First cycle, I'm assuming? Unfortunately, it's part of the game. A lot of things that can cause this, which include but aren't limited to carriers and levels of solvents in the gear. Then there's individual tolerances for the newly injected, foreign materials. My first run had my glute so fkn swole it was comical. You could see it thru my jeans, hurt like a bitch to get in and out of the truck, and def couldn't sit very easily on the side that was affected.

Couple tips are to start rotating your sites. Never pin that swollen site until it heals. Add the quads in. Start heating the oils before you pin. That'll loosen the consistency up a bit and help with dispersment to a degree and may help offset some of that reaction. Do not rub the site. Let it do it's thing, but you can add heat to the site with running water or heating pad. May wanna run to Tractor Supply or a feed store and get you a couple packs of 1.5" needles (23g); 1" may be too shallow for you. Add some NSAID's and vitamins to the mix and you'll be just fine. Adaptation isn't always a fun ride...

Is 1" going deep enough? How much fat on your glute? You may need 1 1/2" to get deep into muscle?

Add half cc of usp grape seed oil.
