Testosterone Propionate often referred to as just “prop” test-p or “test prop” is a version of testosterone that promotes nitrogen retention in the muscle (6), and the more nitrogen the muscles hold the more protein the muscles store, and the bigger the muscles get. Testosterone Propionate can also increase the levels of another anabolic hormone, IGF-1, in muscle tissue. IGF-1 is alone highly anabolic and can promote muscle growth . It is responsible for much of the anabolic activity of Growth Hormone (GH). IGF-1 is also one of the few hormones positively correlated with both muscle cell hyperplasia and hyperphasia (this means it both creates more muscle fibers as well as bigger fibers).
This is a very popular anabolic steroids, which is a derivative of dihydrotestosterone. Winstrol is a relatively low androgenic steroid which will not aromatise. It is moderately toxic to the liver. Very few users report any water retention or any other side effects while using Winstrol. It is a popular drug for cutting in a stack with Primobolan or Parabolan. When stacked with Testosterone it can be very effective for a size and strength gain. Women use the drug quite often, but it can cause virilising effects for some women even at low dosages.
