DO NOT USE SOUTHERN SARMS!!!
IDK about the others you listed but for f*cks sake do not buy anything from southern sarms.
I've tried a few different distributors, blue sky peptides, evolution peptides, southern sarms, the only place that might be legit besides SarmsX is evolution peptides... MAYBE (I know their sildenafil is legit).
I'm saying this to help you, so you don't get fucked like I did, just buy from sarmsX. If you buy from southern sarms you will get sides, period. They have also been known to steal credit card numbers.
There is a reason everyone here recommends sarmsX, it's legit.
