FAQ about KLOW

How should KLOW be stored?

−20 °C, dry and protected from light; 2–8 °C after reconstitution. The storage note applies to the sealed product; see "Storage & handling" for details.

What is KLOW dissolved in in the lab?

Lyophilized peptides are usually reconstituted in the lab with bacteriostatic water (BAC water) or sterile water. Calculate the resulting concentration with our peptide calculator. We give no dosing information.

Is there a lab report for KLOW?

Yes. The current batch C207 was tested by Janoshik on 09/09/2026. Open the full report above under batches or in the lab report archive.

How fast is KLOW delivered?

We ship within 24–48 hours of payment. DHL delivers to Germany in 1–2 working days, to the rest of the EU in 2–6.

Is KLOW intended for use in humans?

No. All products are intended exclusively for research and laboratory purposes and not for use in humans or animals.

Research profile

Composition

Component	Per vial	Research focus
GHK-Cu	50 mg	Collagen formation, wound models
BPC-157	10 mg	Blood vessel formation
TB-500	10 mg	Cell migration
KPV	10 mg	NF-κB, inflammatory cytokines

The difference from GLOW

KPV corresponds to amino acids 11–13 of α-MSH and dampens inflammatory pathways in studies without affecting pigmentation, adding an inflammation-related angle to the three regeneration peptides of the GLOW blend. No studies of the four-way combination exist.

Status

No component is approved; BPC-157 and TB-500 are on the anti-doping prohibited list. Research use only.
