Pyrox Labs FAQ

Pyrox Labs stocks a comprehensive range of research peptides and biochemical compounds including metabolic research compounds (SM1, TZ2, RT3), peptide compounds (NAD+, GHK-Cu, MOTS-C, IGF-1 LR3, Selank, Semax, SS-31, Tesamorelin, Cagrilintide), combination blends (BPC-157 + TB-500, CJC-1295 + Ipamorelin, Glow 70mg), research bundles and lab essentials. See our full shop for current availability.

Possibly — email [email protected] with the compound name and required quantity. We regularly expand our range based on researcher demand and will let you know availability and timelines. We cannot guarantee sourcing for all compounds.

All Pyrox Labs compounds are supplied in lyophilised (freeze-dried) powder form in sealed research vials. Lyophilised compounds are more stable during storage and transport than liquid solutions. They must be reconstituted with bacteriostatic water before use. See our Reconstitution Guide for instructions.

All Pyrox Labs compounds are independently tested by Janoshik Analytical and must meet a minimum purity of ≥98% by HPLC before being listed for sale. Full COA documentation including purity data is available on our COA Hub page or on request by emailing [email protected].

SM1 is a GLP-1 receptor mono-agonist. TZ2 is a dual GLP-1/GIP receptor agonist — adding GIP receptor pathway activation. RT3 is a triple GLP-1/GIP/Glucagon receptor agonist — the most complex of the three. See our GLP-1 Research Guide for a full comparison.

Yes — we offer multi-vial research bundles for RT3 (30mg, 60mg, 80mg) and TZ2 (30mg, 40mg). Bundles offer better value per milligram for extended research protocols. All bundle vials come from the same batch as individual vials.

See our comprehensive Reconstitution Guide which covers equipment needed, step-by-step instructions, dilution calculations and storage guidance. The key points are: use bacteriostatic water, add water slowly down the vial wall, swirl gently — never shake, and store reconstituted compounds refrigerated at 2–8°C.

Lyophilised (powder) compounds should be stored at room temperature away from direct light and moisture. Once reconstituted, store refrigerated at 2–8°C and use within 28 days. Never freeze a reconstituted solution. See our Reconstitution Guide for full storage information.
