GLP-1 Apprentice

FWIW I use a pen for GHKcu as I pin it 7 days a week. Turns out I'm someone who gets welts (not pain) from it so I'm still working on how much BAC water I need and will be switching back to syringes as a result of that so I can pull more BAC if needed. (I currently recon 50mg with 5ml BAC and pin 2mg daily)JulezZ said:I think about starting GHKcu, but as you have to pin every day, I'd like to get a pen. Are there refillable ones, and are there sterile cartridges you can fill with reconstituted solution? I'd be happy to hear you recommendations / experience!
