Lab Testing & Verification

Where our testing stands

These are the Certificates of Analysis we have commissioned ourselves. Each report names Portal to Wellness as the client and links to the report on the laboratory’s own site, so you can check it independently.

More results are added to this table as each report is issued.

Our reports are also listed on BatchGuild, an independent registry of laboratory certificates: View our COA records on BatchGuild →

What changed, and why

Until recently this page listed 13 Certificates of Analysis from Janoshik Analytical, each with a verification key. We have removed them. Here is the honest reason.

Those COAs were submitted to the lab by our supplier, not by us. Two problems follow from that. First, a supplier-submitted COA proves a sample passed testing — it does not prove the sample came from the same lot that shipped to you. Second, and more importantly: Janoshik’s verification portal requires both a task number and a unique key. We only ever held the keys. That means neither we nor you could actually complete a verification.

A verification key you cannot verify is not evidence. Publishing it implied a level of proof we could not deliver, so it has come down.

What we are doing instead

We now commission our own testing from Janoshik Analytical, an independent laboratory. Samples are pulled from our own stock, shipped by us and paid for by us. Our first round of three samples was submitted on 30 September 2026, and results are added to the table above as each report is issued. Each published entry carries:

• The compound and exact presentation, matching the product you can buy
• The batch number printed on the vial
• A link to the full report on the laboratory’s own verification site
• The laboratory’s task number, so the check actually works
• A clear PTW-submitted label

We intend to publish results that fail as well as results that pass, and not to sell material that misses the standard below. That standard is what we are committing to as this programme gets under way.

This page updates as each new report arrives.

The standard we are committing to

This is how we act on results. We revised this standard on 13 October 2026, when our first BPC-157 10mg batch tested at 97.035% purity. The earlier version (sell at 99% or higher, review 98–98.9%, do not sell below 98%) would have kept that batch off sale. We chose to sell it with its exact result published on the product page rather than hold it back, and the table below now reflects that. We revised it again on 23 October 2026, when our HGH 24IU batch tested at 93.151% purity, with more than the labelled amount (30.36 IU in a 24 IU vial). The previous wording would have kept that batch off sale. We are keeping it on sale with its exact result published on the product page while we work with the supplier on it, and the table below now says so.

Wellness supplements

Our supplement line comes from a separate contract manufacturer and its documentation is independently published by them, so this section is unaffected by the above. Testing and certification status differs by product, so we list it per item. Certificates of Analysis are available on request.

Note: the FDA does not approve dietary supplements. “FDA-registered facility” means the manufacturing site is registered with the FDA — not that any product has been reviewed or endorsed.

Questions

If you want to know the current testing status of a specific compound before you order, ask us. We will tell you plainly whether it has been tested, when, and by whom.

Compounds we are asked about most often have their testing status stated on their own page — see BPC-157 formats, specifications and testing status.

If you want the testing status of a compound we do not stock, ask us to source it — we will tell you whether it can be obtained before anything else.

All products are sold for research and identification purposes only. Not for human dosing, injection, or ingestion.
