Why this pen
Four research peptides in one pre-combined cartridge: the GLOW base of GHK-Cu, BPC-157 and TB-500, extended with KPV for melanocortin-linked signalling work. One order covers a four-pathway study design without four separate reconstitutions.
The three-peptide base is available as the GLOW Pen, and the two-peptide base as the WOLVERINE Pen.

Cold chain
How we ship it
Every pre-filled pen leaves us cold and arrives in a plain box. Refrigerate on arrival at 2 to 8 °C.
Chilled
Frozen gel packs inside a sealed foil pouch hold temperature for roughly seven days in transit.
Insulated
The pouch sits inside a wool-lined envelope, so the cold chain survives a normal courier journey.
Discreet
Plain outer box with no branding and nothing on the label that names the contents.
Tracked delivery
Prepared and dispatched by our team within 1 to 2 working days.

What is in the KLOW cartridge
KLOW is the supplier name for a four-peptide research set: the GLOW blend of GHK-Cu, BPC-157 and TB-500, plus KPV. The K stands for KPV. What you are buying is defined by the four components and the mass of each, all of which are printed on the label. Ours is supplied pre-mixed in a sealed 3ml cartridge inside the Celyfe precision pen.
Why add KPV
KPV is the lysine-proline-valine tripeptide at the C-terminus of alpha-MSH. Researchers use the three-residue fragment instead of the whole hormone because it retains the sequence studied in inflammatory-signalling models while dropping the melanocortin-receptor pharmacology of the full peptide. In a four-compound set it acts as a probe for a pathway family the other three do not cover.
KLOW vs GLOW vs WOLVERINE
- WOLVERINE - BPC-157 (15mg) and TB-500 (15mg). Two peptides, 30mg.
- GLOW - the same two plus GHK-Cu (75mg). Three peptides, 105mg.
- KLOW - GLOW plus KPV (15mg). Four peptides, 120mg.
Storage and handling
- Refrigerate at 2 to 8 °C as soon as the parcel arrives; keep the cartridge sealed and protected from light.
- Do not freeze. Freeze-thaw cycling damages peptides already in solution.
- Dilute into a near-neutral buffer rather than an acid to preserve the copper complex.
- Check the batch certificate for the recorded appearance and the storage window for that lot.
