Use-level and cost considerations The four peptides have substantially different per-mg pricing and therefore different finished-product cost contributions at typical use levels: Matrixyl at 5% use level in a finished serum represents about $5-15 of peptide cost per 30 mL bottle (depending on volume procurement scale) Snap-8 at 7% use level: about $2-8 per 30 mL bottle GHK-Cu at 1% use level: about $0.50-2 per 30 mL bottle (lowest per-finished-unit because the use level is much lower) AHK-Cu at 0.5% use level: about $0.30-1.50 per 30 mL bottle For premium-positioned multi-active products, brands typically combine GHK-Cu + Matrixyl + Snap-8 in a single formulation

Most of these huwentoxins (HWTX) contain 3040 amino acids with three disulfide bonds and adopt an inhibitor cystine-knot (ICK) motif in their three dimensional structure, except for huwentoxin-II (HWTX-II) which adopts a novel scaffold different from the ICK motif
