Keep a peptide nasal spray in the fridge at 2 to 8 °C once it is opened, standing upright with the cap on and away from light, and follow the storage directions on its label. Vistara Labs sprays arrive ready-mixed in sterile saline in a sealed metered pump, so there is nothing to reconstitute. What…

Most peptides last 8 to 12 weeks after mixing with bacteriostatic water, kept in the fridge at 2 to 8 °C, with quality slowly starting to fade from around week 6 to 8. That is Vistara Labs’ handling guidance, with one clear exception: tesamorelin lasts about a week at most once mixed. Reta (GLP-3) follows…

GHK-Cu is a copper-binding tripeptide studied in skin, tissue and copper-enzyme research. What the copper complex is and how to check what you are buying. Research use only.

Tesamorelin is a modified version of a hormone your body already makes. The natural molecule, growth hormone releasing hormone, is broken down in circulation within minutes. Tesamorelin is that same sequence with one structural change designed to slow the breakdown down — and that change is essentially the whole point of the compound. Findings Tesamorelin…

NAD+ is not a peptide. It sits in peptide catalogues, gets ordered alongside peptides, and is discussed in the same research conversations — but structurally it belongs to a different class of molecule entirely. That distinction is useful context for anyone researching it, because it changes what the purity figure on the certificate of analysis…

Bacteriostatic water is sterile water with one addition: roughly 0.9% benzyl alcohol. That single ingredient is the entire difference between it and ordinary sterile water, and it is the reason it is the standard diluent in peptide laboratories rather than a nice-to-have. Findings Bacteriostatic water is sterile water plus about 0.9% benzyl alcohol, which stops…

CJC-1295 and Ipamorelin act on growth hormone signalling by different routes. What the no-DAC form is, why the distinction matters, and how to verify it. Research use only.

MOTS-c is a mitochondrial-derived peptide studied for cellular energy and metabolic signalling. What it is, how it is supplied, and how to verify purity. Research use only.

A 10 mg vial of MOTS-c reconstituted with 2 mL of bacteriostatic water gives a concentration of 5 mg/mL; with 1 mL it gives 10 mg/mL. The 40 mg vial gives 20 mg/mL with 2 mL of water, 10 mg/mL with 4 mL and 5 mg/mL with 8 mL. The calculation depends only on the…

A 50 mg vial of GHK-Cu reconstituted with 2 mL of bacteriostatic water gives a concentration of 25 mg/mL; the 100 mg vial gives 50 mg/mL with 2 mL and 20 mg/mL with 5 mL. GHK-Cu vials carry far more peptide than most of the catalogue, so the concentrations run higher and the syringe volumes…

A 10 mg vial of tesamorelin reconstituted with 2 mL of bacteriostatic water gives a concentration of 5 mg/mL; with 1 mL it gives 10 mg/mL. The calculation depends only on the quantity of peptide in the vial and the volume of water added, so the figures below apply to any 10 mg vial. There…

Vistara Labs ships peptides to addresses across Ontario, from Toronto and the rest of the GTA to Ottawa, Hamilton, London, Kitchener-Waterloo, Windsor, and north to Sudbury and Thunder Bay. Every order travels inside Canada by tracked Canada Post Xpresspost, so there is no border crossing and no customs step, and prices are in Canadian dollars….
