Customer reviews
What researchers say about MK-677
- 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 48 hours 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.
