First of creatine and whey protein will do nothing. Whey has strategic uses but that's it and creatine maybe will give some more force or endurance.
The weight you gain depends on your frame, insertions, muscle bellies, muscle contraction coordination and force development. My favorite natural body builder in Jason Gallant, go see this guy on you tube.
And being a incel you probably won't gain that much, unless you stick to it for 10+ years. I would just create a strength base like benching 1.5 BW and shit like that, then make light use of steroids, anywhere near dosages dumb chadlites use to ascend to brad status. Stuff like trenbolone and stanozolol are highly toxic also, masteron, testosterone, anadrol, dianabol, deca... are better.
And never forget to train your neck! Woman see it as a Alpha Male signal!
