Reddit reviews Cordyceps

Brands can make claims but unless those claims are backed up with actual test certificates I'd take it with a grain of salt. 1% adenosine is a high level, I wouldn't just take their word for it but ask for proof for sure.

I checked the Solaray one but I don't see 1% cordycepin mentioned anywhere. The Amazon listing has no specs at all, only 'biomass' (meaning 60-70% starch).

Looked that one up in particular because like you say C. sinensis hardly contains cordycepin/nucleosides, and biomass most likely won't contain anything that can be detected.

Why well because it is diluted by the starch and it is not extracted either, so whatever is there has bioavailability issues.

BTW, are you mixing up 'Solaray' with 'Solgar' maybe ? Solgar is a decent supplement brand, Solaray is only selling run-of-the-mill cheap stuff I think ?
