In their own words
“I started carn injections last month and wow, game changer for sure.”
“I did, didn't do anything. Blame my meat eating self for not being deficient in it. It's a nice supplement for vegetarians or persons over 70, not for most other persons though.”
“yeah i helps burn fat if you take it before bed but it also gives you energy so i makes it a bit difficult to sleep for me at least”
