5-AA (5-alpha-androstanediol)
Target Hormone: 5-alpha-dihydrotestosterone (DHT)
Molecular name of target hormone: 5-alpha-androstene-3-one,17b-ol
Target conversion: low, needs to undergo 5,4-isomerase prior to conversion, and only a small percentafe survives the liver. Estimated 0.15%.
Conversion enzyme: 3-ß-hydroxysteroid dehydrogenase (3HSD)
DHT conversion: Very High, converts directly to DHT
Estrogenic effects: None whatsoever
Often 5-AA has been called a precursor to the hormone Masteron (Dromostanolone), a fact that has been happily exploited by one manufacturer that used a similar name and is guilty of setting a bad example by naming his product after a steroid. In effect, Masteron has an extra 2-alpha methyl group. 5AA does not. Masteron is also known as 2-alpha-methyl DHT, or DHT with an extra 2-alpha-methyl group. 5-AA really a precursor to DHT. 5AA is actually a prohormone naturally produced in the body as a response to low levels of DHT. Using the 3HSD enzyme it is capable of restoring androgenic capacity if it is hindered.
1,4-andro (1,4-androstadienedione)
Target Hormone: Boldenone (1-dihydrotestosterone)
Molecular name of target hormone: 1,4-androstadiene-3-one,17b-ol
Target conversion: moderate to high, estimated just over 10 %
Conversion enzyme: 17-hydroxysteroid dehydrogenase (17HSD)
DHT conversion: some conversion
Estrogenic effects: aromatisation of the prohormone
Definitely more promising than the 5-AA. I found it has great resemblance to the 1AD in the fact that it has no estrogen aromatisation possibility, assures almost all gains as dry weight and the double bond at the one position which ensures greater oral activity without extra liver toxicity. However, Not here, nor on the 5AA by the way, was there any kind of study attached showing the efficacy of either product. It is touted as a precursor to boldenone, another popular steroid and pre-contest hardening agent. In this case there is more truth in it. Only that boldenone has a hydrogen and oxygen bonded and the 1,4-andro has a double bonded oxygen atom. Boldenone becomes methandrostenolone in its methylated form, also known as Dianabol, possibly the most popular oral steroid in the world, ever
