I honestly hate pinning, too, but volume kills me in each syringe, so I hate pinning too much at each site and it heels faster and absorbs with less volume. At least it feels like it does and I can hit that spot again later at end of week, if needed.
I think with the 3iu’s of GH and 300/300, your going to shine, cause you’re already looking amazing titrating up like you’ve been doing since adding in the Mast and GH.
