The Science
What Are Research Peptides?
Peptides are short chains of amino acids — typically 2 to 50 — linked by peptide bonds. They serve as signaling molecules in biological systems, making them essential tools for studying receptor binding, metabolic pathways, and cellular processes in controlled laboratory environments.
At LifeSpanSupply, every compound is synthesized using solid-phase peptide synthesis (SPPS) and purified via reverse-phase HPLC. The result: pharmaceutical-grade lyophilized powder with verified purity of 99% or higher — ready for your research protocols.

Common questions
What buyers ask before ordering.
What purity do LifeSpanSupply peptides ship at?
Every batch is independently verified at ≥99% HPLC purity by third-party laboratories — never in-house. Each shipment includes a batch-specific Certificate of Analysis with the chromatogram, mass-spectrometry identity check, and lot traceability.
How are peptides shipped and stored?
Lyophilized peptides ship in temperature-controlled mailers with desiccant. Once reconstituted, store at 2–8 °C and use within the window indicated on the COA. Lyophilized vials remain stable at room temperature for up to 24 months when sealed.
Where do you ship internationally?
We ship across the EU and EEA in EUR, the United States, Canada, UK, Australia, Singapore, Hong Kong, New Zealand, UAE, Israel and Mexico in USD, and Thailand in THB. Free shipping over €100 / $100, ฿2,000 — €9 / $9 below.
Do you carry GLP-1 peptides like Semaglutide and Retatrutide?
Yes — our weight-management catalog includes Semaglutide, Tirzepatide, Retatrutide, and Liraglutide across multiple brand tiers. All are research-grade reagents with the same ≥99% purity standard.
Is there a loyalty program?
Yes — the LifeSpan Circle. Members earn 1 point per $1 (or €1, or ฿30) and unlock 5–20% off every order across three tiers (Bronze, Silver, Gold). Free to join, automatic at checkout — see /lifespancircle for full details.
