Prima di chiudere il libro su Aromasin, vale la pena notare che è possibile (e dovrebbe) still use one of the non-steroidal AIs during your cycle to reduce estrogen , Se necessario. Quando si è pronti per PCT, si può poi passare ad Aromasin e ancora sperimentare gli effetti di un'intelligenza artificiale, since there is no cross-over tolerance experienced between steroidal and non-steroidal AIs (9). Poiché si tratta di Aromasin 65% efficiente a sopprimere l'estrogeno (10), it’s certainly a very powerful agent , especially considering you won’t experience reduced effectiveness because of your concurrent use of Nolvadex or from any sort of tolerance developed by using other AIs on your cycle (9). There is also a decent amount of preclinical data suggesting that Aromasin has a beneficial effect on bone mineral metabolism that is not seen with non-steroidal agents , and it may also have beneficial effects on lipid metabolism that are not found in the non-steroidal Letro and A-dex (9).
