I think we both agree on the idea of not increasing dosages until someone stalls and they don't have any side effects. However, the earlier tirtration schedule wasn't necessarily accurate. The titration schedule only says 5mg, 10mg, or 15mg is maintenance. Also the price direct from manufacture is the same whether you get 2.5mg or 15mg, so it's actually technically cheaper with increased dosages.
Again, absolutely correct that there is no need to increase if it's effective, especially if going gray, because we are talking about individuals here, but the data does show that there is a dose-dependent increase with average weight loss on tirz with mean body weight change of 15% on 5mg, 19.5% on 10mg, and 20.9% on 15mg. SURMOUNT-1 also showed 30% of people losing over 20% of their initial weight on 5mg and 57% of people losing over 20% of their initial weight on 15mg. Data also showed that although there is a plateu with tirz, 10mg and 15mg showed a longer amount of time to reach the plateau when compared to 5mg.
In my opinion, if you are not under the medical supervision of a provider then it is a good idea to follow current evidence based practice when doing your own research with these research peptides, and the data is all out there and free!
