use the nolva, you already have it.
grab hcgenerate ES and some liquidex for pct. liquidex being an AI should help with any gyno that may of possbily developed & it will work very well with hcgen ES.....by stopping any conversion of tes to E.
osta should be used too, dbol is awesome for strength gains, but once its gone.......your strength is too. Osta will keep strength up as much as anything will. Just dose the hcgen ES hi and maybe even add d spark. The key here is to have lots of LH/FSH production and still be able to counter that tab bit of supression the osta will cause.
so, yes, osta will cause a tiny bit of supression, but thats is necessary to keep gains and allow them to mature for another 4-6wks. Rome wasnt built in a day, nor a month. Muscle growth is very similar. It takes a lot of time and proper diet/training. So having a great pct, with a sarm is almost going to be an extension of the cycle itself.
the last thing you want is great gains for 4wks and to fall on your fact in pct. You need to keep things going and to do that is going to require a good serm and T boosters......which will still product lots of LH/FSH production and allow the osta to produce strength gains.
you could also run some LGD for 4wks before the dbol, than dbol for 4wks, than a great pct for 4-6wks after that. those 12-14wks should and will (provided your doing whats necessary) put weight, strength and allow for some fatloss at the end of the day.
I would consider buying a few more items to make these 12-14wks a whole lot more anabolic than your currently have.
