I have bought “raw” tirzepatide for an experiment . It tested 99.8 percent pure. I used a cheap scale and vialed it. I measured it with a cheap scale to 53 mg …..
so at the lab it weighed 55.78mg of powder, of which 51.64mg was Tirzepatide … so I was 2.78 mg off total weight …..
Resellers buy “raw “ tirzepatide” from a bulk factory by the KG and it is a near pure API ….. some then sell it raw , some have it mikes with salts, binders , and sterilized , re-lyophilzed and put into vials.
1) raw peptides aren’t sterilized
2) raw peptides are lyophilized ( freeze dried) during the filtering/ purification stage.
3) once they leave the original manufacturer you have no clue where they were……. Or possible contamination.
4) cheaper and smarter to buy a finalized product.
5) I bought it as an experiment to see if I could ballpark accurately measure a peptide, test it , vial it, then freeze it at -20 to -30 C for 3 years . I want to retest it and check its mg and potency …..
6) that I could do this and have an adequate “HPLC test should be a gut check . Anyone could do this and sell it .
6) I will destroy the test vials in 3 years
