Why we built a pen instead of selling vials
The most common mistake in home peptide dosing has nothing to do with the peptide.
Every pet peptide company sells the same thing: a small glass vial of freeze-dried powder, a vial of bacteriostatic water, and a dosing chart. Reconstitute, draw up, inject. It works, if you do it right.
Here is what "doing it right" involves. Swab both vials. Draw 3 mL of water. Inject it slowly down the side of the peptide vial so you do not foam the powder. Swirl, never shake. Wait. Then convert: your dog's dose is 300 micrograms; the vial holds 10 milligrams in 3 milliliters; that is 3.33 milligrams per milliliter; so 300 micrograms is 0.09 milliliters; on a U-100 insulin syringe that is 9 units. Draw 9 units, tap out the bubble, inject.
We asked owners what went wrong. Too much water. Not enough water. Shaking. Wrong syringe. Reading 0.9 for 0.09. Losing track of which vial was mixed when. A cartridge in a pen removes every one of those steps except the last. The concentration is fixed at fill. The dial reads in the same units as the card. You cannot draw the wrong volume, because there is no drawing.
What it cost us
A pen system is harder to make than a vial. Cartridges have to be filled aseptically by a licensed partner and sterility-tested lot by lot. The pen has to meet the ISO 11608 dimensional standard so any pen needle fits. We fill to 3.15 mL so the two-unit prime never costs you a dose. All of that is why a cartridge costs ten dollars more than a vial kit. We think it is the best ten dollars in the box.
What it gives you back
Ten seconds at breakfast. A number you can trust. A needle your dog barely notices. And a record: with Fieldnotes, every dose can be a dated line in a journal your vet can read.
