Being a supplement nerd I found this case to be highly interesting. I can't remember now but for some reason this supplement company called Nootropics Depot was suspicious aboout turkesterone and tested a bunch of supplement companies products, I think it was a dozen or so. Every single one of them was fake. Nootropics Depot thinks some of the supp companies bought the raw material in good faith from China. It showed up as legit on some testing too but with more advanced testing he found out that the extract was like 2% turkesterone. Don't trust the Chinese was his message. They will sell anything and trick you.
Why this turkesterone stuff is so sought after I don't know. There's no evidence it does anything in humans.
Ive been listening and reading Rob Regish's stuff for over a decade. He has studied the ecdysterones like no other. (Turk is an analog of Ecdysterone).
He said from the get-go all of the stuff out there is fake basically. (Except some foreign select Ecdy's). He loses out on a lot of money each year just by being honest.
The Ecdy's (like Turk) are only grown once a year for a short time, and then used up, and for 1/2 the year "not available".
So MASS Supps (Synthagen) refuses to keep making Syntagen for 1/2 the year because the owner is honest about it and will only use the real stuff.
I believe the real stuff comes from Siberia (dont quote me on it) but its not China. Synthetic and weak crap...
Even the good stuff is just an adaptogen (recovery). No ones getting big on plant anabolics... (Not even plants).
