Acu Aminos supplies lyophilized research peptides for laboratory and in-vitro studies. Our catalog covers growth-hormone secretagogues such as Ipamorelin, incretin-class peptides including Tirzepatide and Retatrutide, tissue-signaling peptides like Thymosin Beta-4 (TB-500), GHK-Cu and KPV, neuro- and immuno-active peptides such as Pinealon, VIP, Thymosin Alpha-1 and Kisspeptin-10, and the tripeptide antioxidant Glutathione.
Each product is synthesized by solid-phase peptide synthesis, purified to a minimum of 99% by reverse-phase HPLC, identity-confirmed by mass spectrometry, and sealed in a sterile glass vial. Every product has a downloadable COA in our library. All products are strictly for research use only and are not intended for human or veterinary use.
What are research peptides?
Structure
Peptides are chains of amino acids joined by amide (peptide) bonds. Short chains of 2 to roughly 50 residues are called peptides; longer chains fold into proteins. Sequence, chain length and terminal modifications define how a peptide behaves.
Synthesis & purity
Research peptides are built by solid-phase peptide synthesis, cleaved from the resin, purified by reverse-phase HPLC and lyophilized to a stable powder. Purity is reported as the HPLC area percentage of the target peak; identity is confirmed by mass spectrometry.
Laboratory use
In the lab, peptides serve as receptor ligands, enzyme substrates, signaling probes and reference standards in cell-culture, biochemical and analytical studies. Our products are supplied exclusively for these in-vitro research applications.
Handling & storage
Lyophilized peptides should be kept sealed, protected from light and moisture, and stored refrigerated or frozen for long-term stability. Allow vials to reach room temperature before opening to prevent condensation.
