Thread: Aromasin or Arimidex?

  1. #1

    Default Aromasin or Arimidex?

    During this cycle:
    Weeks 1-4: Test Prop @ 100mg EOD
    Weeks 1-10: Test Cyp @ 400mg Every week
    Weeks 7-12: Winny @ 50mg tabs ED

    Weeks 1-12: Aromasin or Arimidex...

    Which AI is acceptable and at what dosage? Not trying to deplete body of estrogen or water, just keeping it at bay.
    I already have Aromasin.

    PCT is Nolvadex @ 20/20/10/10/10mg ED

    Either is fine. Never run aromasin so cant tell you about dose. As for anastrozole I run 1mg eod but it looks like you will be running a lower test dose so .25mg eod will be fine to start. If you notice a lot of water retention up it to .5 eod.

    Run the Aromasin for shure!!!!!!!!! Your gains will be better. Bigtime. A-dex is known as a suicide AI. It will suck ALL of the estrogen out of your body. Thats a bad thing.

    I thought it was the other way round?

    Yeah its the other way around. Aromasin is called the suicide AI because it actual kills the receptor cites. They are not gone forever though as your body will make more eventually. Studies have found that 25mg of aromasin can lower estrogen levels by 85%.
    As for anastrozole one study by Zeneca Pharmaceuticals found that .5mg and 1mg doses of Arimidex were shown to decrease estrogen by roughly 50%. The 1mg/day dose also increased testosterone levels by 58%. So I am really confused by all the talk on this board lately about Arimidex completely shutting down estrogen production. It’s not true sorry guys.
    And in case you were wondering Letrozole has been shown to reduce estrogen levels by 98%.

    I've done the reading and came up with equally fought battles arguing both parties.
    Who knows....

    How is that possible? I thought higher levels of estrogen meant higher levels of test...due to the feedback loop etc. Body senses high level of Est, so produces more Test to counter it.
    I may be wrong, this was the impression i was under and have been for a while.

    Here is the study:

    J Clin Endocrinol Metab 2000 Jul;85(7):2370-7, "Estrogen Suppression in Males"

    We have shown that testosterone (T) deficiency per se is associated with marked catabolic effects on protein, calcium metabolism, and body composition in men independent of changes in GH or insulin-like growth factor I production. It is not clear,,however, whether estrogens have a major role in whole body anabolism in males. We investigated the metabolic effects of selective estrogen suppression in the male using a potent aromatase inhibitor, Arimidex (Anastrozole). First, a dose-response study of 12 males (mean age, 16.1 +/- 0.3 yr) was conducted, and blood withdrawn at baseline and after 10 days of oral Arimidex given as two different doses (either 0.5 or 1 mg) in random order with a 14-day washout in between. A sensitive estradiol (E2) assay showed an approximately 50% decrease in E2 concentrations with either of the two doses; hence, a 1-mg dose was selected for other studies. Subsequently, eight males (aged 15-22 yr; four adults and four late pubertal) had isotopic infusions of [(13)C]leucine and (42)Ca/(44)Ca, indirect calorimetry, dual energy x-ray absorptiometry, isokinetic dynamometry, and growth factors measurements performed before and after 10 weeks of daily doses of Arimidex. Contrary to the effects of T withdrawal, there were no significant changes in body composition (body mass index, fat mass, and fat-free mass) after estrogen suppression or in rates of protein synthesis or degradation; carbohydrate, lipid, or protein oxidation; muscle strength; calcium kinetics; or bone growth factors concentrations. However, E2 concentrations decreased 48% (P = 0.006), with no significant change in mean and peak GH concentrations, but with an 18% decrease in plasma insulin-like growth factor I concentrations. There was a 58% increase in serum T (P = 0.0001), sex hormone-binding globulin did not change, whereas LH and FSH concentrations increased (P < 0.02, both). Serum bone markers, osteocalcin and bone alkaline phosphatase concentrations, and rates of bone calcium deposition and resorption did not change. In conclusion, these data suggest that in the male 1) estrogens do not contribute significantly to the changes in body composition and protein synthesis observed with changing androgen levels; 2) estrogen is a main regulator of the gonadal-pituitary feedback for the gonadotropin axis; and 3) this level of aromatase inhibition does not negatively impact either kinetically measured rates of bone calcium turnover or indirect markers of bone calcium turnover, at least in the short term. Further studies will provide valuable information on whether timed aromatase inhibition can be useful in increasing the height potential of pubertal boys with profound growth retardation without the confounding negative effects of gonadal androgen suppression.

    Very interesting. Interesting that LH was increase....but IGF was decreased whilst Test was increase. Thanks Hart.
