Ah, yes, my bad AnUser. I misunderstood what you were saying.
Indeed, most would prefer routes without having to jab a needle into yourself. Self injections are hardcore.
I see now, it’ a c-max value that Bicep was referencing and not a percentage. That makes a lot more sense now. Achieving 7x of your c-max is a lot different from 7x the percent bioavailabilty. My bad, Agetron.
To explain what is happening here, I’ll have to show this chart:

The t-max is simply the time after a dose at which the concentration in blood is at its highest. The value he gave, being 38.2 ng/mL, is the c-max, or the maximum concentration in blood at the t-max.
When you stated an increase in the percent bioavailability, I thought you were talking about the AUC - area under the curve. This is typically what biochemists refer to when saying “percent bioavailability”. That was a misunderstanding on my part when you stated a percentage.
You see, if you derive the area under the curve you can calculate the total amount of drug that was actually absorbed into the bloodstream. So, having a 7x increase in the c-max doesn’t mean you increased the bioavailability by 7x. In order to determine that accurately, you need a LOT more data points in order to fit a curve and derive the AUC.
Now, that is not only expensive and tedious to do, but also quite difficult. I’m surprised that Agetron has a PCP that allowed him to do back-to-back blood draws like that, pretty cool! But I think even his PCP would balk at the idea of taking 12 or more blood draws spread across a single day. So, it’s better to simply look at the peak and trough level as a rough estimate of the increase in bioavailability. You can only plot a triangle on the chart, but it still gives you an idea of how much more you’re getting out of each dose.
That sounds like a reasonable action. Hopefully when he returns, he will have a different perspective on his drug use. I genuinely wish him well, but I’m just not sure I can ever convince him to change his habits.
