Certificates of Analysis
Last updated: August 4, 2026
Below are the six batch Certificates of Analysis we hold, as the original PDFs. Three of them are thorough. Three of them test microbiology and nothing else — no metals, no identity, no potency, and no specification limits to read the results against.
We publish all six rather than the good ones. A page showing only the strong documents would be a more flattering page and a less useful one, and it's the exact move our own documents cluster exists to warn you about.
A COA covers one batch, not a brand. The lot on your bottle may not be a lot listed here. If it isn't, email info@flowbotanicals.com with the lot number and we'll send that batch's document — including the parts of it that are thin.
Lion's Mane Mushroom
Download PDF →Lot 2023-13956 · Made August 2023 · Best before August 2026
What this document covers
- Actives — total polysaccharides, 401.78 mg against a 400 mg label claim (UV-VIS)
- Heavy metals — lead, arsenic, cadmium, mercury, all passing (ICP-MS)
- Physical — weight, disintegration, capsule count
- Microbiology — plate count, yeast & mould, E. coli, Salmonella, S. aureus
What it does not
- A beta-glucan figure. Total polysaccharides by UV-VIS is a different measurement — see below.
Lion's Mane Mushroom
Download PDF →Lot B24H001 · Made September 2024
What this document covers
- Heavy metals — lead, arsenic, cadmium, all passing
- Appearance
- Microbiology — plate count, yeast & mould, E. coli, Salmonella, S. aureus, Pseudomonas
What it does not
- Any potency or actives figure. This lot was not assayed for what's in it.
- Mercury, which the other Lion's Mane lot does carry.
Mushroom Focus Strips
Download PDF →Lot KJ112501 · Made September 2025 · Best before August 2027
What this document covers
- Identity — all four species confirmed individually by LC-MS
- Potency — every species between 100.9% and 105.3% of its label claim
- Heavy metals — lead, cadmium, arsenic, mercury, all within limits
- Pesticides — complies
- Physical — weight, moisture, disintegration
- Microbiology — TAMC, yeast & mould, E. coli, Salmonella, Pseudomonas, S. aureus
What it does not
- Measured metal values. Each result restates its own limit as “less than”, so it is a pass without a number.
- The pesticide compound list. Our copy says “complies” without naming the panel.
Mushroom Energy & Cognition Drops

What this document covers
- Microbiology — plate count, yeast, mould, coliforms, E. coli, S. aureus, Salmonella
What it does not
- Heavy metals. No metals panel on this document.
- Identity or potency. Nothing here confirms what is in the bottle, or how much.
- Specification limits. The document has three columns — test, method, result — so there is no limit printed to judge a result against.
- Gluten. The row exists and its result reads “N/A”, meaning the test was not run.

Four things worth knowing before you read them
Metals are not tested on every lot. The Lion's Mane document carries a footnote: the metals assay runs on the first three lots, then annually. A passing metals panel is evidence about a testing programme, not proof about the specific bottle in your hand.
Our two Lion's Mane lots disagree with each other. Lot B24H001 reports arsenic at 2.34 mcg/serving; lot 2023-13956 reports 0.0913 mcg — around twenty-five times lower, both comfortably passing. The two documents also apply different lead limits to the same product, 2.75 mcg/serving against 0.5. We asked our supplier to explain the difference and have not had an answer. Read the metals article for what that does and doesn't mean.
Total polysaccharides is not beta-glucans. The 401.78 mg figure on the Lion's Mane document is a UV-VIS polysaccharide result. Beta-glucans are a subset measured by a different assay, and we do not have that number for any product. Anyone converting one into the other is guessing — here's why the distinction matters.
One product is in-house tested. The Focus Strips COA is the most thorough document in this set and it was not produced by an independent lab. That's also our only product made outside the USA. The difference is worth understanding.
