How to buy peptides online: a step-by-step guide
How to buy peptides online without guesswork: find the right compound, check the details, add what you need to mix and store it, and check out with the best price. Here is the process at Peptira.

How to buy peptides online, in five steps
Knowing how to buy peptides online mostly comes down to checking a few details before you pay. These are the steps we recommend at Peptira, and they work at any store.
1. Find the exact compound
Search by name in the header, or browse a research area such as GLP-1 peptides or healing and recovery peptides. Some compounds have code names: at Peptira, SEMA-1 is semaglutide, TIRZ-2 is tirzepatide, RETA-3 is retatrutide and CAG-4 is cagrilintide.
2. Check the details on the product page
Before adding anything to the cart, confirm the compound name, the amount per vial, the format and the SKU. On BPC-157 10mg, for example, the specifications list the sequence, the molar mass and the 10mg amount, and the label on the vial matches.

3. Pick the right size
Work out how much your study needs in total, then compare sizes. Bigger vials usually cost less per milligram: RETA-3 30mg is about $5.97 per mg against $9.90 for 10mg. Smaller vials suit short pilot runs.
4. Add what you need to mix and store it
Freeze-dried peptides need a liquid. Add bacteriostatic water 10mL or 3mL, plus acetic acid if a peptide won’t dissolve in water. A 10 vial kit case keeps vials upright in the fridge. Shipping is free either way, so it costs nothing extra to add them.
5. Check out with the best price

After you buy peptides online: storage
Once you know how to buy peptides online, storage is the next step. Put freeze-dried vials in the freezer at -20°C. When you mix one, add the water slowly down the side of the vial, swirl gently and keep it in the fridge at 2 to 8°C. Use it within about four weeks.
