Growth will work as soon as you start using it. Its just that the actuall gains accrued as so small then you only see a small difference.
The theory that it doesn't start to work til after 8 weeks is completely nonsensical. The guy is ruinning it for 7 weeks and it will make a difference. A small one bu nevertheless it will have an effect. Its not like your body says 'RIGHT I'VE BEEN ON THIS STUFF FOR 8 WEEKS NOW, BETTER START DOING SOMETHING NOW' Growth is growth, it starts to do its thing as soon as you put it in. In medicine its usually used for 30 day periods for burns treatment and it works. I think the problem is that people expect too much from growth. Its no magic bullet, but it will help get past plateaus. If you are not competeing then thats why I would say save your money.
Also Proviron doesn't do the same thing as Nolvadex, Nolva's block estrogen receptors in breast tissue. Proviron prevent the aromatase enzyme from converting test to estrogen.
I'd run the proviron (or A/dex) from start of week 4 till end of week 8.

Finally, i'd agree with LeeB, drop the Oxy, the potential for incuring side effect is too great, much better off using stromba's.

Everything else appears to be okay. But as Lee also said, make sure you've got you PCT and Detox in place, coz you'll need it.
