Will Ceretropic ever get dihexa?

Seems like all the dihexa sources are out. Nyles7 is out, TrueLifeResearch is super shady. Is that it for dihexa?
It seemed like a pretty interesting noot and none of the sources have every guaranteed its purity (Nyles7's product was found to be only 90% dihexa). Cere has stuff like IDRA-21 so why not dihexa?
From reports by human guinea pigs, the effects seem to be pretty moderate, perhaps what one may receive from cerebrolysin.

> there are no analytical testing methods yet, nor does sigma carry a reference standard
So how were the chinese labs able to provide certificates alleging the purity of dihexa that has been made available to us so far?

They can finagle methods to show whatever they want. You can adjust your HPLC methods to make impure things look pure. That's why having reference standards, or validated HPLC methods, is a crucial for confidence in the purity of your product. It costs between $13,000 and $15,000 to pay for validated HPLC methods to be developed for a product without known reference standards. It's why I have not released Dihexa yet, and why I still have not brought out 7,8-DHF. Until I am confident in the ability to verify the identity and purity of a compound, it's more prudent to not release it.
Most Chinese labs use an NMR for molecular identity, and then HPLC for purity. However, if you ask them for their HPLC methods, many times they do not make sense, are not reproducible, or are clearly winged to get a favorable output.
