Trend chart unlocks once we have price snapshots from more than one day. ## Price History 2 data points - Ion Peptide - Disguised Alpha ### Acetyl Hexapeptide-8: potential benefits - Targets dynamic expression wrinkles - forehead, glabellar, and periorbital (crow's feet) lines - Proposed to reduce facial neuromuscular signaling by destabilizing the ternary SNARE complex (acts as a SNAP-25 N-terminal mimic) - A randomized, placebo-controlled human study reported ~49% subjective improvement in periorbital wrinkles vs 0% for placebo over 4 weeks (small evidence base) [PMID: 23417317] - Marketed as a topical 'Botox alternative' - reversible mechanism, not a neurotoxin, with no botulinum-type systemic risk - Supplied as a raw cosmetic-compounding powder for research/formulation use (verify purity via HPLC COA) - Commonly combined with related peptides (e.g., Acetyl Octapeptide-3 / Snap-8) in anti-wrinkle formulations ### AHK-Cu: potential benefits - Hair follicle stimulation — activates anagen phase via Wnt/β-catenin in dermal papilla cells - Reduction of follicle miniaturization in androgenetic alopecia models - Enhanced scalp vascularity via VEGF upregulation - Wound healing acceleration — copper cofactor for lysyl oxidase and collagen maturation - Synergistic with GHK-Cu in multi-peptide scalp formulations ## Frequently asked ### What's the difference between Acetyl Hexapeptide-8 and AHK-Cu? Acetyl Hexapeptide-8 is a skin & hair that acetyl hexapeptide-8 (argireline) is patterned after the n-terminal domain of snap-25 and behaves as a competitive mimic of that protein during snare complex assembly. the snare…. AHK-Cu is a skin & hair that ahk-cu delivers bioavailable copper ions to follicular and dermal tissues. copper acts as a cofactor for lysyl oxidase (collagen/elastin crosslinking), superoxide dismutase…. The two differ in mechanism, half-life (Short (topical application, no systemic absorption at cosmetic doses) vs Unknown (topical half-life, follicular retention not well characterized)), and typical dose range. ### Which has the longer half-life, Acetyl Hexapeptide-8 or AHK-Cu? Acetyl Hexapeptide-8 has a half-life of Short (topical application, no systemic absorption at cosmetic doses). AHK-Cu has a half-life of Unknown (topical half-life, follicular retention not well characterized). Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, Acetyl Hexapeptide-8 or AHK-Cu? Lowest listed price on BodyHackGuide: Acetyl Hexapeptide-8 from $129.00, AHK-Cu from $44.99. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers. ### Can you stack Acetyl Hexapeptide-8 and AHK-Cu? Stacking depends on mechanism overlap, safety profile, and goals. Acetyl Hexapeptide-8 and AHK-Cu should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
