Founder story
Started from a 300+ lb transformation
Regena Peptides exists because I lived the other side of it. Over 300 pounds, no plan that worked, and surrounded by people selling protocols they'd never tried.
Peptide research changed how I thought about metabolic and recovery science. Once I rebuilt my health, I started getting the same question over and over from friends in Marbella and abroad: "where do you actually source from, and what's worth studying?"
Regena is the answer — a vetted reference, honest sourcing, and direct conversations. No funnels, no pressure, just the resource I wish I'd had on day one.
What people say
Reviews from researchers and clients
★★★★★
"The COA documentation is exactly what I needed for my lab notebook. Purity numbers matched the certificate to two decimals."
★★★★★
"Answered me on WhatsApp within an hour, walked me through reconstitution and storage. Zero pressure to buy anything."
★★★★★
"Packaging arrived discreet and cold. The reference pages on the site are more detailed than most peer-reviewed summaries I've read."
★★★★★
"Finally someone who treats peptides as research compounds and explains them properly. The quiz pointed me to compounds I hadn't considered."
★★★★★
"Honest answers about what's well-studied vs experimental. That alone is worth more than any product page."
★★★★★
"Got a follow-up message a week later just checking how things were going. That's not normal in this space."
FAQ
Frequently asked questions
01What are research peptides?+
Peptides are short chains of amino acids that function as signalling molecules in biological systems and are widely studied in laboratory and academic research for their role in cellular communication systems.
02How do you ensure the quality of your peptides?+
Every batch is subjected to rigorous third-party HPLC testing. Each order includes a Certificate of Analysis detailing purity percentage, molecular weight, and testing methodology. Our reference compounds consistently achieve 99%+ purity.
03How should peptides be stored?+
Lyophilized peptides should be stored in a freezer at -20°C for long-term stability. Once reconstituted, they should be stored in a refrigerator at 2-8°C and used within the timeframe specified in the documentation. Always protect from light and moisture.
04What is the purpose of Bacteriostatic (BAC) water?+
Bacteriostatic water is used in laboratory settings to reconstitute lyophilized peptides under sterile conditions. It is strictly for research purposes and not intended for direct administration.
05What is your shipping process?+
Temperature-controlled shipping preserves peptide integrity. Orders are processed within 24 hours and shipped in discreet, secure packaging with tracking. Express shipping is available for urgent research needs.
06Which payment methods are accepted?+
Secure online payments via PayPal, credit cards, Apple Pay, Google Pay, and offline payment methods. All transactions are processed through approved payment gateways.
07What is your returns policy?+
Due to the sensitive nature of research compounds, we cannot accept returns on opened or used products. Damaged or incorrect items reported within 48 hours of delivery will be replaced or refunded.
