250 mg EOD actually works out to 875 mg/week.
with 100 mg tren and 100 mg drol ED you will be running 2275 mg of gear/week for the first 4 weeks. what is your cycle experience and stats??...cause thats kinda hefty.
running a-dex is sufficient, and 0.5 mg ED should keep E in check.....monitor how the dose is working, and adjust if necessary. since you know that you have pre-existing gyno issues, i would be inclined to bump it to 1 mg ED. keep the letro on hand as the anti gyno weapon of choice if you ever develop symptoms. hold on to the nolva for PCT.
your PCT is shit i must say. your exogenous test levels will still be pretty freaking high just when you are finishing (week 10). with sustanon, you may need to wait 3-4 weeks before starting your PCT. 40 mg Nolva ED is fine to use.
one suggestion i think you should consider......why not just run test prop with the tren?????????? you are pinning everyday anyways....so it makes more sense. you can finish up both at week 8, and hit PCT immediately. that would be a much better option IMO.
weeks 1-4: 100 mg Drol ED
weeks 1-8: 100mg Prop, 50-75 mg tren ED
