Lab Testing
Lab testing
Every batch. Every cannabinoid. Every time.
Independent, ISO-17025 accredited laboratories test every batch we sell. The results are public, batch-indexed, and linked to the product in your hand. Here's exactly what we check and why it matters.
Why third-party testing matters
The hemp industry is federally legal but lightly regulated at the consumer level. Without mandatory testing, a brand could put anything in a package and call it whatever they wanted. Some do.
Third-party, ISO-17025 accredited labs are the independent check. They have no financial incentive to approve a batch and no relationship to the brand beyond the tested sample. The ISO-17025 standard specifies how the lab is equipped, calibrated, and audited — it’s the same standard used for pharmaceutical and forensic testing. When we publish a COA from an ISO-17025 lab, it is a verifiable statement about what’s in the product.
If a brand won’t publish current, batch-specific, third-party COAs — or hides them behind a QR code that no longer resolves — assume the worst. The COA is the product.
What we test for
Cannabinoid potency
Full cannabinoid profile — Δ9-THC, Δ8-THC, Δ10-THC (where applicable), THCa, CBD, CBDa, CBG, CBGa, CBN, THCV, HHC, and any other cannabinoids present in the product line. Reported in mg per unit and as a percentage by weight.
Residual solvents
Extraction processes use solvents (ethanol, hexane, CO₂). Testing confirms that none remain in the final product above the strict limits set by state cannabis programs and USP Chapter 467.
Pesticides
Screened against a panel of 60+ pesticides commonly found in cannabis and hemp cultivation, including glyphosate, myclobutanil, bifenazate, and abamectin. Must be non-detect or below state action limits.
Heavy metals
Lead, cadmium, mercury, and arsenic. Hemp is a bioaccumulator — it absorbs what’s in the soil — so this test is non-negotiable. Must be below California’s Proposition 65 action levels for oral consumption products.
Microbial contamination
Total yeast and mold, aerobic bacteria, E. coli, Salmonella, and mycotoxins (aflatoxins, ochratoxin A). Must be non-detect for pathogens and below strict CFU limits for general microbial count.
Moisture & water activity (flower)
Flower is tested for moisture content and water activity. Too high and you get mold growth; too low and the flower is harsh and fragile. Target: 10–13% moisture, <0.65 water activity. [/d8_page_section][d8_page_section title="How to read a COA"] When you open a COA from our COA page, you’ll see:
- Sample identification — our product name, batch number, and sample ID assigned by the lab.
- Receipt and analysis dates — when the lab received the sample and when it was tested.
- Testing methods — typically HPLC for cannabinoids, GC-MS for residual solvents and pesticides, ICP-MS for heavy metals, and plate culture for microbials.
- Cannabinoid panel — each cannabinoid with its concentration and the method’s limit of detection (LOD) and limit of quantitation (LOQ).
- Pass/fail determinations — for each test category, the report indicates whether the batch passes the state action limits.
- Analyst signatures — the lab technician’s name and credential.
Matching the COA to your product
Every product we ship has a batch number printed on the label. To verify:
- Find the batch number on the product (usually on the bottom of the package or on the tincture label).
- Go to our COA page and search for that batch number.
- Open the PDF — the batch number on the COA should match exactly.
- Check the date and the potency values against the label claim.
If you ever find a discrepancy, tell us. We’d rather pull a batch than let a mislabeled product sit on our shelf.
Our labs
We rotate between several ISO-17025 accredited labs to reduce conflicts of interest and to benefit from each lab’s equipment strengths. The labs we currently use include:
- InfiniteCAL Laboratories — California and Florida locations
- ACS Laboratory — Florida, specialized in hemp cannabinoid testing
- Kaycha Labs — multi-state DEA-registered lab
Each lab’s accreditation certificate is available on request. Lab selection is driven by capacity, turnaround time, and sample type — not by a relationship or pricing arrangement that could bias results.
Frequently asked about testing
How often are products retested?
Every batch is tested once before it’s released for sale. For long-shelf-life products (gummies, tinctures) stored beyond 6 months, we retest for potency degradation before continuing to sell from that batch.
What happens if a batch fails?
It’s rejected. We don’t re-label, re-blend, or “adjust” a failing batch to sell it. Failed batches are returned to the manufacturer or destroyed, depending on the failure mode.
Do labs ever get it wrong?
Analytical testing has a margin of error, usually ±10% for potency. Instruments can malfunction or samples can be contaminated during collection. If a COA result seems wildly inconsistent with the expected value, we ask for a retest — sometimes at a different lab — before making any decisions.
Why don’t all products list identical cannabinoid panels?
Different product types have different analytical requirements. A CBD tincture doesn’t need to be tested for residual solvents if it’s extracted with ethanol-free methods. A flower product doesn’t need a microbial panel as extensive as an edible. Lab scope matches the product’s regulatory category.
