Certificate of analysiswhy a pen beats
a vial & syringe
Traditional research peptides arrive as lyophilised powder that must be reconstituted, drawn into insulin syringes, and converted from milligrams to units by hand, every step a chance for a dosing error.
A multi-dose pen removes the whole failure chain. The peptide arrives already dissolved and calibrated. Attach a fresh needle, turn the dial until you count your clicks, and you're done, the same audible-click mechanism trusted in insulin and GLP-1 pens worldwide.
Pens travel and store better, too: no open vials, no bent needles, no septum contamination after repeated draws. One sealed barrel, ten sterile needles, one dosing card.
how to buy
peptides safely
The peptide market has a purity problem: independent surveys routinely find underdosed, mislabelled or contaminated product sold online. The only reliable defence is third-party verification you can check yourself, not a supplier's own claims.
Before buying any peptide pen, ask three questions. Is every batch tested by an independent lab? Is the certificate of analysis available, so you can check your exact lot before first use? And does it ship cold-chain, insulated and gel-packed, so what was tested is what arrives?
Veyvora answers yes on every order, independent assay, a CoA on request against the batch number, and cold dispatch within 24 hours, paperwork packed inside.

Pre-purchase access to this documentation helps procurement teams working under institutional compliance requirements.
Product Identity and Scope
Veyvora supplies the KLOW 80 peptide pen as an 80 mg multi-peptide research compound in a 3 mL, 300-click pen format, blending GHK-Cu (50 mg), BPC-157 (10 mg), TB-500 (10 mg) and KPV (10 mg), intended exclusively for in-vitro laboratory research and not for human administration, according to Veyvora’s product specification (2026).
Veyvora lists the KLOW 80 pen as a single SKU with a fixed 80 mg total peptide load per unit. The pen format delivers repeatable dispensing across 300 clicks, with each click releasing approximately 267 micrograms of the combined blend, calculated by dividing the total 80,000 µg load by 300 clicks. Any variation in fill volume between pens would shift this per-click value proportionally. No reformulated or alternative-volume variants appear in Veyvora’s 2026 product catalogue; researchers should confirm current SKU status directly with Veyvora before placing institutional orders.
Before first use, procurement teams should match the batch number printed on the pen against its published CoA. The workflow for doing so is covered in detail at how to verify your batch against a CoA.
Verified Specifications
The KLOW 80 peptide pen carries a fixed 80 mg total peptide load across four components, GHK-Cu (50 mg), BPC-157 (10 mg), TB-500 (10 mg) and KPV (10 mg), housed in a 3 mL multi-dose pen delivering 300 discrete clicks, according to Veyvora’s product specification (2026).
Composition and Click Arithmetic
| Parameter | Value | Source |
|---|---|---|
| Total peptide content | 80 mg | Veyvora product spec, 2026 |
| GHK-Cu | 50 mg | Veyvora product spec, 2026 |
| BPC-157 | 10 mg | Veyvora product spec, 2026 |
| TB-500 | 10 mg | Veyvora product spec, 2026 |
| KPV | 10 mg | Veyvora product spec, 2026 |
| Fill volume | 3 mL | Veyvora product spec, 2026 |
| Total clicks per pen | 300 | Veyvora product spec, 2026 |
| Peptide per click | ~267 micrograms | Calculated: 80,000 µg ÷ 300 |
The per-click figure of approximately 267 micrograms assumes uniform distribution across all 300 clicks. Researchers requiring precise per-component click values should request the full formulation breakdown from Veyvora directly, as component-level click arithmetic is not published separately in the 2026 catalogue.
Format and Variant Status
Veyvora lists the KLOW 80 pen as a single SKU with no alternative fill volumes or concentration variants in its 2026 catalogue. Excipient composition and solvent details are not confirmed in publicly available product data; confirm these with Veyvora before designing any in-vitro protocol. For component-level context on two of the four peptides, see BPC-157 and TB-500 compared.
Batch Documentation and Analytical Evidence
Veyvora states that each KLOW 80 batch undergoes testing by two independent laboratories using HPLC, mass spectrometry and endotoxin assay, with a CoA published for batch verification, according to Veyvora’s product information (2026). The CoA is batch-specific: it covers the lot number printed on the pen’s label, not the formulation in general.
What a CoA Can and Cannot Confirm
A CoA produced via HPLC and mass spectrometry confirms peptide identity and purity for the tested sample from that batch. It cannot confirm that every individual pen within the batch is identical to the tested sample, nor does it substitute for an in-house quality check where your protocol requires one. Endotoxin assay results, where published, confirm the tested sample fell below the stated threshold at the time of testing; they do not confirm stability after dispatch.
Before first use, match the batch number on your pen to the corresponding CoA on Veyvora’s portal using the step-by-step process set out in how to verify your batch against a CoA. A batch number absent from the public CoA database warrants direct contact with Veyvora before proceeding. Component-level purity figures for each of the four peptides, GHK-Cu, BPC-157, TB-500 and KPV, should be confirmed from the batch-specific document rather than inferred from catalogue-level claims.
HPLC Purity: Scope and Limits
For a clear account of what the HPLC purity figure in the CoA actually demonstrates and where its evidential limits lie, see what HPLC purity does and does not prove.
Handling and Storage
Veyvora dispatches KLOW 80 orders within 24 hours in insulated, gel-packed 2–8 °C mailers fitted with a temperature-indicator strip, according to Veyvora’s product information (2026). Upon receipt, inspect the temperature-indicator strip before opening the outer packaging; a strip showing a breach should be documented and reported to Veyvora before the pen is used.
Storage Conditions
Once received, store the KLOW 80 pen at 2–8 °C and keep it away from direct light. Do not freeze unless the batch-specific CoA or label explicitly permits freezing, because freeze-thaw cycling degrades peptide integrity in multi-component blends by disrupting the structural conformation of each peptide in sequence. Veyvora’s label instructions and the batch CoA are the authoritative references for any storage parameter not confirmed here; values absent from those documents should be verified directly with Veyvora before proceeding.
For broader context on how temperature and humidity affect peptide stability beyond the dispatch window, see research-peptide storage and stability guidance.
Ordering Information
Pricing, stock availability and exact delivery terms for the KLOW 80 peptide pen are subject to change; confirm current figures directly on Veyvora’s research-peptide catalogue before placing an order. All transactions are conducted in GBP (£), and Veyvora’s product information (2026) states that orders are dispatched within 24 hours of confirmation.
What to Confirm Before Ordering
Before completing a purchase, verify the following directly with Veyvora or via the live product page, as these values are not reproduced here to avoid publishing stale data:
- Current unit price in GBP (£) and VAT treatment for UK research institutions
- Available batch numbers and corresponding CoA download links
- Minimum order quantities for distributor accounts, noting that wholesale accounts qualify at 50 units per SKU
- Accepted payment methods and the returns or replacement policy in the event of a confirmed cold-chain breach on arrival
Delivery lead times beyond the 24-hour dispatch window depend on the carrier and destination postcode; confirm estimated transit times at checkout.
Research-Use-Only Limitations
KLOW 80 is supplied strictly for in-vitro laboratory research and is not presented as a product for human use, according to Veyvora’s product information (2026). The pen format, click-dose arithmetic and batch documentation support controlled experimental conditions, not personal administration, treatment protocols or clinical outcomes. Researchers should confirm that their institution’s procurement and ethics frameworks permit the acquisition of research-grade peptide blends before ordering, as institutional requirements vary and non-compliance can affect both the validity of the research and the legality of the purchase.
Related Research and Comparison Pages
The pages below address specific technical questions adjacent to the KLOW 80 peptide pen purchase decision without importing claims that belong to a separate evidential context.
Researchers who want to understand the stability conditions underpinning KLOW 80’s 2–8 °C dispatch protocol in greater depth will find that research-peptide storage and stability guidance sets out the mechanisms by which temperature excursions affect peptide integrity and identifies which monitoring records to retain.
Two of KLOW 80’s four components, BPC-157 (10 mg per pen) and TB-500 (10 mg per pen), according to Veyvora’s product specification (2026), carry distinct in-vitro profiles that researchers may need to evaluate separately before designing assay conditions. BPC-157 and TB-500 compared covers those differences without conflating them with the blended KLOW 80 formulation.
