Frequently Asked Questions
What is Lab Sourced Peptides?
Lab Sourced Peptides is a research-grade peptide supplier built on three principles: verified purity, transparent testing, and fair pricing.
We source, test, and distribute peptides that meet strict analytical standards — so researchers can trust both the data and the cost.
Are your peptides for human use?
How do you test your peptides?
- HPLC (High-Performance Liquid Chromatography) for purity analysis
- LC-MS (Liquid Chromatography-Mass Spectrometry) for molecular identity
- FTIR (Fourier-Transform Infrared Spectroscopy) for structural verification
What does your COA include?
- Purity (%)
- Molecular weight and structure validation
- Retention time and chromatogram
- Batch number and test date
Why are your prices lower than competitors?
Do you compromise quality to offer lower prices?
How should peptides be stored?
- Keep peptides in a cool, dry environment, away from sunlight and humidity.
- For long-term storage, refrigerate (2–8°C) or freeze (–20°C).
- Avoid repeated freeze-thaw cycles to maintain stability. Detailed storage recommendations are included with every order.
