Speaking of rodent data, HEDs, AAS....
If you want some fun over the holidays keep it simple and take some time to try and make sense of the sum total (ok
alot of it) available literature data on testosterone; attempt to draw conclusions on any hard and fast limits for cumulative dose vs toxicity. You really have to read the last half of the thread in details for reference papers and how an envelope of chronic toxicity could be developed. Still very murky and long term data points are all anecdotal.
Did not get a lot of feedback at ExcelMale so perhaps there are folks interested here?
Of course that's taking some liberties (cherry picking the blue and red data points but FWIW. Ok, update to post #93 above. I took all the rodent studies with testosterone and combined with the PK modeling of this paper. Doing so allows me to take the calculated weekly mean HEDs in post 93...

The reason you probably aren't getting a lot of feedback (I'll give you mine - this looks initially very good, I am impressed by the work), is due to basic intimidation, but also
a substantial opacity to your methods and a certain gut instinct from many that these data might not mean much.
The "toxicity" outcome (really, outcome
s) is too generalized, encompassing disparate aspects of unfavorable side effects from Nand & T (e.g., cardiac dysfunction.... and autonomic dysfunction? I must admit that I don't know
anything about the latter aspect of T, and I'm more current on AAS research than many).
And of course, like you indicate yourself, even if we are to agree on an HED multiplier to start, it's simply not to be used in this manner because metabolism between species
especially on chronic time-frames (here, very long, terms of
years, in humans), where the crux of the data depends on AUC & the
very y axis of your amalgamated data, is in
person-
years extrapolated from rodent.
As you know, HED is to be used only to extrapolate an initial/early clinical trial dose in man without any more information. We have known for well over 6 decades what bioactive T or Nand doses are in man, so we
really have no reason to use HED in this manner at all.
IDK, I want to think we can do something with this, but it really strikes me as an ecologically invalid model.
