Purity analysis is primarily performed using high-performance liquid chromatography (HPLC). Mass spectrometry (MS) is available for some products for molecular weight confirmation.

We usually offer packaging in 1mg, 5mg, 10mg, 25mg, 50mg, 100mg, and larger quantities. Specific sizes can be customized according to customer requirements.

After dissolution, it is recommended to aliquot into single-use doses and store at -20℃ or -80℃, avoiding repeated freeze-thaw cycles. Most peptide solutions are stable for several hours to several days at 2-8℃; long-term refrigeration is not recommended.

We specialize in a variety of high-purity peptides, including custom peptides, research-grade peptides cosmetic peptides, and
peptide lyophilized powders and raw materials for pharmaceutical applications.

Our peptides are typically >99.5% pure, and we provide detailed COA (Certificate of Analysis)

Our lyophilized peptides require reconstitution before theyre viable for research use. This involves adding a liquid (Bac Water.
Saline, Distilled Water..).
Any amount of liquid can be used. If you add 1ml (1ml equals 100 units) every 10 units will contain 1mg of peptide.
Once reconstituted peptides should be stored refrigerated.
