Research peptides at Pepsup

Pepsup supplies high-purity research peptides to laboratories and researchers across Europe. Every vial is supplied at 99%+ purity as lyophilised powder, and shipped tracked and discreet from within the EU. Browse by category for weight and metabolic peptides like Semaglutide, Tirzepatide and Retatrutide, recovery and repair peptides like BPC-157 and TB-500, growth and performance peptides, and more. Pricing is per vial with bulk and complete-kit options. All products are sold strictly for in-vitro laboratory research use only and are not for human or veterinary consumption.

What arrives, and how it is packed

Each reference is sold as a single sealed vial of lyophilised powder. The product page lists the available sizes, the form, the stated purity, the storage conditions and the intended use, so the specification is readable before anything goes in the basket. Orders are packed and dispatched from the Netherlands with PostNL, booked through MyParcel. Every parcel is tracked and travels in plain, unbranded packaging that gives no indication of the contents.

Batch documentation

A Certificate of Analysis records the identity and purity of one production batch and is tied to the batch number printed on the label. The lab report library is being built as the batch-testing programme comes online, so a product without a published report simply has none yet. Write to us with a batch number and you will get a straight answer about what documentation exists for it.

Reconstitution and supplies

Lyophilised material has to be brought into solution before it can be measured. The reconstitution guide covers the laboratory side of that, including a mixing calculator that converts units and concentrations. Bacteriostatic water, sterile syringes and alcohol prep pads are listed under supplies and ship in the same parcel, or come bundled in a complete kit.

Ordering, returns and questions

Checkout runs through Stripe, with card and local methods such as iDEAL, and cryptocurrency is also accepted. Unopened vials can be returned within 14 days of delivery; once a seal has been broken a return is not possible, which is the normal rule for sealed goods. Details of delivery times per country and the full return conditions are on the shipping and returns page, and the FAQ answers the questions that come up most often. Everything on this page is supplied for in-vitro laboratory research only, and is not for human or veterinary use.
