Peptide Critic Community

@glpbacon I found the same intel. It appears a lot of peptide companies are forgoing the heavy metals testing because they will "pop" and the levels are so low it doesn't cause a concern. I'm a transparent person and I want my customers to know what they are putting in their bodies!

@jackiew1 There are no US based suppliers! And if there were they aren't testing for heavy metals. Majority of peptide companies are only testing purity, endotoxins and vial strength/potencey.

@jackiew1 I have a suppler in China...just like everyone else.

I recently had 7 peptides tested from a 3rd party and 3 of the peptides popped for arsenic and lead. The metal levels are within commonly accepted pharmaceutical elemental impurity limits and would generally be considered low-risk from a heavy metals standpoint. But, I need some feedback from others on this. A lot of companies aren't even testing for heavy metals!
Arsenic
GHK-Cu: 0.60 µg/vial
TB-500: 0.56 µg/vial
Retatrutide: 0.53 µg/vial
MOTS-c: 0.51 µg/vial

Lead
GHK-Cu: 0.91 µg/vial
