Androstenedione, or 4-androstenedione (abbreviated as A4 or Δ4-dione ), also known as androst-4-ene-3,17-dione, is an endogenous weak androgen steroid hormone and intermediate in the biosynthesis of estrone and of testosterone from dehydroepiandrosterone (DHEA). It is closely related to androstenediol (androst-5-ene-3β,17β-diol).
4-Androstene-3,6,17-trione. 4-Androstene-3,6,17-trione ( 4-AT; also marketed as 6-OXO or 4-etioallocholen-3,6,17-trione) is a drug or nutritional supplement that may increase the testosterone-estrogen ratio, but has no proven effect on body composition. Its use can be detected in urine.

ATD has many names in sports supplements including: 1,4,6 etiollochan-dione, 3, 17-keto-etiochol-triene, androst-1,4,6-triene-3,17-dione and many others. These all refer to CAS# 633-35-2. ATD may cause a positive test for the anabolic steroid Boldenone, of which it is a possible metabolite and production contaminant. ATD is also prohibited in ...
Androsterone, or 3α-hydroxy-5α-androstan-17-one, is an endogenous steroid hormone, neurosteroid, and putative pheromone. [ 1] It is a weak androgen with a potency that is approximately 1/7 that of testosterone. [ 2] Androsterone is a metabolite of testosterone and dihydrotestosterone (DHT). In addition, it can be converted back into DHT via ...
In general, the risk of side effects from finasteride is low. Research shows the vast majority of men who use finasteride over the long term benefit from a successful hair loss treatment with few ...
Mesterolone. Mesterolone, sold under the brand name Proviron among others, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels. [ 2][ 3] It has also been used to treat male infertility, although this use is controversial. [ 2][ 4][ 5] It is taken by mouth.
Androstanedione, also known as 5α-androstanedione or as 5α-androstane-3,17-dione, is a naturally occurring androstane (5α-androstane) steroid and an endogenous metabolite of androgens like testosterone, dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), and androstenedione. [1] It is the C5 epimer of etiocholanedione (5β ...
