All MirinMaxxed products are sold strictly for in-vitro laboratory research use. They are not medicines, have not been evaluated by the TGA, FDA, or any equivalent regulator, and are not intended for human or animal use of any kind. This labeling reflects both their actual regulatory status and our own policy — not a technicality.

Every product on this site has a corresponding Certificate of Analysis. Where a batch's lab results are still being finalized, the COA is honestly marked "Pending" rather than left blank or assumed — check the COA page for the current status of any product.

No. We don't provide reconstitution guidelines, dosing suggestions, or medical guidance of any kind. These products are sold for use by qualified research professionals. If you need medical advice, please consult a healthcare professional.

No. If an item you've ordered becomes unavailable, we'll contact you directly rather than substitute it with something else.

Lyophilized (freeze-dried) peptides often form a loose, flaky, or clumped cake rather than a fine powder. This is a normal result of the freeze-drying process, not a sign of degradation.

Some peptides are denser or more hydrophobic than others and take longer to fully dissolve. Adding the diluent slowly down the side of the vial and gently swirling — never shaking — usually helps.

Store lyophilized (unreconstituted) peptides frozen and protected from light. Once reconstituted, refrigerate and use within the timeframe noted on that product's page — exact storage details vary slightly by peptide and are listed there.

Lyophilized means freeze-dried. The water has been removed from the peptide under vacuum at low temperature, leaving a stable solid that's reconstituted with a diluent — such as bacteriostatic water — before use.

Check our Certificates of Analysis page. We publish batch-level testing results there as soon as they're available; until then, a product is honestly shown as "Pending" rather than given an unearned status.

No. Our products are sold exclusively for in-vitro laboratory research and are not for human or animal consumption of any kind.
