  • Peptide perfect
Size: 1/2cc-31G 5/16" Number of Items: 20
These are great for the administration of peptides as well as insulin if needed. The lower volume allows for more precise measurement of the medicine especially if you are only using a few units per dose.

Those are my go to ones, always fast shipping, great price, Great quality and packaging. Easy to read due to clear plastic and needle is thin enough to barely notice any pain. They move smooth and have no sharp edges or seams.

  • Painful
Size: 1/2cc-31G 5/16" Number of Items: 20
Every single one I’ve used has been super dull and actually hurts as I’m inserting it. They are such small needles that there shouldn’t be pain. I am so upset with this purchase.
