How we ship it
Every pre-mixed vial leaves the UK cold and arrives in a plain box. Refrigerate on arrival at 2–8 °C.

Chilled
Vials travel with frozen gel packs inside a sealed foil pouch, which holds 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.
Same-day dispatch
Order before 3pm GMT, Monday to Friday.
Free over £100
Tracked UK delivery, next working day.
2–8 °C on arrival
Refrigerate as soon as the parcel lands.

Klow Stack: research FAQs
- What is Klow Stack?
- Klow Stack is a four-compound research set containing the peptides GHK-Cu (50mg), KPV (10mg), BPC-157 (10mg) and TB-500 (10mg), for a total of 80mg. These are short synthetic peptide sequences from families studied in laboratory research, including a copper-binding tripeptide (GHK-Cu), a tripeptide fragment of alpha-melanocyte-stimulating hormone (KPV), and two peptide fragments (BPC-157 and TB-500). It is labelled strictly for in-vitro laboratory research use only.
- What is Klow Stack studied for in research?
- The individual peptides in this set have been investigated in preclinical and cell-based laboratory research across several distinct signalling pathways. Published laboratory work has studied GHK-Cu and BPC-157 in tissue and cellular models, examined KPV as a C-terminal alpha-MSH fragment in in-vitro work relating to inflammatory signalling pathways, and studied TB-500 in cell-based models. Grouping the peptides allows a laboratory to investigate several sequences acting on different pathways within a single research set. These are in-vitro and preclinical research observations only and are not established effects in humans or animals.
- Is Klow Stack legal to buy in the UK?
- Yes. The compounds in Klow Stack are legal to purchase and possess in the UK for laboratory research purposes. They are not licensed medicines and cannot be sold for human or veterinary consumption, and every order ships labelled for in-vitro research use only.
- What purity is your Klow Stack, and is it lab-tested?
- The peptides in Klow Stack are verified to 99%+ purity by HPLC analysis. The purity figure printed on each batch's Certificate of Analysis is the actual value recorded in the laboratory for that batch, not a generic marketing claim. Each set is synthesised and dispatched from our own UK facility.
- Does Klow Stack come with a Certificate of Analysis?
- Yes. A batch-specific Certificate of Analysis (COA) ships with every order, documenting the recorded purity for the exact batch supplied. Sample COAs can also be viewed in our COA library before you buy, so you can review the format and testing detail in advance.
- What compounds are in the Klow Stack, and why are they grouped together for research?
- Klow Stack contains four peptides: GHK-Cu (50mg), KPV (10mg), BPC-157 (10mg) and TB-500 (10mg). They are grouped purely as a research convenience, so that a laboratory can obtain and study several peptides that act on different signalling pathways from a single set. The grouping makes no claim about any combined effect; each compound is supplied separately, strictly for in-vitro laboratory research use only.
