Certificate of analysis

why 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.

Buy KLOW 80 Pen

The KLOW 80 pen is available directly through Veyvora’s online store. Wholesale accounts qualify at a minimum order quantity of 50 units per SKU. For current pricing in GBP, live stock status and checkout, visit the Veyvora product page directly, as unit price and availability are subject to change.

Batch certificates of analysis (CoAs) are published per lot and accessible before purchase, allowing researchers to review HPLC (High-Performance Liquid Chromatography) purity, mass spectrometry confirmation and endotoxin results before placing an order. Pre-purchase access to this documentation helps procurement teams working under institutional documentation 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), for in-vitro laboratory research, 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. Veyvora’s 2026 product catalogue lists one KLOW 80 SKU; confirm current SKU status directly with Veyvora when placing institutional orders.

Before first use, 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).

The per-click figure of approximately 267 micrograms assumes uniform distribution across all 300 clicks. Researchers requiring precise per-component click values can request the full formulation breakdown from Veyvora directly; the 2026 catalogue publishes the blend at the whole-pen level.

Format and Variant Status

Veyvora lists the KLOW 80 pen as a single SKU in its 2026 catalogue, with one fill volume and one concentration. Confirm excipient composition and solvent details with Veyvora before designing an 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.

Reading the Certificate of Analysis

The HPLC line reports peptide purity for the tested sample from that batch, and the mass spectrometry line confirms peptide identity. The endotoxin line, where published, reports the tested sample’s result against the stated threshold at the time of testing. The certificate applies to the tested lot; an in-house quality check sits alongside it where your protocol requires one.

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. If a batch number does not appear in the public CoA database, contact Veyvora before proceeding. Read component-level purity figures for each of the four peptides, GHK-Cu, BPC-157, TB-500 and KPV, from the batch-specific document.

HPLC Purity: How the Figure Is Measured

For how the HPLC purity figure in the CoA is measured and what it reports, 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; document a strip showing a breach and report it 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 references for every storage parameter; for a value that is not on them, ask 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, confirm the following directly with Veyvora or via the live product page, as these values change:

  • 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

KLOW 80 is supplied for in-vitro laboratory research, such as cell-culture and tissue-repair models and use as an analytical reference material, according to Veyvora’s product information (2026). Not for human or veterinary use. The pen format, click-dose arithmetic and batch documentation support controlled experimental conditions. Confirm that your institution’s procurement framework covers research-grade peptide blends before ordering, as institutional requirements vary.

The pages below address specific technical questions adjacent to the KLOW 80 peptide pen purchase decision.

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 want to evaluate separately before designing assay conditions. BPC-157 and TB-500 compared covers those differences at the compound level.
