Research & Specialized Peptides
Some compounds do not sit neatly in a single research category, and this is where we keep them. It currently holds GHK-Cu and AHK-Cu, the two copper tripeptide complexes in our catalogue, alongside KPV 10mg and the mitochondria-targeted SS-31. GHK-Cu is also stocked in 50mg and 100mg ten-vial kits for larger protocols.
Whatever the mechanism being studied, the sourcing standard does not change: GMP-certified manufacture in the United States, 99%+ purity verified by high-performance liquid chromatography, identity by mass spectrometry, and endotoxin plus heavy-metal testing on every lot. The resulting Certificate of Analysis is published in our testing library and tied to the batch you receive. All items here are supplied for research use only; they are not approved for human or animal use.

SS-31 is a laboratory research peptide used to study mitochondrial membrane interactions, cardiolipin binding, and cellular signaling pathways in controlled experimental systems. This product is supplied strictly for research use only. It is not approved or intended for human or animal use, and any discussion of biological activity refers only to preclinical or in vitro research. One of the unique aspects of SS-31 is its specific affinity for cardiolipin, a phospholipid located within the inner mitochondrial membrane that is essential for maintaining electron transport chain structure and membrane integrity. Disturbances in cardiolipin stability are commonly examined in research involving oxidative stress, mitochondrial dysfunction, and bioenergetic decline. SS-31’s ability to interact with cardiolipin has therefore made it a recurring subject in studies investigating how mitochondrial membrane condition affects broader cellular behavior. Additionally, research has documented that SS-31 may influence the production of reactive oxygen species (ROS) at the mitochondrial level. Excessive ROS production is commonly evaluated in studies on cellular stress, inflammation, and mitochondrial impairment. By focusing on mitochondria directly, rather than acting as a broad-spectrum antioxidant, SS-31 offers researchers a pathway to study targeted mechanisms of oxidative modulation rather than systemic antioxidant activity. For laboratory use, SS-31 is commonly supplied as a high-purity, LPS-free peptide, manufactured to meet strict research standards. As an endotoxin-free peptide, it is frequently utilized in sensitive in vitro and ex vivo experimental setups where contamination control is critical. Research peptides such as SS-31 are typically endotoxin tested to support reproducibility and reliability across mitochondrial and cellular research applications. This compound is intended strictly for research use only and is not approved for human or animal use. -

KPV is a synthetic peptide that’s made up of three amino acids: Lys-Pro-Val. These three amino acids are the C-terminal fragment (position 11-13) of the alpha-melanocyte-stimulating hormone (α-MSH), which is a naturally occurring melanocortin peptide that’s involved in the regulation of inflammation and immune responses. Researchers use the KPV peptide to study inflammatory signaling, epithelial biology, and communication pathways within the immune system.Licensed Peptides KPV Product Specifications

AHK-Cu is a synthetic copper-associated tripeptide consisting of three amino acids—alanine, histidine, and lysine—that form a complex with a copper ion. It is commonly identified in research literature as AHK-Cu or Copper Tripeptide-3. In contrast to GHK-Cu (Copper Tripeptide-1), a naturally occurring copper-binding peptide that has been detected in biological fluids such as plasma, saliva, and urine, AHK-Cu is a synthetically produced peptide developed for experimental research. Its alanine–histidine–lysine sequence has been investigated for its interactions with cellular signaling pathways, particularly those associated with dermal papilla cell activity, hair follicle biology, and cellular survival mechanisms. Preclinical research has explored its potential effects on follicular tissue and related signaling processes, although these findings remain primarily based on laboratory and ex-vivo studies.
