How to Find the Lab Report for Your MIT45 Product by Lot Number

A walkthrough of where MIT45 posts its certificates of analysis, how to match one to the batch code on your product, and which fields to check once you have it open.

Short answer: MIT45 posts its certificates of analysis (COAs) on a Product COAs page, which you reach from the "Transparency" link in the site footer. The page is organized by product: Gold, Super K, Super K Extra Strong and Go when we checked in October 2026. Each product has a "Finished Product COA" link. Find the batch or lot code printed on your product and compare it with the code on the report. If your batch isn't listed, the page tells you to use the site's search box to find it.

Below are the steps, what a matching report looks like, and the fields worth checking. We describe what the pages showed when we checked, and MIT45 can change them at any time.

Step by step

1. Find your batch code. Look on the bottle label and the outer box for a code labeled lot, batch or similar. The COAs we opened used codes like 00-2098 and 00-2500-S. MIT45's pages don't say exactly where the code is printed. If you can't find it, contact MIT45 through the contact page on its site before using the product.
2. Go to the COA page. On MIT45's site, scroll to the footer, open "Transparency" and click "View All COAs." That opens the Product COAs page (mit45.com/product-coas/). Product pages also link to a certificate-of-analysis page from their "third-party testing" text.
3. Pick your product. Each product section lists a Finished Product COA, separate ingredient COAs (water, vegetable glycerin, kratom extract, citric acid), a spec sheet for most products, and an FDA registration document for the facility.
4. Open the Finished Product COA and compare the batch code with your package, character by character. The code is also in the PDF file name.
5. If it doesn't match, use the site search, as the COA page instructs: "If you can't find your batch below, use our website search above to find it." Search the code exactly as printed.
6. Still nothing? Email MIT45 with a photo of the code and ask for the report. Until you've seen it, treat that unit as untested.

What the posted reports looked like

We opened two finished-product COAs from MIT45's page in October 2026. Both came from Cambium Analytica in Traverse City, Michigan.

Two things stand out. First, the batches posted are specific, dated batches. If your product is from a newer batch, you need that batch's report, not whichever one is on the page. Second, the two finished-product reports didn't carry identical panels. If a report you open lacks heavy-metal or solvent results, check the kratom-extract ingredient COA in the same product section, or ask MIT45 which report covers them.

The label figures are close to the COA figures but not identical. MIT45's Gold page states 125 mg of mitragynine per bottle on new packaging and 112.5 mg on old packaging. Super K's page states 150 mg. Some gap between a label claim and a measured result is common. A large gap is worth asking about. Our MIT45 review covers the brand more broadly.

The fields to check on any COA

1. Batch or lot code: it must match your package exactly.
2. Sample description: product name and size should match what you bought (for example, a 15 mL vs a 30 mL bottle).
3. Lab name, address and accreditation. ISO/IEC 17025 is the standard testing-lab accreditation. Our lab accreditation guide explains what it does and doesn't prove.
4. Dates. When the sample was received and when results were published. Very old reports on a fresh product deserve a question.
5. Alkaloids: mitragynine and 7-OH at minimum, with units. Many state laws cap 7-OH. Mississippi, for example, sets 1% of total alkaloids and 0.5 mg per container.
6. Contaminants: heavy metals (arsenic, cadmium, lead, mercury), microbes (Salmonella, E. coli, yeast and mold) and, for extracts, residual solvents.
7. Pass/fail and action limits. A "pass" means little if no limit is listed. Look for the limit next to each result.
8. Signatures from the lab's reviewer or director.

Finished-product vs ingredient COAs

MIT45's page links two kinds of report, and they answer different questions:

• Finished-product COA: a test on the product as sold, the liquid in the bottle. This is the one to match to your batch code, because it reflects what you actually have.
• Ingredient COAs: tests on raw materials before they were combined, here the kratom extract, water, vegetable glycerin and citric acid. They're useful for checking contaminant panels on the extract, but they don't confirm the alkaloid content of your finished bottle.
• Spec sheet: the manufacturer's target specifications. It's a statement of intent, not a test result.
• FDA registration document: shows the facility is registered with the FDA. Registration isn't FDA approval of the product, and the FDA has not approved any kratom product.

When you find your report, save a PDF copy along with a photo of your batch code. If you ever need to report a problem or check a recall, you'll have the evidence even if the page changes.

Red flags when matching a COA

• The code on the report and the code on your bottle differ, even by one character or suffix.
• The report describes a different product or size.
• No lab name or address, or a lab you can't find independently.
• Results with no units or no limits.
• A report that looks edited: mismatched fonts, missing pages, cropped headers.
• A product with no batch code at all.

Any of these is a reason to contact MIT45 before use. If you think something is wrong with the product itself, see our guide on checking for kratom recalls.

What a COA can't tell you

A clean COA shows that a sample from that batch met the panel the lab ran. It doesn't make kratom safe for you. Regular use can lead to dependence, and mixing with alcohol, opioids or sedatives raises the risk. The FDA has not approved kratom for any use, there is no established safe dose, and anyone considering it should talk to a clinician first.
