Leuphasyl 200mg (Pentapeptide-18)

Leuphasyl 200mg is enkephalin-mimetic peptide powder for formulation and skin model research, packed by Biotech Peptides. The price is $215, it’s in stock, and shipping is free to any country we deliver to. Every batch we sell is synthesized and lyophilized in the USA.

What is Leuphasyl?

Pentapeptide-18 is a five-amino-acid peptide (Tyr-D-Ala-Gly-Phe-Leu) modeled on the enkephalins, the body’s own short opioid peptides. Lipotec sells it under the name Leuphasyl.

It was designed to calm the nerve signal that makes facial muscles contract, and it’s usually studied next to argireline because the two work at different steps of that signal.

Leuphasyl research so far

The supplier reported that a cream with pentapeptide-18 reduced the depth of expression lines over a month, and that combining it with acetyl hexapeptide-3 gave a larger drop than either peptide alone.

These are manufacturer studies. Peer-reviewed independent trials are limited, so most labs use it as a mechanism comparator in nerve and muscle cell models.

The full list of Leuphasyl papers is on PubMed, and most abstracts are free to read.

Leuphasyl mechanism of action

Enkephalins bind receptors on nerve endings and make the neuron less excitable. Pentapeptide-18 copies that action, so less acetylcholine is released toward the muscle.

Argireline works further down the line by interfering with the SNARE complex that packages acetylcholine for release. Because the two act at separate points, researchers combine them to look for additive effects.

Working with Leuphasyl 200mg

Measure portions with a clean, dry spatula and keep the rest sealed. A small sachet of desiccant in the storage bag helps.

Most cosmetic peptides dissolve in water or in the water phase of a formula. Add them below about 40°C, after the hot steps, so heat doesn’t damage the chain.

Keep the unopened powder frozen. Once you’re working from it, the fridge and a tight seal are enough for a month or so.

Research models for Leuphasyl 200mg

Most published work on peptides like this runs in two stages: cell assays that measure one output, then a cream or serum test on skin explants or volunteers measured by imaging.

Because formulation levels are small, 200mg covers many test batches. Split it into a few sealed portions on day one and only open one at a time.
