Quick update on my review for those whom wanted more. Some time has passed, and I've had the opportunity to pin a couple of times, the Test Cyp to be specific. Whenever I try a new source, I pin my bicep, if PIP will happen it'll happen there. In this case, from Devon, zero pip in the bicep with test cyp. The only thing that I did notice out of the ordinary is that the oil seems to be more aerated? As in a lot of bubbles in the vial? Never seen that before, may mean nothing, but I have been known to pin Sust with a pic of a dog on the label, so there's that lol. Anyhow, so far so good, zero pip in 2 days bicep pin, just aeration? Hopefully someone knows what that could be, haven't come across that ever. Zero complaints, but curious...
