Nice skeleton pics though.
Damn, beat me to it.superdrol is missing the 17b-OH (in your image)...nice otherwise

This has been covered many times on this board.Halodrol is not active. It needs to be converted, (therefore it IS a prohormone):
Halodrol:
4-chloro-17a-methyl-1,4-androstadiene-3,17b-diol
notice it's a diol, so to convert to its target hormone, the 3-ol needs to become 3-one (via 3b-HSD).
so the target hormone would look like this:
4-chloro-17a-methyl-1,4-androstadiene-3-one-17b-ol (Turanibol)
3,17 have their own activity though, and Ziquor explains it nicely here :

Remember, testosterone is a "prohormone" to DHT, but has it's own activity when binding to the AR.
When I 1st got into checking out the chemistry of PH/PS's, I assumed that a PH or a PS was basically a weaker version of its parent, but the same nonetheless.
Also the amount of the hormones 'own' activity or pre-activity seems to vary from one compound to another. This may be due to the compounds RBA for each receptor.
Would you consider Halodrol to be a Prohormone or a readily active Steroid?
Many people seem to think H-drol is both a pro-steroid to OT and is somewhat active on it's own...don't know if that's ever been conclusively proven though...
(And by active, I mean, can bind ARs without any conversion and activate AR-dependent signaling...)

I assume H-Drol may be good for someone who had a long layoff?
Yeah I know. However the majority of the activity comes from the conversion to OT. I stated (which IMO it is) that it is Prohormone as oppose to a steroid and then someone disagreed. I suppose a pro-steroid is an accurate term for it though.
The 17beta-hydroxy (17b-ol) enzyme allows binding to the androgen receptor.
Thus all 3,17-dione and 3,17-diol hormones bind to the androgen receptor before converting to the target hormone. The pre-activity is usually slight, yet enough to give the compound a slightly different profile & 'feel' than their target.
I understand what you're trying to say regarding prohormones, and I'm assuming when you say "steroids," you're referring to "highly active" steroids. Prohormones are steroids by the very definition, just typically not as strong as the intended parent compound.I am not a chemist but this is how I see it:
Halodrol converts to oral turanibol.
All original prohormones are basically precursors to known steroids.
Original 1-AD is a precursor to 1-test
Original 4-AD is a precursor to testosterone
Halodrol(and clones) is a precursor to Turanibol
The fact that it has mild activity cannot (IMO) be compared to testosterone
I look at Halodrol to be a Prohormone as the majority of it turns into a target hormone oral turanibol
This is sort of right, but sort of not. It's the 17b-OH group ON the steroid that allows AR binding (and is pretty much required for efficient binding and activation). The enzyme 17b-HSD converts a 17-keto (C=O) to a 17b-OH (17a-H).
I would say diols are more likely to bind the AR without conversion, but this will depend on the structural features of the A and B rings. Often though, diols don't bind very well either. But this is good for H-drol, which seems to have a good A ring structure for this (the 4-Cl maybe?). But I don't think you can generalize across compounds.
Anyway, not trying to argue or start a pissing match, so please don't take it that way. I felt like I was getting a little attitude from some of your replies...I almost didn't post this. Forgive me if I misinterpreted...
