correct me if i'm wrong, but to my understanding:
Pro-hormones convert to an androgen. Steroids are already active compounds. Steroids are always more potent. Presently, almost every "pro-hormones" is NOT a precusor, and is actually and Oral LEGAL steroid. Superdrol, phera-plex, and epistane are straight up steroids. Theres not much difference between the strongest oral prescription steroid Anadrol and the legal OTC steroid Superdrol.
Testosterone such as the T produced by your HPTA, or Testosterone Enanthate, Sus, Prop, Cyp, or Cream are bioavailable and work/act exactly like T in your body with 1:1 anabolic/androgenic ratio.
Steroids such as Deca, Tren, Epi, Superdrol, Winstrol, D-Bol, ETC....they are NOT the same as using injectable regular T. These drugs are altered forms of testosterone, many of which have very skewed anabolic/androgenic ratio and estrogen conversion. Because of their totally different composition from actual Testosterone, they will exhibit substantial muscle gains, but are not entirely bioidentical which leads to side effects as the body cannot function smoothly on Trenbolone IN PLACE of natural testosterone as it would on Testosterone Enanthate IN PLACE of natural testosterone.
So, the longer you stay on a cycle of any steroids thats NOT regular T, the more you will shut yourself down, leading to more lack-of-real-testosterone side effects.
In this case, it would help tremendously to run some sort of injectable real testosterone such as Test-E, maybe only 100mg/week, along side your oral cycle. This will provide your body with the natural-T support that it will loose from shutting down while benefiting from the gains of the oral compound. DHEA breaks down into different hormones in the body, one of them being a SMALL amount of T. Therefore, its suggested the DHEA would help on mild oral cycles to alleviate shutdown side effects. I used DHEA with havoc and felt a tad bit better. However, my next cycle, if ever more powerful than 30mg of havoc, will include T as a base.
Using AI's, SERMS, and Herbal boosters, or ANYTHING thats designed to boost LH will NOT work on a cycle to provide natural testosterone. The LH will just be suppressed by the steroid, and using the AI/SERM will just crush/block more estrogen than necessary.
