Compare pre-prepared research peptide pens supplied by Alpha Peptides® in the UK. Each pen contains reconstituted solution rather than lyophilised powder, and every listing states the compound, the listed quantity and the presentation, so you can check the format against your laboratory requirements before ordering. Orders are dispatched from the UK with tracked delivery, and you can check the document library or ask the team for documentation covering a product’s format and batch. All pens are for laboratory and in vitro research only. Not for human or veterinary use.
How research pens differ from vials and atomised solutions
The difference is the supplied format, not the compound name.
- Vials are supplied as lyophilised (freeze-dried) powder, for example DSIP 10mg, TB-500 5mg, Glutathione 1500mg and KLOW 80mg.
- Research pens are pre-prepared dispensing pens containing reconstituted solution.
- Atomised solutions, such as Semax 10mg Atomised Solution, contain reconstituted solution supplied in an atomiser.
A shared compound name does not make different presentations interchangeable, so compare the listing and its documentation for the format you intend to order.

Research pen FAQs
How are research pens delivered?
Standard tracked delivery is available, and free standard tracked delivery applies on eligible UK orders that meet the product-total threshold set out in the Shipping Policy. Most orders are dispatched within 1–2 working days after payment. Available services and final charges are shown at checkout. See the Shipping Policy.
Is documentation available for the pens?
Documentation coverage varies by product and batch. Check the document library or ask us for documentation covering the format and batch you are considering, and check whether a report relates to the source material or the finished pen. For example, the KLOW source-batch report relates to the vial material used to prepare the pens, not the finished pen. See Testing & Documentation.
Does the milligram figure state the volume?
No. On the Glutathione, DSIP and TB-500 pens, the figure describes the listed compound content, not a liquid volume or an amount per dispensing increment. If you need either, contact the Alpha Peptides® team at info@alpha-peptides.co.uk for the current presentation specification.
