Well, you won't *need* Tren of any ester in order to grow, but nothing else will compare to the extreme results of tren. And man, I would only use tren very very sparingly. It tends to be nasty as fuk on just about every health level (lipids, organs...everything). In the right circumstances, and given the right "prep" or lead up, you could grow on just Test + NPP and maybe a little Mast. It won't be 40lbs of bodyweight, but it'll be growth. Don't let tren set your standards or expectations.
Also, plateaus can be as much about training/food as drugs, or even moreso. You're only going to do so much growing before mechanisms, or something else, kicks in to stall it. Getting bigger isn't linear. You have to have periods where you back off; surely your familiar with the concept of periodisation? You should be periodising your training, your food, and the drugs.
If you've legit been off 3 months, that's great. I'd 100% advise getting bloodwork though to double check your lipid and CBC values are back in range. Do not blast if they're not.
If you've been eating around maintanence for those 3 months, that's good too. You're kinda primed to grow when you up the calories more. What's your bodyfat at? You'll always have much more successful bulks the leaner you are. So maybe you might want to look at putting on more muscle as a much more long term endeavor....and do a cut first. Your call, of course.
You finished your last blast, dropped all PEDs except hgh? That doesn't sound right to me. Did you PCT? Or still on a low dose of Test?
