I have a chance to purchase 30g needles. I've been using 29 g for my mod-grf and ipa usage. Are 30g needles large enough for the peptides to get through. Thanks in advance!
30 is fine of course, but I think you may be happier with 29's. If you're glute shooting you may find having to remain twisted around long enough to push through that smaller gauge to be a bit tiresome now that you've acclimated to your 29's.
