Winstrol is a popular brand 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. Admittedly the anabolic properties of this substance are still mild in comparison to many stronger compounds, but it is still a reliable builder.
Its efficacy as an anabolic could even be comparable to Dianabol, however Winstrol® does not carry with it 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.
Combined with products like Primobolan, Masteron, Clenbuterol or T3 Cytomel for a slimming or in combination with testosterone or oral steroid such as Dianabol for an increase in power and lean mass gain, this product does not cause retention water or excessive weight gain.
