Description:
In medical studies measuring blood estradiol and testosterone levels of hundreds of individuals, letrozole is a very consistent-performing drug with almost no unusual behavior. The only unusual behavior to be found in scientific literature is in a very early publication by the pharmaceutical manufacturer which made it appear unbelievably potent, but left out many details. All other studies have shown rather ordinary and consistent potency.
My own findings over more than 10 years have matched up with these results.
The other story will be that even trace doses of letrozole will “obliterate” estrogen and that it’s very tricky to use for this reason.
Obviously, if that’s your personal experience using a given letrozole product, go by your experience. If however you are new to letrozole or have used it successfully before, then I recommend that you consider it no greater in dosing difficulty than any other aromatase inhibitor (AI), as this is my experience with very many individuals.
