Injecting LR3 won't give you permanent site enhancement. Injecting anything (even just bac water by itself) will give you local site enhancement and it might even feel great because of the increased swelling and pumps but it's not causing actual muscle growth. Even injecting traditional SEO which can transform your arms isn't permanent. I have done it all and LR3 is one of my fav things to run but don't think it's going to permanently increase the size of the muscle you inject it in. LR3 is like a super GDA to me and I am a massive fan but just being realistic. The only things causing permanent size are injecting things like silicone or pmma which stay in the muscle.
When guys are injecting a certain bodypart every single day what do you think will happen. Even if the injection volume is tiny those injections cause inflammation and that inflammation sends signals to the rest of your body. With SEO you have actual oil in your muscle which dissipates very slowly so that causes extra "growth" a long with the swelling which creates the illusion of even more "growth". With a small amount of LR3 you are basically just getting the swelling part of the equation which can still feel great especially if you are injecting everyday. It's only going to help grow that body part (and improve your physique) so I am by no means stating it won't help but I don't want people believing LR3 is some magical drug that causes the muscle you inject it in to grow because it simply won't.
