GR8 ChemS hey, i've found this cannabinoid (MDMB-PYRANACA) on some other website that is apparently also selling many other noids you have. 
They provided the IUPAC, which is methyl (S)-3,3-dimethyl-2-(5-methyl-1H-indazole-3-carboxamido)butanoate




If this is true, this is barely a precursor as there is no chain/ring substitution on the indazole. Also seems to be a pretty uncommon precusor, i have seen 5'-fluoro and 5'-bromo group, on some noids, but not 5'-methyl (if the interpretation from the picture above is correct - but it seems to be)

If there is no substituton of the indole, it is a very very weak substance, if it is even active, the chain is needed to bind to cannabinoid receptors with reasonable strength.
But the reviews seem to be pretty good for - apparently - inactive precursor..? And by the way where did you get the "PYRA" in the name from? I mean it implies theres a pyridine or something, but according to the formula, there is no substituion at all. 
Would you mind sharing the actual formula, if this one is not correct?
