Winstrol Stanozolol Pharmaceutical Raw Materials For Androgen Anabolic steroid C21H32N2O
Winstrol is a popular name for the anabolic steroid stanozolol. This compound is a derivative of dihydrotestosterone, although its activity is much milder than this androgen in nature. It is technically classified as an anabolic steroid, shown to exhibit a slightly greater tendency for muscle growth than androgenic activity in early studies.
While dihydrotestosterone really only provides androgenic side effects when administered, stanozolol instead provides quality muscle growth. The anabolic properties of this substance are still mild in comparison to many stronger compounds, but it is still a ggod, reliable builder of muscle.
Its anabolic properties could even be comparable to Dianabol, but Winstrol does not have the same tendency for water retention. Stanozolol also contains the same c17 methylation we see with Dianabol, an alteration used so that oral administration is possible. To spite this design however, there are many injectable versions of this steroid produced.
Since stanozolol is not capable of converting into estrogen, an anti - estrogen is not necessary when using this steroid, gynecomastia is not a concern even among the most sensitive individuals.
Since estrogen is also the cause of water retention, instead of bulk look, Winstrol produces a lean, quality look with no fear of excess subcutaneous fluid retention. This makes it a great steroid to use during cutting cycles, when water and fat retention are a major concern. It is also very popular among athletes in combination strength / speed sports such as Track and Field.
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 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.
Stanozolol is used by athletes and bodybuilders to lose fat while retaining lean body mass. It is usually used in a " cutting or leaning out " cycle, to help preserve lean body mass while metabolizing adipose, although it has not been proven conclusively that it has any special fat-burning properties.
