Leuphasyl 200mg (Pentapeptide-18) is a cosmetic peptide powder from Peptide Sciences that mimics natural enkephalins.
Leuphasyl Research Overview
Leuphasyl is designed to act on enkephalin receptors on nerve cells, reducing neuronal excitability and neurotransmitter release. Researchers often test it together with Argireline, as the two work at different points in the signalling chain.

Using the 200mg Powder
Suitable for combination formulation studies.
Research Considerations
Combination studies of Leuphasyl with Argireline are designed to test whether acting on two separate steps of nerve signalling produces an additive effect in formulation models.
Quality Control, COA and Shipping
Peptide Sciences releases a batch only after HPLC purity and mass-spec identity testing confirm the specification. Your order ships with the matching Certificate of Analysis, packed with cold packs to protect the lyophilised material in transit.
