Like most forms of testosterone in the US and North America, it is only legal to buy Sustanon with a prescription from your doctor. Due to its long-estered formula, many physicians actually prefer it to other versions of the hormone because it requires fewer office visits and more convenience. As such, it is often easier to find this product in the underground market simply because it is widely available. On the other hand, the purchase, possession, and use of Sustanon are illegal without a prescription. Before you buy Sustanon, make sure you understand the potential legal implications.
Equipoise is not an ideal steroid for the drug tested athlete however. This drug has the tendency to produce detectable metabolites in the urine months after use, a worry most commonly associated with Deca-Durabolin. This is of course due to the high oil solubility of long chain esterified injectable steroids, a property which enables the drug to remain deposited in fatty tissues for extended periods of time. While this will reliably slow the release of steroid into the blood stream, it also allows small residual amounts to remain present in the body far after the initial injection. The release of stubborn stores of hormone would no doubt also be enhanced around contest time, a period when the athlete drastically attempts to mobilize unwanted body fat. If enough were used in the off-season, the athlete may actually fail a drug screen for boldenone although many months may have past since the drug was last injected.
