Community roundup: we summarize and fact-check what the peptide community discusses on Reddit and research forums, then add the exact reconstitution math and handling notes.
“What do I actually need to start?” is the most common beginner question on Reddit. Here is the no-fluff checklist.
The three things you need

A reusable pen, standard 3 mL cartridges, and bacteriostatic water. That is it. Our complete starter kit bundles all three: the Gansulin metal reusable pen, Gansulin 3 mL cartridges, and bacteriostatic water.
Why this combo
It is the durable, precise, low-waste setup the community keeps landing on, and it works with any compound you reconstitute. Nothing proprietary, nothing locked.
First mix
Reconstitute, then use the peptide calculator to get your concentration and unit draw before you dial the pen. The Peptide Reference Library covers compound-specific reconstitution and handling.
