I have no idea where you got the theory that testosterone is twice as anabolic as DHB. We have no studies on humans, and studies on rats have shown that in theory its twice as anabolic as testosterone. Apart from the fact that this rat test is flawed, of course
We also know that stenbolone reacts with 3alpha HSD like DHT, masterone and primo, which neutralizes the strength of the compound in the muscles, but I dont have data to what extent it does it. For comparison, it seems to me that DHB also reacts with 3alpha HSD, but it does so to a much lesser extent than the three above-mentioned compounds
maybe an expert
@Type-IIx will tell us something more
Everything you state here is correct.
From metabolism studies, it is extensively 3α-reduced, its primary metabolites including 3 alpha-hydroxy-2-methyl-5 alpha-androst-1-en-17-one & 3 alpha-hydroxy-2 xi-methyl-5 alpha-androst-17-one.
Where it does claw back some theoretical potency is by its 2α-methylation, that ↓androgenic & ↑anabolic activity, slowing the rate of ring A reductions... in 5α-andostan-3-one steroids, this would be confirmed by greater number of metabolic steroid products retaining the 5α-andostan-3-one system... and in actuality it does do a fairly good job at this:
Firstly, its primary metabolite is itself, reflecting some resistance to metabolism.
Secondly, stenbolone's intermediary metabolites 16ξ-hydroxy-stenbolone & 16ξ-hydroxy-2-methyl-5α-androst-1-ene-3,17-dione do maintain the 5α-andostan-3-one steroidal core that provides the 3-keto group whose lone pair of electrons serve to accept H-bonds permitting it to form a strong bond with the AR's N-terminus/amino-group & aydrophobic backbone with good flatness (less bulky than T) to fit into the hydrophobic cavity of the binding site on the AR.
Practically, stenbolone is a good AAS, that is patented for human use, being
originally introduced by Schering AG in Germany in 1961, then by Syntex UK in 1963. Duchaine referred to stenbolone as his "sentimental favorite," referring to the (no longer commercially available) Farmacologio Latino 25 mg/mL. As of July 3, 1991, records indicate that Merck holds the registration for producing stenbolone, if it so chooses.
It is practically equivalent to metenolone ("Primo") & drostanolone ("Mast"). It is, like those counterparts, an androst-1-ene-3-one, that Duchaine refers to as being applied commonly at 100 - 200 mg weekly doses, and remarked that it is "reat for cutting, especially for women (low androgenicity)," & augments RBC/HCT/Hb on par with oxymetholone, which is, also, consistent with its counterparts.
I’ve had
@Type-IIx chime in on this same topic before. He agrees with what I’ve said.
I never said twice as anabolic, but a study on rats, mg for mg, showed:
1. Approx 20% more LBM increase from Test P vs DHB
2. Increase in liver weight in the DHB group.

Don't take anything I said out of context please.
Rodent (Hershberger) Assays are not at all reflective of human biological effects, in no small part because the vastus lateralis in rat is in fact the dorsal bulbocaverous, a sex organ, therefore, both anabolic & androgenic ratings derived from it do not actually distinguish between androgenic vs. anabolic activity. The assay is useless. I am
certain that I also qualified the "liver size increases" as almost certainly inapplicable to man, but interesting on a background of liver changes by AAS in rodent being quite unusual.
I don't accuse anyone of intentionally misreprestening my statements, but I always am misquoted it seems when my posts are not referred to explicitly by quote (copy & paste from original thread) & links to the relevant portions of a thread.
Please, I only ask that you use this good practice for citing my writing in the future.
