Boldenone Undecylenate Is Detatectable.
Boldenone Undecylenate 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.

When a follow up investigation is needed, laboratory reports/results ( . from a QMPI importer) should be forwarded to a CFIA inspector.
The CFIA Inspector will communicate with their respective Regional/Area Program Staff who will liase with the National Manager Technical Standards (or delegate), Fish, Seafood and Production Division. The follow up investigation approach may include, but not limited to gathering evidence of non-deliberate use, collecting and reviewing additional information, etc. , for an assessment and this will be determined on a case-by-case basis.
