UK Launch · The Ped Shop Exclusive

A new name in research peptides, landing in the UK

SerenQ Pharmaceuticals builds research peptides into sealed, pre-filled injection pens rather than lyophilised vials. No reconstitution, no bacteriostatic water, no guesswork with a syringe barrel. Dial the units you need, read them off the window, done.

SerenQ has appointed

The Ped Shop as its exclusive UK stockist

. Every pen sold here comes direct from the manufacturer, in sealed retail cartons, with a unique serial number and QR authenticity code on the label.

About PT-141

PT-141, also called bremelanotide, is a synthetic seven amino acid peptide derived from melanotan II. It was originally investigated as a tanning agent, and the sexual arousal effects that dominate the literature today were first recorded as an unexpected finding during those early trials.

That distinction is the reason it appears in the literature on hypoactive sexual desire disorder in women, where a vasodilator has nothing to act on. Bremelanotide holds an FDA approval in the United States under the brand name Vyleesi for that specific indication, administered by autoinjector. It has no UK medicines licence, and the material supplied here is not that product.

Where the evidence sits:

bremelanotide has been through human trials and carries a US approval for one narrow indication in premenopausal women. That is a far stronger evidence base than most peptides on this site, but it does not extend to the doses, routes or populations people typically discuss, and the material here holds no UK medicines licence.

The pen format

PT-141 is one of the compounds where dose control matters most, because the gap between a research dose and the dose that causes nausea and flushing is narrow. A dial in 50mcg steps makes that gap navigable in a way a 100 unit insulin syringe does not.

10.00mg of PT-141

per pen, in solution and ready to use

1 unit = 50mcg.

10 units on the dial gives 500mcg

200 units in total

, which works out at 20 full 500mcg draws per pen

– Dial and dose window let you set the exact amount and read it back before dispensing

– 4 screw on pen tips supplied, individually sealed,

32G 0.23 x 4mm

– Protective cap, clip and a rigid retail carton for storage and transport

– Batch number, expiry and serial printed directly on the pen barrel, not just the box

Handling and storage

– Store refrigerated at 2 to 8°C. Do not freeze

– Keep in the outer carton, away from direct light

– Short periods at room temperature during transit are expected and normal

– Use a fresh sealed tip for each dispense and dispose of tips in a sharps container

– Expiry 12/2027 on sealed, correctly stored stock

Choosing between PT-141, MT2 and the ED orals

These three get grouped together and they should not be.

Sildenafil

are PDE5 inhibitors: they work on blood flow, and they do nothing at all for interest. PT-141 is the mirror image, acting centrally on desire and doing nothing for the vasculature. If the issue is mechanical, a PDE5 inhibitor is the relevant compound. If the mechanism works but the interest is not there, it is not.

MT2

is the closer relative, and shares the melanocortin mechanism, which is why libido effects show up in MT2 reports as a side effect rather than the point. MT2 is selected for pigmentation; PT-141 has had the tanning activity largely bred out of it. Running MT2 for libido means accepting tanning you may not want, and running PT-141 for a tan will not work.

Guides that go deeper:

PT-141 (Bremelanotide): desire, not blood flow

Sildenafil vs tadalafil, and why ED appears on cycle

Melanotan 2 (MT2): what it does and what it costs you
