No problem my friend:
GW - 12.5 mgs ED. Split in two dosages. One taken in AM, the other one taken before working out or PM
S4 - 25 mgs per day for the first two weeks, and then increase the dosage to 50 mgs till the end of the cycle. Split the dosage in two, like with GW
Ostarine - 25 mgs per day, split the dosage in two.
N2Guard - 5 caps per day will be plenty.
There is no need to use AIs with SARMs, as they do not aromatize into estrogen, so you will be fine in this regard. For mini-PCT you will need clomid, nolva, HCGenerate ES and Ostarine. Check it out here in detail -

Good luck with the cycle!
