A Certificate of Analysis is a laboratory document reporting the measured composition of a specific production batch. When you scan the QR code on one of our preparations or enter a batch number in the COA portal, what you receive is the actual test record for the batch in your hand — not a sample result, not an average across recent batches, but the specific analytical data from the batch that was tested.

COA formats vary somewhat between laboratories, but the core structure is consistent. This guide walks through each section so the document reads clearly rather than as a wall of unfamiliar terminology.

I

Laboratory Information

The top section of a COA identifies the testing laboratory — its name, accreditation credentials, contact information, and the date analysis was conducted. The accreditation credentials are the first thing worth checking. Accreditation from a recognized body — ISO/IEC 17025 is the relevant standard for analytical testing laboratories — indicates that the laboratory's methods, equipment, and quality systems have been independently verified. An unaccredited laboratory's results carry less interpretive weight than an accredited one's, because accreditation is the mechanism that validates the testing process itself.

All testing we commission is conducted by accredited third-party laboratories. The laboratory has no stake in the results — their job is accurate measurement, and their accreditation is their commitment to that standard.

II

Batch Identification

The batch identification section confirms that the COA in front of you corresponds to the preparation in your hand. It lists the product name or sample description, the batch or lot number, the date the sample was received by the laboratory, and the date testing was completed. The batch number on your bottle and outer packaging should match the batch number on the COA exactly. If they don't match, the document you are looking at is not the test record for your batch.

How to verify your batch

Every preparation we produce carries a batch number printed on the bottle and outer packaging. Enter that number at the COA portal or scan the QR code on the label. The record returned corresponds to the specific batch that was prepared, tested, and delivered — not a prior batch with similar characteristics.

Cannabinoid Profile (Potency Panel)

The potency panel is where cannabinoid concentrations are reported. Values are typically expressed as a percentage by weight, as milligrams per gram, or as milligrams per unit — and sometimes all three. The labeled strength on our preparations is derived from the milligrams per unit value, which is what the potency panel documents for each cannabinoid present in measurable concentration.

Compound
Form
What It Indicates
CBD
Neutral (decarboxylated)
The primary cannabinoid in most hemp tinctures. Labeled concentration corresponds to this value.
CBDA
Acidic precursor
The pre-decarboxylated form of CBD, present in varying amounts depending on preparation method. Full-spectrum preparations may retain measurable CBDA.
CBG
Neutral (decarboxylated)
Present in our CBG-dominant tinctures as the primary labeled compound; present as a minor cannabinoid in CBD-dominant preparations.
Δ9-THC
Neutral
The regulated intoxicating cannabinoid. Must remain at or below 0.3% by dry weight for legal hemp classification. Our full-spectrum preparations retain trace amounts within this threshold.
THCA
Acidic precursor
The non-intoxicating acidic form of THC present in raw plant material. Used in the Total THC calculation along with Δ9-THC.
Total THC
Calculated value
A regulatory calculation combining Δ9-THC and THCA (using a conversion factor). This is the figure evaluated against the 0.3% legal threshold. It does not imply intoxication potential at the concentrations found in compliant hemp preparations.
CBC, CBN, others
Minor cannabinoids
Minor cannabinoids present in the plant are reported when they are present in measurable concentrations. Their inclusion reflects the full-spectrum character of the preparation.

On acidic vs. neutral forms

Cannabinoids occur naturally in acidic form in the living plant and convert to their neutral forms through decarboxylation — triggered by heat, time, or processing. A full-spectrum preparation may contain both forms. The profile panel reports each separately. The "Total CBD" value, when present, combines CBD and a calculated portion of CBDA to reflect total potential CBD content. This is a reporting convention, not a measure of activation or bioavailability.

IV

Safety Screening Panels

Contaminant screening results appear alongside or following the potency panel. Each category is tested against established thresholds, and results are reported as Pass, Not Detected, or as measured values with comparison to the applicable limit. A "Pass" result means the measured value falls within the acceptable range for that contaminant. "Not Detected" means the contaminant was not found at or above the laboratory's detection limit for that method.

V

Analytical Methods

Accredited laboratories use validated analytical methods matched to the type of compound being measured. The methods section of a COA identifies which technique was used for each panel. You are not required to understand these in depth, but knowing what they do at a general level removes the opacity of encountering unfamiliar abbreviations on a document that should be easy to read.

HPLC
High-Performance Liquid Chromatography

The standard method for cannabinoid potency analysis. Separates compounds in a liquid sample by passing them through a column at high pressure, then identifies and quantifies each compound by how it responds to a detector. HPLC can measure both acidic and neutral cannabinoid forms without heat, which matters because heat destroys acidic forms like CBDA and THCA — making HPLC preferable to older gas chromatography methods for full cannabinoid profiling.

GC-MS
Gas Chromatography–Mass Spectrometry

Used primarily for residual solvent analysis. Vaporizes the sample and passes it through a column in gas form, then identifies compounds by their mass spectrum — essentially a molecular fingerprint. Exceptionally sensitive for detecting volatile compounds like ethanol and other solvents at very low concentrations. The mass spectrometry component allows positive identification of specific compounds rather than just detection of something present.

ICP-MS
Inductively Coupled Plasma–Mass Spectrometry

Used for heavy metal analysis. Converts the sample to a plasma state using extremely high-temperature ionized gas, then identifies metal elements by their atomic mass. Capable of detecting metals at parts-per-billion concentrations — the sensitivity level required for meaningful safety screening of lead, arsenic, cadmium, and mercury in botanical preparations.

What a COA Is — and Is Not

A Certificate of Analysis documents measured composition and contaminant screening results at the time of testing. It confirms what is in the preparation and that it meets established safety standards for the screened categories. It is not a therapeutic endorsement, a clinical claim, or a prediction of individual response. Its job is narrower and more precise than any of those things — and that precision is what makes it meaningful.

We provide COAs because batch-level documentation is the concrete form of what transparency means for a preparation company. Anyone can describe their process. A COA shows what the process produced, measured by an independent laboratory with no stake in the results. If you have questions about a specific document — a value that seems unexpected, a compound you don't recognize, a screening result that isn't clear — we welcome the inquiry. The documentation is meant to be read, not filed.
