Sold as 10-vial kits · minimum order
We don't sell single vials. Every order is a sealed 10-vial research kit — it's how serious labs and long-protocol researchers actually buy, and it's how we keep quality and price honest.
- ✓ Lower €/mg — batching 10 vials cuts our fill cost, and we pass it to you (per-vial price is 40–60% lower than typical single-vial pricing).
- ✓ One batch, one COA — all 10 vials come from the same HPLC-verified lot, so your data stays consistent across a full study.
- ✓ Lasts 8–12 months — a sealed 10-vial kit keeps for roughly 8–12 months in cold storage, so you're not re-ordering mid-study. Once mixed with bacteriostatic water, a vial lasts about 2 months in the fridge (2–8 °C).
- ✓ One shipment, one customs pass — fewer parcels = lower risk, lower shipping cost per vial, faster to your bench.
- ✓ Sealed 10-vial kit (small glass bottles, lyophilised powder)
- ✓ Third-party Certificate of Analysis (COA) for this batch
- ✓ Ships from Germany, the USA or China · tracked & discreet
- ✓ Free re-ship if customs holds your parcel
- ! You'll also need bacteriostatic water to mix your peptides

Customer reviews
What researchers say about Semax
- Verified
COA matched batch number exactly
Ordered three batches of BPC-157 over four months. Each shipment arrived cold-packed with a COA and the batch numbers cross-checked against the public testing database. Purity reported between 98.7% and 99.2% — consistent with what we measured in-house by HPLC.
Dr. M. AnderssonStockholm, Sweden - Verified
Fast UK delivery, clean reconstitution
Discreet packaging, arrived in 5–14 days to London. Lyophilised cake was firm, dissolved completely in bac water with no cloudiness. Dose math in IU on the calculator made repeat dosing trivial.
J. WhitmoreLondon, UK - Verified
Best documentation I've seen from a supplier
We compared three suppliers as part of a sourcing audit. Regena was the only one with chromatograms, retention times and lab-named COAs published per batch. That's the standard the rest of the industry should meet.
Prof. L. RomanoMilan, Italy - Verified
Good product, customs took an extra day
Product itself is excellent — clean reconstitution, COA available. Customs added 24 hours which is outside Regena's control. Support replied within an hour when I asked for an update.
K. PetersenCopenhagen, Denmark - Verified
Independent lab agreed with stated purity
We sent a sub-sample to an independent lab. Their result was within 0.4% of the published Regena COA. That's a level of transparency you almost never see in research-peptide sourcing.
Dr. S. PatelBirmingham, UK - Verified
Cold chain held the whole way
Temperature indicator strip in the package stayed in the green. Vials still chilled on arrival despite a 3-day route. Whoever packs these boxes knows what they're doing.
