Never mind them not being known and offering a suspiciously amazing price.
They misspelled Tirzepatide and incorrectly said it is 191 amino acids when in reality it's 39, also, there's no way it's rDNA origin nor is it intended for IM injections.
On the other hand, I do know what is 191 AA long and with rDNA origin, it's growth hormone, which is much cheaper.
Stop being a complete dummy and falling for every scam there is, just buy from normal vendors.
