Two tripeptides that could not look less alike in the vial: GHK-Cu is a blue copper complex whose certificate carries a copper assay, KPV is a plain white acetate salt of lysine-proline-valine. Masses 403.9 for the complex and 342.4. Both elute at the front of a C18 gradient. GHK-Cu is sold in 50 and 100 mg vials, which is why its per-milligram price is among the lowest on the list; KPV comes in 5 and 10 mg vials at a conventional per-milligram figure.

Questions
Which is cheaper per mg, GHK-Cu or KPV (lysine-proline-valine)?
GHK-Cu, at $0.036 per mg for its best-priced strength (CU100) against $0.519 per mg for KPV (lysine-proline-valine) (KPV10), 93 percent less. Compare at the vial size you will actually use; the gap changes with strength.
Which comes in more strengths?
Both are offered in 2 strengths. Every strength is a separate line with its own code, price and stock state.
Can GHK-Cu and KPV (lysine-proline-valine) go in one order?
Yes. Any lines can share an order; the minimum is $300 of goods per order, or $100 on a first order, and one sealed box of ten per line. Lines on the shelf ship in 1 to 2 business days; made-to-order lines follow in about two weeks, at no extra freight.
Are they tested to the same specification?
Yes: purity not less than 98.0 percent by RP-HPLC, identity by mass, water content, net content within 5 percent of label, and a retest date, with a certificate of analysis per batch. What differs is what each certificate has to look for, which is set by the molecule and described on each compound’s own page.
