FAQ

Yes. This is normal. Lyophilized peptides can shift, fracture, or separate during shipping and handling. If the vial cap is intact and the seal has not been punctured, the product is considered uncompromised.

Lyophilized peptides are measured by mass, not liquid volume. The visible amount of powder in a vial can vary and does not indicate underfilling.

Physical appearance can vary with the compound and the lyophilization process. Appearance does not affect peptide identity or integrity.

No. If there is moisture or liquid inside a sealed vial, please email support@bionetiklabs.com.

Both peptides and Reconstitution Water should be at room temperature before reconstitution.

All of our peptides are sold in lyophilized form, meaning the liquid has been removed to extend shelf life. Store lyophilized peptides in the refrigerator. They can also be kept in the freezer, where they typically last one to two years, depending on the storage temperature.

Once reconstituted, peptides should be kept in the refrigerator only. Do not store reconstituted peptides in the freezer. Make sure your refrigerator is not set too cold, or the peptide may gel or freeze.

Short-term temperature exposure during shipping is generally not an issue for sealed, lyophilized peptides. Repeated temperature  cycling should be avoided once received.

Some peptides can be sensitive to prolonged light exposure. For best stability, store vials away from direct light.

Yes. Every peptide batch is tested before it ships by Freedom Diagnostics, an independent U.S. laboratory in Franklin, Tennessee. They have no affiliation with us and no stake in the result. Every vial carries a QR code that opens the certificate for that exact batch on the lab’s own website. You can match your vial to it by lot number, cap color and crimp ring color, and check the purity and net content printed on your label against the results on the certificate. How to verify your vial.

Every peptide batch is tested by Freedom Diagnostics in Franklin, Tennessee, an independent U.S. laboratory operating to ISO 9001 quality management and Good Laboratory Practice principles. In their own words: “No vendor affiliations. No conflicts of interest.”

Why the certificates are on our site: the PDFs on our Test Results page are Freedom’s own certificates, posted so you can read them before you order. They’re for browsing. Verification happens at the lab.

The fastest way to verify: scan the QR code on your vial. It opens the certificate for that exact batch on Freedom’s own site. That QR code is Freedom’s, not ours. It’s generated by the lab and printed on their certificate, and we print the same code on the vial.

To browse everything we’ve ever had tested: go to freedomdiagnosticstesting.com and click COA Lookup. Use the Company Name box (the second box, not the first), enter Bionetik Labs, and search. To find one specific certificate, use the first box with the Search Code from the top right of your COA.

Altered certificates are a known problem in this industry. A COA hosted on a seller’s own website can be edited. One on the lab’s website can’t.

Every new peptide batch is now 8X tested: five vials from each batch go through an 8-point test panel:

• Purity (HPLC): measures how pure your sample is, reported as a percentage.
• Identity (LC-MS): confirms by molecular mass that the compound is what the label says.
• Net Content: measures how much peptide is actually in the vial.
• Endotoxins: screens for bacterial endotoxin contamination.
• Sterility (PCR): screens for microbial contamination using PCR.
• Conformity: tests additional vials from the same lot to confirm they match.
• Heavy Metals: screens for heavy-metal contamination.
• Contaminant Screen: screens for harmful contaminants.

Descriptions are Freedom Diagnostics’ own. Check the certificate for your lot to see exactly what it was tested for. Reconstitution Water is tested separately by Kovera Labs for preservative content, pH, endotoxins and sterility.

Yes. Every batch of our Reconstitution Water is tested before it ships, and its certificate is posted on our Test Results page, with the testing lab named on it.

Five vials are taken from every new batch and tested before it ships. The same full panel is run every time, regardless of batch size. A batch that doesn’t pass is never shipped. It’s discarded.

A certificate can include peptide identity, purity results, net content, endotoxin and sterility screening, batch or lot information, a photo of the tested vial, and the analytical methods used.

The number of vials on your certificate depends on the testing performed. Some tests require more than one vial, and our conformity testing checks additional vials from the same lot to confirm they match. Seeing a result for each vial shows the batch is consistent, rather than relying on a single sample.

We are not able to interpret laboratory data or provide conclusions beyond what is stated on the certificate.
