Frequently asked questions

Are these peptides legal to buy in Australia?

Yes. The research peptides listed here are legal to purchase in Australia for legitimate in-vitro laboratory and research purposes. They are supplied strictly for research use and are not approved for human consumption or therapeutic use.

What does “HPLC purity” actually mean?

High-Performance Liquid Chromatography (HPLC) measures the percentage of the target peptide in a sample versus impurities. Every batch we stock is independently tested, and the exact purity percentage appears on that batch's Certificate of Analysis.

Does every order come with a Certificate of Analysis?

Yes. Each batch ships with a downloadable COA including HPLC purity, mass-spectrometry identity confirmation, sterility results and LAL endotoxin data. You can browse current batch COAs in our COA Library.

How should research peptides be stored?

Lyophilised peptides are best stored at −20°C, protected from light. Once reconstituted with bacteriostatic water, refrigerate at 2–8°C and use within roughly four weeks, avoiding repeated freeze–thaw cycles.

How is this list ranked?

Ranking reflects order volume across our Australian research customers, weighted toward products with in-stock availability and verified current-batch COAs. It is not a statement of efficacy — all products are for laboratory research only.
