What independent testing cannot tell you.

The honest limits of any single laboratory result, including ours.

One sample, one moment

A test describes the sample that was tested. It does not establish the quality of other products, other lots, or future purchases from the same vendor.

Only what was measured

Source Standard testing covers identity and RP-HPLC area purity for eligible individual peptides. It does not cover:

  • Sterility or endotoxins.
  • Heavy metals or residual solvents.
  • The amount of peptide in a vial.
  • Blends, sprays, capsules, creams, or dissolvable strips.

Not a safety or use statement

Results are analytical findings on products sold for research use only. They are not approvals, endorsements, or guidance on safety, dosing, or human or animal use. Reading results over time, alongside the testing history on a profile, gives a fuller picture than any single test.

A result describes one sample, tested by specific methods, at one point in time.
