Been on Letro for 5mg, 2.5, 2.5, 2.5, 2.5. Drive has seemed to go up(test/tren cycle), bloat is gone. Funny thing, the 1st day, bloat seemed worse. Just wondering again, what is commonly taken? This shit is expensive, and would like to take the min necessary. T1/2 seems to be around 48-52hrs.

from my experience letrozole is much more powerful than arimidex.. i used both the UG labs version and the astra zeneca straight from the pharmacy.....when i got gyno for the firs time in my life last cycle, letrozole literally made it dissapear in one week. as far as dosage , i never had to take more than 1.25mg/day (half a cc) ..with 500mg of test.

I agree. I am an aromasin fan over arimidex. Letro is a bit different.
While no ones has asked yet, tamoxifen (i.e. Nolva) will lower IGF-1 levels considerably, thus, it is probably not the best choice unless you really need it, i.e. gyno symptoms.
Arimidex is non-suicidal, which means that a high enough level of androgens will displace it from the receptor sites. This makes it great for low to moderate dose cycles, but ill suited for moderately high and high dose cycles. It does have a long half life, so EOD administration usually is very effective. It is commonly dosed at about 1mg EOD for every 500mgs per week of aromatizable androgens the user is taking. The downside is that it will also lower IGF-1, not as severely as Nolva, but a noticable little bit. A decent choice for lower dose cycles for those on a budget, thought it has been used successfully by many for just about any cycle.
Letrozole (i.e. Femara) is a newer (improved?) version of arimidex, with the primary difference being a shorter half-life which necessitates ED dosages. The big advantage with this one is that it supposedly will not lower IGF-1 levels. The common dose usually runs about 2.5mgs ED.
Aromasin, my choice as mentioned above. It is a suicidal aromatase blocker, thus it is not displaced by a high level of androgens as is arimidex. This is the best that i know of, but its very pricey and hard to find. Its effects on IGF-1 levels are less than arimidex, but higher than Letrozole. The primary downside to this one is that the price is usually considerably more. The common dose is usually 25mgs ED, regardless of the amount of androgens that the user is taking. I have found it to be so effective that I have switched to an EOD dosing schedule myself.
I also forgot to mention that both Arimidex and Letro have a negative effect on cholesterol levels and well as libido (primarily letro on the second one). Aromasin does not have the negative effect on cholesterol or libido (or at least not a significant one). I am not a MD, but I dont think the cholesterol effect would really matter for the short time one would be taking these anyways, but I thought I would mention it.
I was reading on another board that arimidex and letrozole lowers libido. This was someones personal experience. I havn't used either of them before so I don't know fo sure. On 800mg of test a week I doubt there will be libido problems anyway, the only problem might be having to piss with a hard-on.

make sure you have nolvadex for the drol, letro may be a bad idea for this cycle as letro lessens the power of nolvadex. Go with liquidex or better yet aromasin like I said before.

I believe that it was recently found to be false. At best you are working on speculation, nolva is your best option as it is site specific. Nolvadex may even help a bit for progesterone gyno, but it is definitley not the first shoice there. This is why (for now atleast) I only use d-bol to kickstart a cycle.
I have nolva as it is and I'm going to be picking up the letrozole. You say Nolva as being site specific but so is Letrozole according to what I've read. I'll take your advice adn just to be safe I'll run both of them whil I'm on the drol, then just continue with the Letro after that.
