Tested the primo 100. Honestly, I am really just trying to find an actual source of anavar and primo because they are widely regarded as the best. I normally just buy the smallest dose of these two as they cost the least, with the expectation they are not real. This way when the test comes back as being an exact match for something else I don't get pissed. Of the 4 sites I've tried so far this strategy has been pretty effective as the anavar was dbol 3 times and tbol 1 time. The primo has been boldenone all 4 times. I get that the roidtests are sometimes inaccurate. It's actually pretty easy to tell when they are inaccurate. The way you can tell is the solvent in the vial is either crystalized or non-existent. I sent two kits back for this very reason and got them replaced with valid ones. When the solvent is liquid and clearly visible, every time has been an exact match to the substance these compounds are most commonly faked for. Every time I've tested less expensive stuff like dbol, superdrol, or anadrol they come back as exact matches for the correct compound.
