Tamoxifen 20mg: pharmaceutical gradeTamoxifen (Nolvadex) Research Areas
- Restarts natural production: Blocks receptors at the hypothalamus and pituitary, raising LH and FSH
- Gyno treatment: Blocks the receptor where the problem actually occurs, an AI only lowers circulating oestrogen
- Better tolerated: Generally easier to run than clomid, without the visual side effects
- Catch it early: Established fibrous tissue does not respond to any drug
How Tamoxifen (Nolvadex) Works
Tamoxifen occupies oestrogen receptors selectively. At the hypothalamus and pituitary that restarts the axis; in breast tissue it prevents oestrogen acting where gynecomastia develops.
That second property is what separates it from clomid and from any aromatase inhibitor.
Tamoxifen vs an Aromatase Inhibitor
An AI lowers oestrogen throughout the body and is the preventative tool while aromatising compounds are running. Tamoxifen blocks the receptor and is the treatment tool once symptoms have started.
Note that prolactin-driven gyno responds to neither, that needs a prolactin test and a dopamine agonist.
