You can def get away with that cycle. You should use hcg on cycle (starting week 4) like stated earlier and you should run Nolva /comid together for pct. Plus ai on cycle.
You should bump the dose or toss something else in around week 10-12 because after being on that long the gains start really slow down and the body just maintains. So weeks 12-20 bump to 400 or toss in another compound or oral. If you want to bulk then throw in dbol/ M1T/ superdrol/ abombs. If a cut run var/ tbol/ winni .
I personally would run tbol or var for 6-8 weeks . I think the milder compounds are the best but I react very well to them . But if you choose all out bulk id go with 6 weeks of dbol .
