Absolutely a great company had a glitch problem on my end with a promotion that was up after I ordered and they made it right for me !

So I ordered a 30mg vial of triz and the first thing I’d like to rave about is the price point !! With shipping I paid under $120 and it came with a large syringe for reconstituting, a good bit of alcohol wipes, and also a full bag of syringes. I’ve ordered from about 3 different suppliers now & they are the first to add those on for no extra cost ! And secondly I did not know this but using bac water that’s very cold to reconstitute can ruin and cause your peptide to go foggy which means you should no longer use it.. well that’s what I did with mine like I’ve done before and it caused mine to go foggy which is of course my own fault and doing, now prior to this knowledge I had emailed onyx to see if maybe there was a way to fix it and they emailed me back so fast and without me even asking they helped me through it all and had already sent me a new bottle ! Most companies would not send you a replacement when they were not at fault for it being bad. I really cannot get over how great my experience has been with them. Will be recommending them to my family and friends for sure !!

Reliable fast shipping. Once, they forgot the needles I ordered and they refunded me for it immediately after I contacted customer service. Peptides always arrive and seem to be effective.
