Why Regena
The short answer for buyers on the fence.
Every peptide Regena ships is HPLC-verified above 99% by an independent third-party lab, sealed as a 10-vial research kit, and supported by tracked shipping from Germany, the USA or China. We don't sell single vials, we don't hide behind a reseller tier, and we don't upcharge on COA access.
Six reasons researchers pick Regena
HPLC ≥99% purity
Every batch is analysed by an independent HPLC lab before it goes into inventory. Anything below 99% doesn't ship — no exceptions, no re-labelling.
COA on every order
Certificate of Analysis (purity, identity, water content) is attached automatically to each order and stored in your account for internal audits.
24-hour EU dispatch
Orders confirmed before 14:00 CET are dispatched promptly, tracked, insulated for cold-chain compounds, discreet packaging.
Tracked worldwide shipping
Every parcel is tracked from dispatch. Please allow 5–18 business days from when you receive your tracking number.
Talk to a scientist, not sales
The team answering WhatsApp and email is the same team releasing the batch. Zero sales-rep tier between you and the person who signed the COA.
No reseller markup
We manufacture and QC in-house instead of drop-shipping from an unknown warehouse, which is why the per-vial price is often 40–60% below single-vial competitors.
The written guarantee
Every order is tracked, with clear delivery expectations before payment.
- Delivery timing — please allow 5–18 business days after tracking is issued.
- Track your parcel — follow its progress with the tracking number we provide.
- Below-spec batch — if any vial arrives cracked, discoloured or below the COA purity, we replace the affected units 5–18-business-day tracked.
- Customer risk — shipping protection is optional at checkout, and orders placed without it have no shipping protection; the customer accepts transit and customs risk.

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.
