Are research peptides legal in Spain?+
Peptides supplied for in-vitro and laboratory research are legal to purchase, possess and ship within Spain and the EU when classified strictly as research compounds — not as therapeutic products. We do not supply for human use, and we do not make therapeutic claims.
How do you verify purity?+
Every batch is tested by an independent third-party laboratory using High-Performance Liquid Chromatography (HPLC). The Certificate of Analysis (COA) is included with every order and lists purity percentage, molecular weight, testing methodology and batch ID.
How should peptides be stored?+
Lyophilised peptides are best kept at -20 °C for long-term stability. Once reconstituted with bacteriostatic water, store between 2–8 °C in a refrigerator and use within the window specified on the COA. Protect from light and avoid repeated freeze-thaw cycles.
What is bacteriostatic water and why does it matter?+
Bacteriostatic water contains 0.9% benzyl alcohol, which prevents bacterial growth in multi-use vials. It's the standard solvent for reconstituting lyophilised research peptides in sterile laboratory settings.
How fast is shipping to Marbella and the Costa del Sol?+
Local Costa del Sol deliveries typically arrive within 24–48 hours. Spain-wide orders ship same-day if placed before 14:00 CET. Temperature-controlled, discreet, tracked packaging on every order.
Do you ship to the UK and the rest of the EU?+
Yes — discreet tracked shipping to the United Kingdom, Ireland, and across the European Union. Express options are available for urgent research needs.
What payment methods do you accept?+
Credit and debit cards, Apple Pay, Google Pay, bank transfer (SEPA), and selected crypto. All transactions are processed through secure, SSL-encrypted gateways.
What if my order arrives damaged?+
Report damaged or incorrect items within 48 hours of delivery with photos and we'll replace or refund — no friction. Because of the sensitive nature of research compounds, we cannot accept returns on opened vials.
Why choose Regena over a Telegram seller or underground forum?+
You get verified compounds (HPLC, COA), a real human on WhatsApp for questions, transparent pricing, cold-chain shipping, and a business with a fixed Marbella address and verified review presence on Trustpilot, Google and Scamadviser. That's not what underground sellers offer.
Do you offer guidance on protocols?+
Yes — book a free 20-minute consultation. We map relevant reference compounds for your goals, walk through mechanism, dosing windows and stacking, and stay available for questions throughout your protocol.
Is my information kept private?+
Absolutely. We never share names, addresses, order history or consultation content with third parties. Discretion is non-negotiable for our clientele.
What's the difference between Retatrutide, Tirzepatide and Semaglutide?+
Semaglutide is a GLP-1 mono-agonist. Tirzepatide adds GIP receptor activity (dual agonist). Retatrutide is a triple agonist that also recruits the glucagon receptor — broadening the pharmacology in research models. See our peptide library for full reference profiles.
