About RegenaWould 100% recommend. Shipping time, communication and product quality all excellent
Top notch experience!
Great Customer Service Website easy to navigate & very informative Lots of reading material available on all the various peptides Provided a swift & informative response to all my enquiries.
Very great service great quality and trusted I've tested the quality
Trust is everything when buying research peptides, and this company exceeded my expectations. My order arrived quickly, communication was excellent, and I independently tested the peptides myself. The results matched the COA reports exactly, which gave me complete confidence in the quality and transparency of their products. Highly recommended.
Great quality peptides thanks
The best 10/10 go with these guys!!!! Brilliant!!!!

Regena is a small research-peptide supplier run from Fuengirola on the Costa del Sol. We are not a pharmacy, a clinic or a manufacturer: we source lyophilised peptides and laboratory supplies, describe what each kit contains, and ship them to researchers in most countries. Every product on this site is sold as a laboratory reference material for in-vitro research only.
Because we are small, the person who answers your WhatsApp message or email is the same person who checks your order. If something in a product description is unclear, ask before you buy. We would rather answer a question than process a return.
The shop has two kinds of listing. Stocked kits show a price for each available vial size and can be added to the basket straight away. Request-a-quote listings cover peptides we can source but do not hold in stock; those pages open a WhatsApp message with the available sizes so we can confirm price and lead time with you directly.
Products are grouped into research categories such as metabolic, growth-hormone secretagogue, regenerative, cognitive, immune, longevity, cosmetic and hormone-axis peptides, plus lab supplies like bacteriostatic water and acetic acid. The categories describe the area of published literature a compound is studied in. They are not claims about what a product does.
Unless a listing says otherwise, a kit is 10 sealed vials of the same size from the same batch. Peptides are supplied as lyophilised (freeze-dried) powder, the form in which most peptides stay stable during shipping. The milligram figure on a listing is the amount per vial, not per kit.
We do not publish preparation or dosing instructions. Our reconstitution and storage guides cover general laboratory handling only: refrigeration, protecting vials from light, and labelling.
Certificates of analysis we hold are published in the COA library. Most were produced by Janoshik Analytical, an independent laboratory whose reports can be checked against its own online verification system. A typical report gives an HPLC purity result and a mass-spectrometry molecular-weight check for one batch.
Not every product or batch has a published report. Where a report is not listed, batch COAs are available on request. Ask for the report that matches the batch you will receive before you order, and do not rely on a certificate from a different batch.
Choose a size, add it to the basket and enter your delivery details at checkout. Payment is by bank transfer through Wise, Revolut, Monzo, bunq or a standard bank payment. After paying, mark the order as paid and send a screenshot of the transfer so we can match it quickly.
Parcels ship tracked from hubs in Germany, the USA or China, depending on destination and stock. Allow 5–18 business days from the tracking number being issued. Shipping is €60 to Europe and the UK and €70 to the USA, Canada, Cyprus and the Middle East. Optional €40 shipping protection is offered at checkout. We do not ship to Russia or Brazil.
Check that research peptides are legal to import and hold where you are. Rules differ widely between countries, and the buyer is responsible for complying with local law. Read the research disclaimer and shipping policy, and contact us if your country or institution has specific paperwork requirements.
