Belly is good since I stopped injecting tirz there, for some reason tirz is better for me on the arms. You do three separate injections one for each peptide, I think I recall, I'll be mixing mine together, but she said if you can keep each injection under 5 units, shouldn't have any ISR - although perhaps that applies only to if blended - and that using the same syringe is fine for 2 or 3 injections. And the injections should be all together in a line or cluster not separated. And I asked about hand massage and she said hand massage is useless, the massage gun is needed for this protocol only. She said re time, 6 weeks minimum, then a month off, then 6 weeks on, month off.
