40 days
Anadrol 100mg / Nolvadex 40 mg a day
Test Suspension 150mg a day
Tren A 50mg a day
Test E 500 mg a week
Then continue with the 500mg test e for some time.
This is ridiculous and I seriously hope this is a joke - why the hell would he jump from 900mg a week straight to 2600mg ?! I doubt that he would see that much more
gains than when he would just up the dose a bit, maybe by 300-400mgs ... and my personal opinion on the suggested stack is that it's got too much test and I also don't see a point of using test suspension here but that's my personal preference.
The question is dumb anyway because no one can tell you how much you will need to gain xy lbs of muscle but what I can tell you is that for someone like you who has been working out for some time now it will take quite some time to put on 20lbs of muscle and you should not try to rush it by just doubling your dose.
I would just increase the dose slowly and take some time "off" every now and then like 250mg of test / week for 2 months at least twice a year.
Deca works well for me but you might want to try out different steroids and see what you like best because from personal experience I would say that it's pretty individual what gear works the best for you.... tren is great though and I can't think of anyone who did not like the gains from it but some experience pretty harsh side-effects.
