Aromasin vs Anastrozole for TRT?

ad

So for the past two years I’ve always been prescribed Anastrozole for my TRT, but it would seem that Aromasin has become the AI of choice for many people on cycle now a days. I got curious and wonder how many of you use Aromasin as your AI on TRT and how it compares to Anastrozole for you.

One of the reasons I’m thinking of asking my Dr about switching is because my lipids are a bit high as of last bloodwork. I just started taking fish oil and niacin to help get them back in range, but have read that Anastrozole can cause them to be high.

Just an update:
Doctor doesn’t want to switch to Aromasin, wants to keep me on Anastrozole for and play with the dosage and timing more.

I use Anastrozole when on TRT and Aromasin/Exemstane on Cycle, though I have it available if e2 gets out of hand when off. Both can crash e2, though Anastrazole can let you rebound easier, like shiva4 said. I inject 2x/wk, but I've had e2 problems in the past (possibly from low dose Clomid), 0.25-0.25mg of Anastrozole per week at injection times has kept everything in line for me on average-to-high TRT doses.

I have always preferred AROMASIN myself.

I just bought red yeast rice, niacin, and omega 3 oil. Hopefully that will help!

As of last bloods:
Triglycerides 126 mg/dL
HDL 54 mg/dL
Cholesterol 216 mg/dL
LDL 137 mg/dL
Non-hdl 162 mg/dL

Have you had any retests after the addition of these supplements?

Many physicians opt for anastrozole because it temporarily binds to the enzyme. Aromasin is a suicide inhibitor, meaning once it binds to aromatase it's done for. Anastrozole can lead to fluctuations because of the possibility of rebound but at the same time it can mimic natural physiological processes. This can be very beneficial if your estrogen ends up crashing at some point, there will be a shorter time before your body can return to a homeostatic level of estrogen.

Aromasin tend to be more expensive but anastrozole can effect a small.amount of people in terms of lowering cognitive function. Some physicians dont want to consider this but I can say from personal experience it definitely can for some people.

It all come down to what works best for you. It's really frustrating when a MD wont even consider trying an alternative medicine to see if that works better for the patient.

It comes down to trial and error to find the med and dose that works best for you in terms of balance and side effects.

Just out of curiosity, what is your sugar, fiber and alcohol intake typically?

Alcohol is rarely, and when I do it’s 2 “drinks” (1.5oz liquor) with dinner or friends. You don’t shoot the good stuff.

Fiber could use a little work tbh, usually around 30-40g.

Sugar I try to keep low, aim for under 100g.

Have you thought about lowering your TRT dose or if your bf is high lowering that also so don’t have to run an ai?

I have considered it. Bf hovers between 12 and 14% on calipers, and my body burns through test super quick. Day after injection I’m in the high 600s and by the end of the week I’m in the mid 300s. I lowered my injections to 150mg/wk and it did not go well, I became moody and felt like I was fluctuating too much. Dr bumped me back up to 200 and I haven’t had any issues. Also since my SHBG is so low, practically all my estrogen is free. Gotta keep in at the low end or it causes side effects even in the normal range.

Bi weekly injections? You could try a lower dose split e3.5d? I don’t really know much on the subject myself but I know that helps with fluctuations.

I have asked for aromasin for that exact reason. The response I got was that it isn't an AI they consider it a steroid which isn't approved for the treatment. I just shake my head. The problem we face with dr's are they parrot what the fda and big pharma say. A lot of these meds are not "approved " for men to use. I don't like anastrozole for the reason of rebound if you don't take it right or quit taking it. To where aromasin is suicidal. So when the does runs out you don't have to deal with all its captured enzymes being released.

I wonder if they could do an off label prescription for it. I’ll keep y’all updated on what my doctor says
