"Iï¿½??ve always been in favor of using Nolvadex during PCT, along with an AI, because reducing estrogen levels has been positively correlated with an increase in testosterone (7) so in my mind, itï¿½??s be beneficial to increase testosterone by as many mechanisms as possible while trying to recover your endogenous testosterone levels after a cycle. SO which AI do we use? Letro or A-dex? Well, why donï¿½??t we just keep using whichever one we used during the cycle, and add in some Nolvadex? Unfortunately, Nolvadex will significantly reduce the blood plasma levels of both Letrozole as well as Arimidex (8). So if we choose to use one of them with our Nolvadex on PCT, weï¿½??re throwing away a bit of money as the Nolvadex will be reducing their effectiveness."
This, of course, is where Aromasin comes in, at 20-25mgs/day.
"Aromasin, at that dose, will raise your testosterone levels by about 60%, and also help out your free to bound testosterone ratio by lowering levels of Sex Hormone Binding Globulin (SHBG), by about 20% (12)ï¿½?ï¿½SHBG is that nasty enzyme that binds to testosterone and renders it useless for building muscle. But what about using it along with Nolvadex for PCT?"

I much prefer a 11:7 ratio..... it doesn't matter, it's all preference.
Stick with an AI during your cycle at a low dose, and a serm for PCT like Nolvadex. You do not want an AI post cycle unless you are doing something to raise estrogen conversion like taking relatively high-dose Hcg (+500iu/day), but hcg is faired better during your cycle anyway in my opinion.
But most importantly, get all aspects of your goals in order before running another cycle. If your diet and training aren't up to par you will have sub-maximal gains and lose most of them anyway.[/quote]
