oral tren 4x wk 1mg/day

    Love this stuff. Everything you want in a cycle. Kicks in fast, adds muscle, and awesome strength gains, very little water retention, and for me low side effects.. Ran 500mg GP Sus and 400mg GP NPP a week and that was plenty. It was just one fantastic training session after another. NPP is my go to compound, and GP my go lab.

  8. Patrick Lam

    Amazing product !! Starting a cycle of Test Prop + NPP, the strength gain was incredible!! Gained 10 Pounds of muscle in 4 Weeks.

  9. Robert

    WOW! A little goes a long way. I decided to run like 70mg a week after doing a 1CC EOD. Basically sprinkled some in with my GP Mast 200,100 EOD, and test cycle. While the mast made me hard and dry, the NPP filled me up. I had a great look. Was getting compliments from guys who can run large tren doses.

  10. Garbened

    GP NPP is great stuff. Quick to hit and the vascularity is off the walls! Nice increase in strength, very clean gains. Will definitely look to run this again in future cycles.

  11. Nick Farrell

    Great alternative to the longer ester Deca. big plus for me is the amazing joint relief and recovery this product comes with.
