Our testing and publishing standard

These are the rules we follow before a certificate or a claim about our materials appears on this site.

The rules

01
Certificates match the exact size
A certificate appears on a product page only when it covers that compound and vial size. We don’t show one size’s certificate against another, or a single compound’s certificate against a blend.
02
The method is named
Every published result states the laboratory, the analytical method and the test date, so you can judge what the figure does and doesn’t show.
03
The original report is linked
The laboratory’s PDF is linked beside every result. We copy the key figures onto the page; we don’t edit the report.
04
Doubtful results are withheld
If a result looks wrong, for example a measured content well below the label claim, we withhold the certificate and raise it with the laboratory.
05
Missing certificates are marked
Where we don’t yet hold a matching certificate, the product page says “COA on request”.
06
No undocumented claims
We don’t describe our materials as GMP, ISO or HPLC-verified unless we hold the document for that batch.

They show

An identity screen: the sample’s UV absorbance maximum matched to a reference standard.
Purity by UV/Vis spectrophotometry, against a reference standard.
Measured content in milligrams against the label claim.
Heavy metals and microbial counts, against the laboratory’s limits.

They don’t show

Chromatographic purity (HPLC), which separates related impurities.
Mass spectrometry, the more specific confirmation of identity.
A lot number printed on the report itself: the current reports refer to a flag tag on the vial.

For the difference between these methods, read how peptide purity is measured.

Research supply only: We describe materials and analytical results only, never how a product would be used.
No therapeutic claims: Studies are reported by what was observed, in which model, at what level of evidence.
Evidence stated by model: Where an article reports a study, it says whether it was in cells, animals or people.
Primary sources cited: Claims link to the published literature, with DOI or PubMed identifiers.
Regulatory status stated: Each overview states TGA, Poisons Standard and anti-doping status where relevant.
Reviewed and dated: Every article shows when it was last reviewed. Some topics are held back for legal review.
