When a new pep or blend catches my eye, my first move is to check the b/s/t listings across various groups. If something matches what I'm after, priced fairly, comes from a vendor I "trust," and has both a vendor COA and 3p, plus the seller has a solid reputation with plenty of good reviews and a good vibe from chatting with them, then I'll pull the trigger. In that case I'll purchase only the amount required for 1 cycle or to kick off a new regiment. So far I've gone through this process just once, and it turned out really well. Once I'm further along in the cycle, I'll share my experience here.
Also there are a few single vials websites that can work out to.
