1) Why are you going up to 750 mg/ test week? I suggest go back down to 500/week. Additional test isnt going to increase as much as you think, just more of it will aromatize into estrogen which is why gyno is flaring up for u. a (AI) will slow the conversion, but u still need estrogen for gains, thats why they say it hampers ur gains. A SERM will block the receptor at the site, but not block the conversion process. a low dose nolva (10mg day) would be good also instead of the AI (with the lowered dose of test you wont need it)
2)Dont add tren, especially since its ur 3rd cycle of pure test no need for the binding power of tren. Tren is very potent and strong binding, and will wear out the receptors thats why its A) expensive, and B) it works. You should add a different compound depending on what you want to accomplish but definately hold of on tren.
3)Dont go from 750/week to 250/week, stay at a even keel. Although 250mg/week is greater than a TRT dose, the drop in dosage will be to fast for your body to compensate and estro-related sides will increase due to the increased conversion and such.
FYI *to cover my ass :P* you do run a elevated risk of having HRT(cuz ur young, and can cripple ur natural test) as u get older because you cant produce anything naturally. Make sure your PCT is squared away, and wouldnt hurt to throw some HCG in there to help keep balanced
oh and diet and work outs are key
