Measuring absorption rates?

[Moyer]

Anyone got good ideas on cheaply measuring the absorption rates of a given transdermal gel?

I'm thinking bulk caffeine anhydrous powder is the best option?

Differentiating 100 vs 150mg might not be too noticeable though. What are you trying to figure out?

The absorption rate. I got a really cheap home brew and I don't want to waste expensive or scarce powders trying to see if it works.

Some people get a metallic taste in their mouth when they apply 1-Testosterone, unfortunately I'm not one of them.

I've considered DHEA, but I don't think it would be noticeable enough to tell.

I'll probably end up tossing it and ordering the new penetrate, but it seems like there must be some easy way to test it.

mix some arsenic in it, put some gloves on, and rub it on someone you dont like... then standby to see how long they last... shouldnt cost you a dime lol unless you don't own rubber gloves and arsenic haha
