i personally have't used them but i've never heard anuthing bad about them. I stumbled upon ARL about a year ago and did a bit of research on them on various boards, the few bros that had used them gave excellent reviews on the products. i'm probably gonna use ARL for my next cycle.
I have seen positive results from ARL. I am by no means saying that they are accurately dosed. Only a lab test can prove that. I did have some gains from their Deca, EQ, Test & Primo. Good luck.
