pa1ad said:I think you are missing alot of knowledge in this area and you make incorrect deductions from what facts you do know. The in-vitro blood study showing 15% conversion really means little in regards to what activity the 4-AD has in the body. It disregards conversion at target tissues and intrinsic activity. The assays of 4-AD done on rats showing high activity tends to suggest that things are going on with the compound that are not obviously apparent from simple testosterone conversion in the blood.
But it does allow for a decent comparison between different compounds, no ? Otherwise why use such studies to document anything ? ok, question : Since the other prohormones convert by similar pathway, would they not show similar conversions (as 4AD) in other tissues as well ? And what else can we possibly go on, because I doubt anyone will take it upon themselves to measure the conversion in ALL tissues.
Your determination of 14% bioavailablity from urinary excretion studies also displays ignorance of pharmacology on your part. What shows up in the urine is not what determines bioavailablity, rather, it is the percentage of compound which makes it to the blood. What shows up in the urine is often completely irrelevant to bioavailablity
ok, bad choice of words, but it does show how much of the stuff makes it through the liver and into the blood after hepatic breakdown and it does once again offer a base of comparison.
You may also want to think that a good transdermal delivers alot of steroid, but unless you can offer some evidence of that beyond telling us that your delts swelled up then please stick to what the scientific literature tells us
Fine, but two can play that game. You may think that 4AD has a higher conversion in other tissues, but unless you can offer some evidence of that beyond telling us that, then please stick to what the sicentific literature tells us ? (I may be "ignorant" and "lacking knowledge" in your book, but I do pay attention.
so back to the books Big Cat
I guess the same holds true for you I await your reply to my question.
