Im not trying to be rude but you said your goal is just to put on weight. That does not require complicated protocols. You also said you bulk from 17-20% so frankly it doesn’t matter if your meal prep is locked in because your methodology has a fundamental issue that counteracts the purpose of having a strict meal plan. It’s good you’re cutting down but 12% before a bulk isn’t lean at all, or a good place to start bulking.
You can add whatever you like, bro Im not telling another grown man how to live, Im just saying based on history and the problems you have stated you had, focusing on the process, not the PEDs is likely going to be more beneficial.
Like for example— cutting to an appropriate place to bulk, understanding insulin sensitivity and metabolism, properly adjusting diet In a bulk so you get mostly muscle and not excess fat since you yourself said you bulk too fast which is an error that you want to correct. PEDS won’t correct it whether your run test eq or test deca masteron. There are lots of injectable PED combos that work, and just test alone works too. That choice isn’t where the majority of your progress or lack of it is coming from.
