From what I tried myself, moving from the 2.5 level straight to 4 produced a clearer drop in weight than the smaller steps before it. My own sequence went 1 then 2 then 2.5 then 4 then 5 then 6.
On week eight with this compound, first four weeks at the lowest dose then four at double that. Scale had been moving about a kilo each week until now. I had planned to step to the next level for the coming month but the lack of movement has me wondering about going straight to the higher amount instead. I also intended to begin the other peptide at the middle dose during that step-up.
