All products sold by Miamichem are intended for laboratory research purposes only, and are not for human or animal consumption. The products are not intended to diagnose, treat, cure, or prevent any disease, and should not be used as a food, drug, or cosmetic.

Every batch is verified for identity and purity. Batch-specific documentation, including a Certificate of Analysis (COA), is available on request after purchase — contact our research team via the Contact page. We primarily test for purity and content.

Our research peptides are supplied in lyophilized (freeze-dried) powder form to ensure maximum stability in transit. In any other format, peptide integrity would degrade more rapidly before reaching the customer.

Store in a cool, dry place away from heat, moisture, and direct sunlight. • Optimal long-term storage: below −20 °C. • Short-term storage: refrigeration at 4 °C. • Lyophilized powder tolerates brief room-temperature exposure during shipping with minimal degradation. Storage guidance is also noted on each product listing.

Lyophilized peptides typically form a solid cake. During transit the cake may break, shift, or appear uneven — this is an aesthetic issue only and does not affect quality, potency, or purity. Minor variations in color or texture can occur naturally and do not compromise the product.

Product images may display a standard vial top for illustration only. In practice, vial top colors can vary — they are used internally to help our team distinguish products during processing.
