Guides

Plain-language guides to preparing, injecting and storing peptides, and to reading the evidence behind them.

• How to reconstitute a peptide vial, step by stepMixing a freeze-dried peptide with bacteriostatic water: what you need, the steps, how to work out the ml per dose and how long the vial keeps.
• Where to inject peptides and how to rotate sitesThe five subcutaneous injection areas, the technique, and a rotation that keeps the skin healthy and absorption even.
• Semaglutide vs tirzepatide vs retatrutideHow the three weekly weight-loss injections differ: how they work, what the trials showed, side effects and approval status.
• How to read a 1 ml syringeThe ml scale of a 1 ml syringe explained: what each line means, where to read the dose, and how to draw small volumes accurately.
• How to store peptides before and after mixingKeeping peptide powder and mixed vials in good condition: temperatures, light, how long they keep, travelling and when to throw a vial away.
• What the evidence levels meanApproved, approved in some countries, human studies, lab and animal studies: how uPrime labels the evidence behind each peptide, and research versus community protocols.
