Argireline vs Snap-8

Argireline vs Snap-8 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Argireline
Cosmetic & Skin Peptides

Argireline (acetyl hexapeptide-3, brand name Argireline from Lipotec/Lubrizol) is a synthetic acetylated hexapeptide derived from the N-terminal fragment of SNAP-25 (synaptosomal-associated protein 25), a component of the SNARE complex required for neurotransmitter vesicle fusion...

Snap-8
Cosmetic & Skin Peptides

Snap-8 (Acetyl Octapeptide-3) is a synthetic cosmetic peptide that extends the pharmacophore of Argireline (Acetyl Hexapeptide-3) by two additional amino acids at the C-terminus. Both peptides mimic fragments of SNAP-25 (synaptosomal-associated protein 25), a key component of the...
