One of my friends swears by them and sent me a few dated CoAs, for instance:

Happy to share the rest of the CoA, dating from August to September 2025.
I've personally only used the vendors listed on this forum.
As far as I know, they have two websites:
1. https://www.liyupeptide.com/
2. https://www.liyudaily.com/
Wondering if anyone has any experience with them?
