Our commitment
Pepreva’sTesting Standard
We believe “tested” should mean more than a purity number.
Every Pepreva batch is independently evaluated through an 8-point Full QC Panel by a third-party laboratory, creating a much more complete analytical picture of the compound than HPLC purity alone.

8 tests. One traceable batch.Full documentation.
Because 99% purity is one result.
We wanted the bigger picture.
Our 8-PointFull QC Panel
Eight analyses look beyond a single purity number — examining identity, quantity and key contaminants in the tested sample.
02 · Purity
HPLC analysis measures target peptide purity and identifies peptide-related impurities.
03 · Net Peptide Content
Confirms molecular identity using LC-MS analysis.
04 · Identity
Analytical testing confirms the identity of the compound being tested.
05 · Heavy Metals
ICP-MS analysis screens for potentially harmful elemental contaminants.
06 · Sterility
PCR-based microbial testing evaluates the sample for detectable microbial contamination.
07 · Endotoxin
USP <85> testing evaluates bacterial endotoxin levels.
08 · Fentanyl Screen
Immunoassay screening specifically checks the sample for fentanyl.
Together, these eight analyses examine what the compound is, how pure it is, how much is actually present, and whether important contaminants are detected.
