Peptide Liquid Sprays for Research
Peptide liquid sprays are research compounds supplied pre-dissolved in solution at a stated concentration, in a metered pump bottle. The format removes the reconstitution step entirely. Frontier Peptide Labs supplies seven liquid-format compounds, each manufactured in the USA, third-party tested and shipped with a Certificate of Analysis available per lot.

What is in this category
Neuroactive research peptides in this range include Semax (50 mg) and Selank TP-7. Repair and signalling compounds include BPC-157 (30 mg) and the BPC-157 / TB-500 blend (60 mg / 30 ml). Also stocked are PT-141 (30 mg / 30 ml), IGF-1 LR3 (2 mg) and NAD+ (1500 mg / 30 ml).
Working with pre-dissolved solutions
The defining variable for a liquid-format product is concentration rather than reconstituted mass. Divide the stated compound mass by the stated volume to obtain mg/ml — a 30 mg / 30 ml product is 1 mg/ml. Because the material arrives already in solution, no solvent selection, no reconstitution arithmetic and no pipetting into a lyophilised cake are required, which removes several common sources of preparation variance.
The trade-off is stability. A peptide in aqueous solution is subject to ongoing hydrolysis, oxidation and, for some sequences, deamidation — degradation pathways that are largely arrested in the dry state. Lyophilised material stored at −20 °C has a usable life measured in years; the same peptide in solution is measured in weeks to months. Plan experimental timelines around the solution format rather than assuming vial-equivalent stability.
Handling and storage
Refrigerate at 2–8 °C, keep the bottle sealed between uses and protect from light. Avoid repeated warming to ambient temperature, which accelerates degradation. NAD+ in particular is sensitive to oxidation and light exposure — our guide to NAD+ laboratory handling covers this in detail.

Purity and COA verification
Every lot is analysed by an independent third-party laboratory, with identity confirmed by mass spectrometry and purity by HPLC. Certificates are published on our COA and lab reports page, and our guide to reading a Certificate of Analysis explains how to interpret them.
Frequently asked questions
What is a peptide liquid spray?
A peptide liquid spray is a research compound supplied pre-dissolved in solution in a metered pump bottle, rather than as lyophilised powder requiring reconstitution.
How do liquid sprays differ from vials?
Vials contain lyophilised powder that must be reconstituted before use and allow the researcher to set the concentration. Liquid sprays arrive at a fixed concentration, require no preparation, but have a shorter usable window because the compound is already in solution.
How do I calculate the concentration?
Divide the compound mass stated on the Certificate of Analysis by the stated solution volume. A 60 mg / 30 ml product is 2 mg/ml.
How should liquid sprays be stored?
Sealed, refrigerated at 2–8 °C and protected from light. Solution-format products degrade faster than lyophilised powder, so they have shorter working stability than their vial equivalents.
Are these products tested for purity?
Yes. Every batch undergoes independent third-party HPLC and mass spectrometry analysis, and the resulting Certificate of Analysis is published per lot.
Are peptide liquid sprays suitable for human use?
No. All products in this category are supplied strictly for laboratory research and are not approved drugs, supplements or products for human or veterinary use.
