I tested them and theyre legit
In the peptide space there is always spmeone trying to make a quick buck or give you toilet water and ive been taking peptides for a good 5 years and my cousin recommended i try and test this site as they have super quick shipping times and are much more affordable than other spots when you account for the free shipping. Essentially i got ghk 100mg and also rta 10mg from them and i sent it off to NADiagnostics to have them run a test on the stuff in the vials to make sure its legit and I was very pleased to find that everything was exactly what it said it was AND the heavy metal testing also passed on all my vials (i ordered heavy metals testing because i dont see pspeptides posting it publicly so i decided it was worth testing for too). So for their shipping and prices and most importantly their lab tests coming back exactly as what i purchased id consider this an A+ source in the US and i will continue buying from them. In a 52 year old man so what goes in my body is a concern for me so Its crucial i have it tested.

We always stay up to date on testing and follow a standard testing protocol of every 2-3 months or when we release a new batch of any product! We are extremely happy to hear that beyond what our certificates show another 3rd party was able to verify our research products!
