400MG of Sustanon would have been PLENTY. Drop the Deca and repeat the cycle using Sust only.
Dont fuck with Primo or Deca, its not going to add a lot and you are just going to damage your body even more for no good reason.
If your hell bent and "making more gainz" this time around, extend the cycle by 1 month, it will be safer than taking all this extra bullshit that only a Pro whos carreer depends on muscle size and has accepted the consequences should be messing with.
Any gym bro should stick to Test only and maybe a few orals. Trust me, all this other stuff isnt worth it if your just a gym bro. I been there and done that and regret taking Primo, EQ, Deca and Tren. Test, anavar and Dbol are the only ones I do not regret.
