Applications & Main Function


99% Winstrol Raws and 99% Stanozolol raws are the same products and one of the most popular and well-known anabolic 99% Steroid raws on earth.In fact, those who have never used anabolic steroids, if they can name a steroid it’s usually Winstrol or Stanozolol.


Our main products are Raw steroids, human growth hormone, Semi-finished oils, Bodybuilding peptides, SARMs raws, Anabolic steroids.Another important note often misunderstood about Winstrol forms is the C17-aa nature. Both oral and injectable Stanozolol are C17-aa anabolic steroids. Most oral steroids are C17-aa and while injectable steroids rarely are injectable Stanozolol is one of the exceptions. The injectable form is also commonly referred to as Winstrol Depot.

Stanozolol is subject to non-medically supervised off-label use by some athletes for its anabolic properties frequently presenting with concomitant reduction of body fat. Stanozolol is a modified derivative of dihydrotestosterone (DHT) and thus not aromatized to oestrogens via the aromatase class of enzymes (see chemical structure to right). Bodybuilders frequently misuse the term "dry" in describing their joint pain while using stanozolol either orally or via IM injection of an aqueous suspension; a reference to their perceived reason for an increase in joint pain. Rather, stanozolol as a DHT derivative can selectively compete with progesterone and other natural and synthetic progestins (nandrolone) for progestin receptors; yielding a reduction in progesterone mediated anti-inflammatory processes and presenting patients with a perception of increased joint discomfort.


Commonly used by athletes and bodybuilders alike to lose fat while retaining lean body mass.[citation needed] It is usually used in a "cutting or leaning out" cycle, to help preserve lean body mass while metabolizing adipose,[citation needed] although it has not been proven conclusively that it has any special fat-burning properties.
