I'm now trying a simple 1mL a day with 0.5mL rubbed on each arm. If we're to believe the concentration of 85mg/mL then that should be 85mg a day, but let's say the actual absorbed amount is something low like 40mg. If 11kT is roughly equivalent to regular T then that's a pretty good amount. I'll try this until at at least Tuesday (4 days in total) and see what happens then because at that point there is a different, closely related hormone supplement I'm considering trying.

Note that from many other forum posts, it looks like others are often using 1.5mL daily. Maybe I should try that instead?

Also, here's something interesting. I also take 40mg of 6 keto p4 a day which costs $40/(360mg/40mg) = $4.44. 1.5mL of 11 keto T would be $70/(30/1.5) = $3.5. Maybe I could replace the 6 keto with this XI-KT stuff instead? It seems like it could actually be more effective if we assumed a worst case scenario of a 60mg T equivalence, roughly equivalent itself to 90mg of 6 keto p4.
