Thinktank let me try to explain. There is a functional difference between an anti-aromatase (like Arimidex) and an anti-estrogen (like Nolvadex). Nolvadex blocks the estrogen receptor but does NOT prevent estrogen from forming in the body and Arimidex (as does Aromasin and letro) actually stops excess estrogen from forming (stops aromatization). So Nolva-Clomid are blockers more than stoppers of estrogen formation. Also clomid was never intended as an anti estrogen, it just "acts" like one. The negatives when taken longer term vs short term as in PCT: Nolva and Clomid raise SHBG, raise LDL, lower IGF-1(nolva), and affects mood negatively. Which is counter to what your trying to accomplish.
I don't recommend it. But if that is all you got you can use Nolvadex. Just keep in mind when you stop using it you will have a rebound effect as the estrogen is still there.

you dont eat dude '
its to much iso protein shake

how bout this
8am 1 cup oatmeal (cooked), 2 cups milk and three eggs

11am turkey sandwich 2 cups milk and some fruit

2pm another sandwich or pasta , some meat servings (2) and lots of water with vegetable and some potato source or similar

5pm pre workout small meal of protein and carbs

7pm post workout protein shake and something else with fats and carbs ,
8pm DINNER BIG MEAT and CARB DINNER

11pm last meal maybe yogurt or popcorn, even another sandwich

^ this is just an example of a moderate actually mild bulk diet
you simply do not have enough calories to build muscle at 1900cals
i eat 1900 cal breakfasts

for example
2cups milk
2 yogurts
large bagel cream cheese
5 eggs and three large pancakes
i sometimes put some peanut oil into the milk and its like 2000 cals

then lunch would be like 12oz of roast beef, sliced sirloin or chicken/fish, 12oz plus whatever meat you want and like two cups yellow rice, one cup black beans with some toast garlic bread or something\ 3 cups milk

dinner is another large meat portion with protein enriched pasta and vegetables

then dessert is like brownies and or maybe a bowl of cereal, whatever is 500 cals, and two cups milk

i try to eat smaller meals in between and maybe drink one protein shake per week maybe two ...your drinking multiple per day and not processing it like you do food protein sources

the above works for my purpose
im under 10% BF and bout 180 , 6ft
this may be too much for some as its 4-6000 cals
but last time I checked Im bulking and have to reach my goals so i force myself

the op
doesn't seem to understand calorie surplus

When you say you eat 2300 calories what does your meals consist of? I stay under 10% bf even when bulking and honestly I'm probably at 2300 calories by meal 3 of 7. If you will list examples of your average daily meals I would love to help you out bro.

take my offer below ill make you gain lean mass , with aas or not...its diet and meal planning that you ned
ill tell you how to manipulate the intake by timing certain food with natural hormone production and watch you grow ...if you follow it.
10lbs in 45-60 days , of per lean mass,keeping it because it is food(lean muscle tissues) gains which are the most easily kept gains and what we desire ...
opposed to PED gains(which can be kept to), water(often lost), adipose(who wants that),bone(not gonna happen,gyms dont make you taller)

Gator let me answer this one because I've been seeing this a lot lately. Thinktank your on 500 mg a wk of Test. Your at 19% body fat. You do know when you added that extra Test to your body that a portion of it is converting to estradiol by aromatase enzyme which by the way is plentiful in body fat. Not everyone experiences sides with high estro. If you have high(estradiol) you will experience weight gain(fat). It offsets the effects of testosterone. It is the reason why women carry more body fat than men. They have higher estrogen levels. I bet a dollar that if you got a blood test it would show your estadiol is high. I can almost guarantee it. How do you know if that gear isn't working. How do you know if your dialed in? If there's one thing I have learned thru the years is that everyones body chemistry is different. I'll answer those questions for you. You don't know, you can't just go by feel. You really want to know whats going on get a blood test. But again I think your problem is your estradiol is to high and until you get it in check your spinning your wheels. It really comes down to simple body chemistry, no AI and that testosterone is being converted to estradiol and that's a fact.

oh really its not the 1700 calorie per day diet it the oils being bunk
interesting concept of self neglect of the real problem
your girly lil Cinderella diet and training Regime
"if 2300 cals makes you fat"
then your doing it all wrong dude
im about 9-10% bf and 177-180 at 6ft tall
i eat 4-6000 cals per day and train every other day for 1hr and 15 mins
and sleep and dont drink alcohol
so what am i doing so different than you, and us i understand people bodies metabolisms are different i work with health related clients daily
but what im saying is please get real
learn from eroids and other sources about diet and nutrition
PM me and lets discuss your goals and concepts
might seem like im coming off hard but its because im mad about the situation your in bc i can understand it and the problem is obvious to me and ill help you right the wrong so to say
if you care too that is

Get bloodwork done to be sure, but it's possible.

Nice heavy weights, and slow burn, agonizing sets focusing on form and sheer weight over reps and speed. Maybe cut out the cardio altogether for a week or two and see how that goes for you. I eat like a horse and skip cardio
