Pure 7-OH Powder: A Buyer's Guide to Purity, COAs, and Buying by the Gram

"Pure 7-OH powder" gets searched a lot, but the phrase means very little on its own. Purity is a measurable number on a lab report, not a marketing adjective. If you're shopping for pure 7oh powder — 7-hydroxymitragynine in loose, weighable form — this guide explains what purity actually refers to, how to read a Certificate of Analysis (COA) so you can verify it yourself, and why buying 7OH powder by the gram gives you more control than pre-portioned formats. No hype, just how to read the paperwork.

What "purity" actually means for 7-OH powder

7-OH is shorthand for 7-hydroxymitragynine, a compound found only in trace amounts in the kratom plant (Mitragyna speciosa) and concentrated well beyond natural levels in modern 7-OH products. When a product is sold as isolated pure 7-oh powder, "purity" refers to the assay: the percentage of the finished powder that is confirmed by lab testing to be the named analyte, 7-hydroxymitragynine.

Two numbers on a COA get confused constantly:

  • Assay / potency — how much of the powder is 7-OH, stated as a percentage. This is the number that describes purity.
  • Total alkaloid content — the combined percentage of all alkaloids present, which can include residual mitragynine and others. A high total-alkaloid figure is not the same as a high 7-OH assay.

A powder can be "high alkaloid" and still be a low-purity 7-OH product. Always look for the assay of 7-hydroxymitragynine specifically, stated as a percentage, tied to a method (usually HPLC). If a listing advertises "pure" without a number and a document behind it, treat the word as decoration.

How to read a 7-OH powder COA, section by section

A Certificate of Analysis is a lab report tied to a specific production batch. Reading one takes about a minute once you know what each block is for. Here's the checklist we use, and the same order shown in the infographic below.

  1. Lab & accreditation. The test should come from an independent, third-party lab — not the seller's own claim. ISO/IEC 17025 accreditation means the lab's methods are formally audited. A COA on the vendor's own letterhead with no lab named is not a third-party COA.
  2. Batch / lot number and date. Every COA is tied to one lot. Match the lot number and date on the document to the lot printed on the package you receive. A COA for a different batch tells you nothing about the jar in your hand.
  3. Analyte identity. The document should name 7-hydroxymitragynine (7-OH) explicitly. "Kratom extract" or "mitragynine blend" is a different product.
  4. Assay / potency. The purity number, paired with its test method (for example, a stated percentage alongside a method such as HPLC). This is the figure that justifies the word "pure."
  5. Related alkaloids. Residual mitragynine and other alkaloids are listed here. Lower residuals generally indicate a more isolated 7-OH product.
  6. Contaminant panel. Heavy metals (lead, arsenic, cadmium, mercury), microbials (total count, E. coli, Salmonella), and residual solvents should each show a Pass against a stated limit. This is the contaminant-screening portion of the document.
  7. Signature / QR. An authorized signatory and, ideally, a scannable link back to the lab's own portal so the report can't be quietly edited.

If any of those seven blocks is missing — especially the lab name, the lot number, or the contaminant panel — you can't actually verify what you're buying. Favor'd Alkz publishes COAs for its products in a public lab-results database so you can check the lot before you order, not after.

Why buy 7-OH powder by the gram

Pre-portioned formats decide the amount for you. Loose 7oh powder sold by the gram leaves that decision with you, which is the whole point of buying powder in the first place. A few practical reasons people choose bulk powder over fixed formats:

  • You control the amount. A gram is a gram; you weigh what you want with a milligram scale rather than being locked into a manufacturer's portion.
  • Transparent per-gram math. Buying by the gram makes cost easy to compare across sellers and batches — price per gram, and 7-OH content per gram, side by side.
  • Less packaging per unit. Bulk formats typically carry less per-unit packaging than individually portioned products.

Because purity varies between products, "price per gram" only tells half the story — you also want 7-OH content per gram, which comes straight off the COA assay. A cheaper gram of a lower-purity powder isn't necessarily the better buy. Read the assay, then compare.

FAQ

What does "pure 7-OH powder" mean?
It means the powder's lab assay confirms a high percentage of 7-hydroxymitragynine specifically — not total alkaloids. The purity claim should be backed by a COA showing the assay percentage and test method.

How do I verify 7OH powder purity?
Read the Certificate of Analysis for that exact batch. Check the third-party lab name, match the lot number to your package, and confirm the 7-hydroxymitragynine assay and the contaminant panel (heavy metals, microbials, solvents) all pass.

Is buying by the gram better than pre-portioned formats?
It's a matter of control and comparison. By-the-gram powder lets you weigh your own amount and compare cost and 7-OH content per gram across products. Pre-portioned formats trade that flexibility for convenience.

What's the difference between 7-OH and mitragynine?
Both are alkaloids from the kratom plant. 7-hydroxymitragynine (7-OH) is a distinct compound; mitragynine often appears as a residual alkaloid on a 7-OH COA. A pure 7-OH powder minimizes residual mitragynine.
