It's okay to go slow; I started my wife at 0.5mg as she was concerned about potential side effects. If you've been on 1.5mg for at least a couple weeks, bump it to 2mg for two weeks and do the 0.5mg bump every two weeks until you feel like the hunger signaling isn't bothering you -- for example I pin Sunday evening and if I start to get hungry on Thursday, I know it's time to increase again. If I start to get hungry on Saturday, I stay at the same dose.
Due to serum concentration levels and signaling peaks, I don't personally think it is necessary to split your dose; dose splitting came into play more as a means to mitigate some of the side effects rather than maximizing effectiveness of the peptide. I would rather see someone doing 3mg in a single pin weekly than two 1.5mg every 3.5 days (assuming no side effects) just due to the 3mg sending a stronger signal. Splitting won't kill you, and there's nothing inherently wrong with it, I just wanted to provide a little background.
It's alright that you're being patient. The patient people tend to have long-term success. Consider the gradual bumping up; there's no race to find maximum dosing without side effects if you get benefits from a lower dose.
