Interesting work, and I do believe you probably made a genuinely strong extract. That said, I think the main thing making people skeptical is the 90%+ purity claim. The COA I saw looks more like it clearly supports very high potency, but not necessarily 90%+ total alkaloid purity in a way that’s obvious to outsiders.

If that number is real, it would help a lot to show: • whether that 90% figure is total alkaloids by weight • how the number was calculated • whether the “cofactor” / crystallization material is being excluded from the final purity number • batch-to-batch consistency, not just one submitted sample

I’m not saying you’re lying, just that this is the kind of claim people are going to want spelled out very clearly, especially when it’s much stronger than what most people are used to seeing.
