Winstrol | Stanozolol
(a/k/a/ Winny, Winni V, Winstrol V)
Half Life: +/- 1 day
Formula: C21 H32 N2 O
Chemical Structure: 17beta-Hydroxy-17-methyl-5alpha-androstano[3,2-c] pyrazole
Facts: Winstrol is Dihydrotestosterone with a pyrazol group attached to the A-ring. It is not a great drug for weight gain (1), and it is primarily used in cutting cycles. It is one of the few drugs available as both an injectable form and an oral one.
In addition to its anabolic properties, Winstrol may be useful to lower Sex Hormone Binding Globulin (SHBG) (2) much more than other steroids. This could potentially make more testosterone (or other anabolic steroids that you may be using) more likely to remain free and unbound and hence biologically active.
Users often complain of sore joints from Winstrol in higher doses, and since it is a methylated compound (altered to survive the first pass through the liver without being destroyed), it can stress the liver (3). It is also notably harsh on both LDL and HDL cholesterol (3), and cardiac hypertrophy is a potential concern with Winstrol (4).
None of this means Winstrol is overly dangerous, but most men don’t stay on it for more than 6 weeks or so at 50-100mgs every day (regardless of whether the oral or injectable is preferred).
There is greater nitrogen retention (protein synthesis) with the injectable version (5) and it has a very weak Androgen Receptor binding ability (6). It is, however, very likely that SHBG inhibition is greater with the oral version.
Paradoxically, while protein synthesis is high with (7), weight gain is often minimal.
Practical Use: Because weight gain is so minimal on Winstrol, it is typically used in cutting cycles. Athletes would do well to avoid it, not only because it causes sore joints, but because it also can be detected easily.
Side Effects: Winstrol is a harsh steroid in many ways. Women can experience clitoral hypertrophy, hair loss, and acne. Men can experience hair loss, inhibition of their natural hormones, acne, and both sexes are subject to stressing their liver and altering their blood lipids unfavorably with Winstrol.
Used By: Winstrol is a popular addition to cutting cycles for both men and women. Winstrol is a decent enough drug in it’s own right, but is often seen as a less expensive version of Anavar. Both are typically used in cutting cycles, both are derived from Dihydrotestosterone, and both are widely available. Just like Anavar, Winstrolcan not convert to estrogen at any dose, and is not progestenic. It is, however, much more harsh on lipid profiles, and in my own experience, not as effective as Anavar. Still, the price makes it attractive, and it has been a staple of cutting cycles for decades.
Typical Dose: A typical dose for men ranges from a low of 25mgs/day to a high of 100mgs/day. Women typically stick with 10 milligrams per day.
Stacks Well With: Winstrol stacks well with virtually everything; in men testosterone and Deca-Durabolin are popular, while it is common for women to use it alone or with Anavar.
