For size there arent many options - test, eq, deca, tren.
Pick one, two or three of these and go.
Test id say - 1g as base. Then if u take EQ, 700-1000, depending on how your e2 reacts on it.
1g of test, 1g of deca. 1g of test, 700 tren E. 1g of test, 500eq, 500 tren. U get the idea.
As far as picking EQ because its “milder” - it is also milder gains, so longer time on it, so at the end its the same.
What i dont suggest is doing these stupid doses of like 500mgs of anything.
If you have the genetics to aim to do a show, you will gain like 80% of your lifetime size in 1-2 years in the offseason.
Look at the top bodybuilders now, and look at em 2 years back. Most of their size was there already. Look at Cbum - he has improved, but its not like he has doubled the size. Most of his size was there 3 years ago.
Most bodybuilders dont get noticably bigger year after year. They start with most of the size and then they work for details, so going into a show on 500mgs of anything just means it will take 10 years until you reach the size thats any good.
Pro bodybuilders make very small improvements year after year. The size is there when they start, so the approach of spending 10 years on what needs to be done in 2, is setting yourself up for a fail.
If you cant gain serious size on a 2 year blast, you have nothing to do in bodybuilding, besides just “enjoying the journey for yourself” and maybe competing in a show in someones backyard, and being the champion of people who suck at this.
20yrs is not young. McCarver turned pro at 21. Sure he is not the best example but if he would have lived, he would have been very good.
Basically, by the time you are 22-23, you should have ALL THE SIZE you can hold, and then work on it so by the age of 27 you look like something.
If one of these stages dont go well, you should just drop the idea.
As far as people crying about high dosages…well, if something doesnt work out, you can ALWAYS lower the dose.
What you cant, is turn back time, and up it 10 years back, haha.
Go 200% for one year. If you dont have what it takes at least you can move on knowing you did it all.
