Peptide Pens and Supplies
Dispensing pens built for repeatable dosing, with the cartridges and needles that fit them and cases to keep it all together. Everything ships fast from the US.
A complete reusable pen system
Our reusable peptide pen dials 1 to 60 units in single-unit clicks. It takes standard 3 mL glass cartridges and screw-on universal pen needles, so you buy refills when you need them, from us or any other supplier. When a cartridge runs out, you load a fresh one and keep using the same pen.
Everything around the pen is here too: steam-sterilized 3 mL glass cartridges, 31G and 32G universal pen needles, vent needles for filling cartridges, and cases for storing and traveling with your kit. Starting from scratch? The Ultimate Research Kit bundles a pen with five cartridges and a box of needles. To see how it all goes together, watch our how-to videos or read the FAQ.
A peptide tracker app built for protocols
The ShotLog app replaces the notes app and the spreadsheet. Set up a protocol once and it schedules every dose and reminds you when one is due, and it flags any dose you missed. The reconstitution calculator works forward and in reverse, giving you syringe units from your vial and bac water amounts, or the bac water you need for the units you want.
Vial tracking counts down the doses left in each vial, and Biograph charts modeled medication levels from your dose history. Log shots, weight, measurements, progress photos, meals and hydration in one place, then export it all. ShotLog handles peptides and GLP-1s alike, on iPhone and Android or on the web at app.shotlogapp.com. See every feature.
