A box of Mushroom Alchemy chocolates looks simple from the outside. The supply chain behind it isn't. Each batch passes through five rounds of testing before it reaches a customer, two outside labs are involved, and our internal rejection rate runs about 8% — meaning roughly one in twelve batches we make doesn't ship.
This is what happens between "we want to make this chocolate" and "this chocolate is ready to ship."
Round 1: Identity Testing on Raw Ingredients
Before any extract enters our facility, it gets identity-tested. This means confirming that the supplier sent us what they said they sent us. Hericium erinaceus for Lion's Mane. Cordyceps militaris for Cordyceps. Piper methysticum with Noble cultivar verification for Kava.
Identity testing uses DNA barcoding or HPLC fingerprint matching against a reference sample. It's the most-skipped test in the supplement industry — mostly because it costs money and most suppliers ship what they say they're shipping — but the rare case where it isn't true is the case worth catching.
About 1% of our raw ingredient shipments fail identity testing in any given year. Those shipments get returned, full stop.
Round 2: Potency Testing on Raw Ingredients
Each ingredient also gets potency-tested for its headline compound. Lion's Mane extract gets tested for beta-glucan percentage (Megazyme assay) and hericenone content. Kava extract gets tested for total kavalactone percentage and the Big Six profile. Cordyceps gets tested for cordycepin and adenosine.
We work with suppliers who consistently hit our potency thresholds, but every batch still gets independently verified. Suppliers have bad batches too.
Round 3: Contaminant Testing
Mushrooms are bioaccumulators. They absorb heavy metals from their growing substrate. Every batch of every ingredient gets tested for:
- Heavy metals: lead, cadmium, arsenic, mercury.
- Pesticide residues: a panel of 200+ compounds.
- Residual solvents: if the extraction used ethanol or other solvents, we verify they've been driven off below safety thresholds.
Our internal thresholds are stricter than the California Prop 65 standards (which are themselves stricter than federal FDA standards). About 2% of incoming material exceeds our internal thresholds and gets returned.
Round 4: Microbial Testing on Finished Product
Once a batch is produced and ready to package, it gets microbial-tested. We screen for:
- Total aerobic microbial count.
- Yeast and mold.
- E. coli.
- Salmonella.
- Staphylococcus aureus.
This is a food safety standard, but it's also a quality signal — contamination usually indicates a process problem upstream. We've never shipped a batch that failed microbial testing.
Round 5: Sensory and Stability Testing
The final round is taste, texture, and stability. Every batch gets a sensory panel review — the chocolate has to actually taste like our chocolate. We also run accelerated stability testing on a sample of every production run to confirm the active compounds remain potent through the expected shelf life.
Sensory is the most subjective round but probably the most important for repeat customers. About 4% of batches get rejected at this stage — usually for being technically passing but not quite right.
What Happens to Rejected Batches
Failed batches don't get rebranded and sold under a different label. They get destroyed. The cost of doing this honestly is one of the biggest line items in our quality program, and it's also one of the things that lets us sleep at night.
What We Publish
Every batch's COA is posted on our Certificate of Analysis page. You can look up the lot number on your specific package and see the actual lab report from the actual batch you bought.
Most brands publish a single "representative" COA from a particularly clean batch. We publish all of them. The variability is part of the honesty — small-batch production has natural variation, and pretending otherwise would be misleading.
Why This Costs More
Our finished-product cost is roughly 30–40% higher than competitive brands that skip rounds 1 and 3, or that use mycelium-on-grain instead of fruiting body extracts (see our label-reading guide). That cost flows through to retail pricing.
Customers pay the difference because the difference is real — lab-verified, batch-tested, and traceable to the actual ingredient sourcing. That's the trade we made when we started the company.

The testing isn't the marketing. The testing is the product.
