About Tamoxifen
Tamoxifen is an estrogen-blocking drug (a SERM) approved as Nolvadex for breast cancer, sourced in research for estrogen-balance and post-cycle studies. It ships as tablets or a research-grade powder.
Its reported half-life is ~5–7 days (longer for active metabolite), which is the main reason the community cadence above looks the way it does. FDA-approved for the treatment and adjuvant treatment of estrogen-receptor-positive breast cancer, ductal carcinoma in situ, breast-cancer risk reduction in high-risk women, and McCune-Albright syndrome.
Reading Tamoxifen Capsule Listings
Capsule listings are ranked on total Tamoxifen per bottle — capsule count multiplied by milligrams per capsule — rather than on bottle price, because a cheaper bottle with fewer or weaker capsules routinely costs more per milligram. A capsule COA should test the finished capsule rather than the raw powder, and it should cover the exact capsule strength on sale.
Oral capsule formats differ from injectable vials in route of administration and bioavailability, so a Tamoxifen protocol written for one format does not transfer to the other. Confirm the vendor's COA covers the capsule product specifically.
