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.

1 kit = 10 vials. Bigger vials = lower price per vial.

What is Phosphate Buffered Saline?

Phosphate buffered saline is a sterile, pH-stable isotonic buffer widely used as a diluent and wash solution in laboratory work. Supplied as a sterile liquid in kits of 10 vials, in 3 ml or 10 ml vial formats. It is not a powder.

Mechanism of action

Isotonic phosphate buffer maintains stable pH and osmolarity for peptide handling and in-vitro work.

Primary research areas

Standard unpreserved diluent and wash buffer for laboratory peptide handling.

Research notes

  • Supplied as a sterile liquid: 10 vials per kit. It is not a powder.
  • Unpreserved — intended for single-session handling rather than extended multi-day vial use.
  • Use bacteriostatic water where a preserved multi-use diluent is required.

What researchers say about Phosphate Buffered Saline

    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.

    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.

    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.

    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.

    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.

    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.
