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 NPP (Nandrolone Phenylpropionate) as long as doses are kept within reasonable range.
Using a randomized "double-blind" "placebo-controlled" design, 16 experienced male bodybuilders (age: 19-44 yr) either received ND (200 (-1), intramuscularly) or placebo for 8 wk. Body composition was assessed using the four-component model, combining results from underwater weighing, dual-energy x-ray absorptiometry (DXA), and deuterium dilution. Total bone mineral content and density were measured using DXA. Water compartments (extracellular water [ECW] and intracellular water [ICW]) were determined using deuterium dilution and bromide dilution.
