Let the vial reach room temperature, add bacteriostatic water slowly down the inside wall rather than directly onto the powder, and swirl — never shake. Use our calculator to fix the concentration before you draw.

Sealed lyophilized vials sit comfortably at 2–8 °C and keep for well over a year at -20 °C. Reconstituted material belongs in the fridge, shielded from light, and is typically worked with inside three to four weeks.

Fix your vehicle control, keep freeze-thaw cycles to a minimum by aliquoting after reconstitution, and log the batch number with each run so results stay traceable to a specific certificate.

Metabolic research compounds, growth-hormone-axis secretagogues, tissue-repair peptides, cellular longevity compounds and neuropeptides each behave differently in storage and solution. Category pages group them accordingly.

Domestic orders avoid customs entirely — everything we ship leaves from Ontario. Inspect the cold pack on arrival and refrigerate the same day for best results.
Our reconstitution calculator works out concentration and draw volume for any vial.
