OUR TESTING PROCESS

Eight Steps Behind Every Batch

Independent Batch Verification

Every batch of Puratek research peptides goes through eight steps, from raw material to sealed vial, so you know exactly what you’re getting: verified purity, identity, and consistency.

01

Purity

Confirms the purity level of the tested batch.

02

Identification

Verifies the identity of the research material.
03

Net Content

Confirms the amount of material contained in each vial.
04

Endotoxins

Screens the batch for bacterial endotoxin contamination.
05

Sterility

Evaluates the sample for microbial contamination.
06

Heavy Metals

Screens for specified heavy-metal contaminants.
07

Conformity

Checks the tested material against defined batch specifications.
08

Fentanyl Screening

Screens the tested sample for fentanyl contamination.

OUR PURITY PROMISE

Guaranteed 99% Pure Or Your Money Back

Every batch of Puratek research peptides is guaranteed to be at least 99% pure. Not “usually,” not “most of the time.” Every batch. If your own lab testing shows a batch falls below 99%, contact us for a full refund. Your research deserves accountability, not empty promises.

Every batch is third-party tested, with a certificate of analysis (COA) you can check before you buy.
