1,4,6-Androstatriene-3,17-dione(ATD,androsta-1,4,6-triene-3,17-dione)is a potent irreversible aromatase inhibitor that inhibits estrogen biosynthesis by permanently binding and inactivating aromatase in adipose and peripheral tissue.It is used to control estrogen synthesis.

ATD is present in some over the counter bodybuilding supplements as well as Topical ATD solutions that work transdermally.While not banned,ATD may cause positive urinalysis results leading to disqualification from competitive sports.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.

ATD may cause a positive test for the anabolic steroid boldenone,of which it is a metabolite and is also prohibited in amateur and professional sports which forbids aromatase inhibitors.


ATD inhibits estrogen biosynthesis by binding and inactivating the aromatase enzyme.Also,it naturally increasestestosterone levelsby lowering its conversion to estrogen.Higher testosterone levels typically mean increased strength,muscle,and a decrease in body fat.


Bodybuilders and athletes will use the ATD cycle to help permanently disable aromatase.This can prevent estrogen-related side effects such as men's breastfeeding(bit),excessive water retention,high blood pressure and insomnia.

Another benefit of ATD is that it has 90%of androgen activity in muscle tissue and only 10%of androgen activity in the hypothalamus.Therefore,theoretically should be used to keep it more muscle.In addition,ATD prevents negative androgen feedback loops,which will reduce estrogen production while increasing testosterone production.


On asteroid cycle,shutdown occurs when the pituitary glands go dormant,and no longer produce LH(luteinizing hormone).It is LH that stimulates the testes(leydig cells)to produce testosterone.When an athlete is usinganabolic-androgenic steroids(AAS)with ATD,it will reduce‘shutdown’and help disable the estrogen enzyme,so very little estrogen rebound will occur.

There is a split in the bodybuilding community as to whether ATD should be used for PCT,or not.Some will not recommend ATD to be used duringpost cycle therapy(PCT)because of the possibility of interfering with natural testosterone and the HPTA.However,some feel as though it aids in recovery by boosting testosterone and decreasing estrogen after cycle.Both uses are possible,but the quality of ATD on the market remains unknown.Therefore,be warned when considering using ATD,especially from non-approved suppliers.

Side Effects

Studies have shown that ATD may inhibit sexual desire and sexual function,which may be related to the reduction of estrogen.ATD(aromatase inhibitor)can also be used at any time,so do not abuse the compound.


The dose range is 25-100 mg per day for 4-8 weeks.Those who choose to run ATD during post-cycling therapy should use it as a kickstart.If used alone,it is important to pay attention to the level of blood work.You never expect estrogen levels to fall too low.


ATD is a powerful suicide aromatase inhibitor,temporarily on the counter.It can be used during circulation,independent or post-circulation therapy.It treats estrogenase as usual with aromatic hormones and prevents bouncing after the cycle.However,the quality of ATD is still a major problem in the industry.After many government attacks on ATD vendors,I will not recommend trusting anyone who sells his supplemental version.
