Yes, NOW sells cordyceps for a pretty decent price. I'm not sure about the quality, like I said in another response. All of these seem to garner pretty high reviews, regardless of price and brand.

Here's the link to NOW https://www.amazon.com/NOW-Cordyceps-750-Veg-Capsules/dp/B0045X9VQC/ref=sr_1_3?keywords=cordyceps&qid=1552639143&s=gateway&sr=8-3

I read some stuff on Oriveda, and apparently it's touted because it's able to quantify the ingredient unique to lion's mane called terpenes. What I'm confused about is, what exactly is "terpenes?" I tried Googling it, but I couldn't find any info on "terpenes" pertaining to lions mane. I did find some stuff on terpenes in marijuana, but it seems to define marijuana fragrance/aromatics. I understand "terpenes" is unique to lions mane, but exactly what does this compound do, that we should desire high levels of it?

I know lions mane is reputed for neural growth factor, but what are the compounds responsible for it? Is it "terpenes?" Or is it something else?

I ask, because Oriveda claims to be the only company that quantifies terpenes. However, the studies available on lions mane, the proven studies that put the mushroom on the map, did not use Oriveda. I'm assuming they just used whatever brand available for the study.

I've read Amazon reviews for lions mane, and regardless of price and brand, they all have high reviews. So either the customers have no clue what they're talking about and they've falling prey to placebo, or "terpines" are overhyped, or other brands contain comparable levels of terpines even if they can't scientifically quantify the exact percentage level.
