Just dropping a quick review. Ordered some primo, anavar, test and pct stuff from Opti for the first time recently. Delivery (US East Coast) took about 10 days. Super fast, all items well packaged.
I don't really have a basis for comparison as this is my first time using primo but it hurts like hell the first couple injections but that was to be expected at a concentration of 200mg/mL and into virgin muscle. The other stuff I haven't used yet so no comment.
Overall, very satisfied. I just wish their MOQ was a bit more reasonable.
