My opinion probably unpopular but I'm gonna take your word for what worked previously and clear desire to use multiple compounds. TypeII talks about HARLEM (sp?) trials and the more compounds used the less negative sides experienced by users aka stacking is healthier than blasting one compound higher.
Too low doses of stuff and too complicated not enough benefit imo.
You had a great experience with test/mast/tren and winstrol/var, noted; will incorporate those. Think you got more gains than 1.5g test? Okay, will take your word for it.
Forget dbol, forget deca you never used, forget proviron plenty of DHT already. I think YK11 is a waste but whatever, go for it dude it won't hurt the gains.
GH absolutely higher than 2iu daily. Pretty much replacement dose. 4iu minimum, imo.
500 - 750 test / 400 mast / 100mg tren / 20mg winstrol / 20mg var / 4 to 6iu GH.
This puts you at 1240 - 1490mg AAS load including tren and orals.
Can you run 20mg of each oral for 24 weeks? Yea. Advisable? Idk you'll have to figure that one out based on your personal response via bloodwork.
This wouldn't be my ideal cycle for gaining mass, but I took the blueprint + your positive past experience with certain compounds left them in and adjusted stuff.
Don't know your stats or goals, hard to give better advice so take this with a grain of salt.
