The Research Fields
Five research ranges, grouped by the pathway each compound acts on: metabolic, the GH axis, tissue repair, neuropeptides, and melanocortins.
Verification standard
The Synthesis-to-Shipment Journey.
Peptide stability and purity are highly sensitive. We protect the integrity of your laboratory research through rigorous, continuous controls at every phase.
Synthesis & Batching
01Precision synthesis under certified laboratory conditions, ensuring exact peptide chain sequencing.
HPLC Purity & Identity
02Every batch is analysed by HPLC for purity and identity against a reference standard. We only accept 99%+ purity.
Cryogenic Storage
03Lyophilised vials are instantly stored at -20°C in our facility to preserve structural integrity.
Discreet Same-Day Dispatch
04Each order is sealed in discreet, protective packaging and dispatched same-day before 2pm, with tracked UK delivery.
Reconstitution
Plan your reconstitution before you open the vial.
Working out the concentration and dilution volume for lyophilised peptides is central to reproducible research. Use our interactive mini calculator to plan your stock concentration in mg/ml before you reconstitute.
Kovalabs supplies reference chemicals for laboratory assessment only. Work out the dilution here first, so the concentration in the vial is a number you set rather than one you discover later.
