The complete repair and renewal stack in one pen. Four peptides, one pre-mixed system, built to cover healing, skin and inflammation at the same time.
Why KLOW
KLOW layers GHK-Cu for skin, collagen and remodelling, TB-500 for systemic recovery and cell migration, BPC-157 for targeted tissue and gut repair, and KPV for its calming, anti-inflammatory signal. Four peptides that usually mean four vials and four separate mixes now live in a single pre-filled pen.
Why a pre-filled pen
Everything a vial makes you do, the pen has already done for you.
- No reconstituting. It arrives as a liquid, already mixed. No bacteriostatic water, no swirling, no waiting.
- No mixing maths. The concentration is set at manufacture, so every click delivers the same measured dose.
- Up to 12 months of shelf life. Made as a liquid, it stays stable far longer than a powder you reconstitute yourself.
- Microdose without a clock. Cycle on and off at your own pace instead of racing a 35-day window.
- Travel-ready and discreet. One sealed pen, nothing to prepare, nothing to spill.
Pre-mixed liquid vs lyophilised powder
The whole difference comes down to one thing: when the clock starts.
Lyophilised powder
The clock starts when you mix
~35 daysof use once reconstituted
- You reconstitute it yourself, then the countdown begins.
- Potency starts slipping within weeks of mixing.
- Use it fast or waste it, with no room to cycle on and off.
Valar pre-filled liquid
It was never a powder
up to 12 monthsshelf life, manufactured as a liquid
- Made in liquid form, stable far longer than reconstituted powder.
- The same reason a pharmacy can hold a GLP-1 pen like Mounjaro for up to a year.
- Microdose on your terms, with no 35-day clock ticking.
Simple from the first dose
Preparation
None. Already mixed and ready. Nothing to reconstitute, draw up or measure.
On your terms
Because this pen can last up to a year, you can microdose on and off without the time pressure of a freshly mixed vial.
Storage
Manufactured at room temperature as a liquid. Once you take your first dose, keep the pen refrigerated.
Pen needles
Sold separately. Each pen is multi-dose, for single-patient use, subcutaneous only.
Dosing, in clicks
Your pen works like a standard dosing pen: you turn the dial and count the clicks, where one click is one unit and one unit delivers 0.01 mL. Prime the pen, dial your dose in clicks, and inject subcutaneously.
Starter dose
10 units (0.1 mL) per day. A simple starting point, no titration required.
One click
1 unit on the dial = 0.01 mL.
Your clicks per dose
Printed on the batch card inside your pen, matched to its exact fill.
Same tested batch as our vials.Each pen is filled from freshly tested material. A certificate of analysis for your batch is available on request.
