And she encourages dividing up even the 1mg-6 unit injection into 2 injections of 3 units each - apparently injections with GHK-cu at three or under greatly reduce/eliminate ISRs, and injecting them next to each other, and THEN, and only with these peptides, using a hand massager on the area for 2-5 minutes after injecting. I actually bought a cheap hand massager, and because this is a daily series of injections for the 6 weeks on, I bought a reusable cartridge pen that comes with pen needles and extra cartridges, to use with this protocol, because I'd really like to not have to draw up every day and then inject myself at least 2x each time. At 1.5mg (9 unit) dose that would be 3 injections each time, and I guess 4 with the 1.75mg/10.5 unit injection.
