Unfortunately, while a long acting version of Winstrol (Stanozolol) would be pretty cool, there are number of reasons to avoid the product pictured on the left, which claims to be Stanozolol Cypionate.
The 17-methyl group present on all commercially available Stanozolol preparations would interfere with the material needed to make the ester react with the steroid. In other words, actually attaching the ester would be very difficult, and especially for a 50mgs/ml (or higher) dose. Chemically, this is going to remain well beyond the abilities of 99% of the underground labs out there. I suppose they can try removing the 17-methyl group, then adding the ester, but again, we’re talking about something that would need to be done by a real chemist, in a real lab, and even then…I doubt anyone out there is doing this.…
In such a product, the 17-methyl would partially (or even fully in some cases) block enzymes (esterases) in the body from cleaving off the ester. If the body can not remove the ester, then there will be no active compound in the blood. At best, what you would be left with is going to be very weak when compared to the regular oral version or at worst, simply inactive.
Although it might be a cool idea, I just don’t think Winstrol Cypionate is going to be a worthwhile purchase for anyone.
