More Havoc vs Stacking

My last cycle was a 3wk @ 40mg cycle and I was thinking about going up to 50mg for 3wks. However I was told that I should just keep it at 40mg & stack it with something.

What would be better in terms of:

strength increases?
size increases?

My main concern is sides. My first cycle showed good promise with both strength increases and the ability to maintain gains and very little sides; only minor facial acne during PCT.

( Naturally, either way I will be keeping some nolvadex on hand as well as keeping my liver in good heal appropriately. )

I think you should consider yourself lucky that you had a good run with a DS and not push the envelope. Why not get some real AAS take less of a risk?

No source. Also, I have an extra bottle of it…
