No, I did not aspirate. It is too hard to do it with onw hand. My GF will be doing the rest and she will aspirate. I had a buddy do a 8 week cycle all by himself and never aspirate (all glute shots). Besides, from my first experiance, I cannot see how that is 100%. I noticed that It is near impossible to keep the needle from going down deeper when you inject. What would happen if the vein is 1mm deeper? Or if it is 1mm closer to the surface? I mean, the dart was moving up and down as I pushed on the plunger. Kinda hard to explain......
