Nootropics Depot quality under-represented on new supplement app

Posting this to make ND team aware that supp.co just had their public launch and has some pretty heavy hitters in terms of influence for their board members / advisers. The app is actually useful for tracking my stack, finding substitutes, etc. However, ND’s quality is mischaracterized - for example their COAs are not acknowledged.
I am hoping that ND could reach out to their team as I believe the app has potential to drive people to ND’s products.

I understand the California prop 65 is overly restrictive. I remember consumerlab had tested greens, Chlorella and Spirulina. With spirulina their concern was the tested products either had heavy metals or tablets didn’t disintegrate when mixed in water for 30 min. Now because of how bad spirulina tastes, it’s difficult to consume it as a powder. Separately I’ve read concerning reports about most spirulina products being contaminated with Microcystin A which is a liver toxin

I had not heard of microcystins. It looks like the way to assay that is via ELISA on a microplate reader. We actually just bought one of those for our cell culture lab! I'll have to see what it would take to get some kits. It looks like the biggest issue for microcystins is in drinking water, as you are consuming a lot of it. It seems like the levels potentially present in spirulina are significantly lower than the limit for toxicity.

We are also only using 1g of it in the greens stack, so the dose is lower. I'll see about getting some ELISA kits, though. Could be interesting to test.
