About this compound
The manufacturer tests each peptide in every batch of our KLOW blend by HPLC and mass spectrometry, to ≥99% purity. Those certificates are confidential under our supply agreement, so we cannot share them. Separately, we send selected batches to Janoshik, an independent lab, and publish every report on our lab reports page. Not every batch has an independent report, and each report names the batch it covers.
KLOW is supplied as a lyophilised powder in a single sealed vial containing 80 mg of total peptide (BPC-157 10 mg, GHK-Cu 50 mg, TB-500 10 mg, KPV 10 mg). Prior to dispatch it is stored at −20°C. On receipt it can be kept in a refrigerator at 8°C or below, which will keep it stable for several months. For longer-term storage, keep it at −20°C, which allows storage for several years without affecting the compounds’ structure or purity.
Yes. All UK orders are dispatched via Royal Mail 24-Hour Tracked & Recorded. In-stock orders placed before 3pm are shipped the same day.
KLOW is also known as the KLOW blend, GLOW+KPV, and BPC-157/GHK-Cu/TB-500/KPV blend. It is the GLOW blend with KPV added as a fourth component.

The difference is measurable
Simply Peptides vs. typical UK suppliers
Most suppliers ask you to take their word for it. We publish the reports, the batch numbers and our real delivery times — so you don't have to.
| What matters | Simply Peptides | Typical UK suppliers |
|---|---|---|
| Purity testing | Selected, vetted manufacturers confirm ≥99% purity by HPLC and mass spectrometry, every batch | Self-reported purity, or one method quoted with no figure attached |
| Independent testing | Third-party Janoshik analysis on selected batches — every report published and verifiable | In-house or supplier-supplied paperwork you have no way to check |
| Storage before dispatch | Held at −20°C right up to the day it ships | Room-temperature shelf storage, or simply not stated |
| Dispatch | Order by 3pm on a working day and it is with Royal Mail the same day — 100% hit rate, measured | “Same-day dispatch” claimed, with nothing published to back it |
| Delivery performance | Published and rebuilt nightly from every single order — 77% arrive the next working day | No delivery performance figures published at all |
| Delivery cost | Free Royal Mail Tracked 24 over £20, tracked from dispatch to the door | A shipping fee on every order, however much you spend |
