What is tripeptide-1 (GHK Basic)?
Tripeptide-1 is the INCI name for GHK, the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys), supplied here without a copper ion. GHK occurs naturally in human plasma, where it binds copper to form GHK-Cu. The copper-free form lets researchers and formulators study the peptide on its own.
Product specifications
- Compound: GHK (tripeptide-1), copper-free
- Sequence: Gly-His-Lys (3 amino acids)
- Molecular weight (free peptide): about 340.4 g/mol
- Sizes: 50mg or 200mg
Available sizes: 50mg and 200mg
GHK Basic is offered in two sizes, 50mg and 200mg. Both contain the same compound at the same grade. The figure is the total amount of peptide supplied as a dry powder; it is not a concentration. A concentration only exists once the powder is dissolved, and it depends on how much solvent the lab or formulator uses.
- 50mg: suited to small test batches and early formulation or bench work.
- 200mg: four times the material, for larger formulation runs or repeated experiments from one batch.
