Blood work - timing etc.

[Burkmere]

I know I read it somewhere but if I get blood work done in the morning (I'm doing androgel on the shoulders and upper arms) should I take the gel that morning or just be careful that they are taking blood lower down on my arm? Afternoon? What are the general rules again? Thanks.

The general rule with creams/gels is to get tested a couple of hours after you apply the gel in the morning. This way one can see how much testosterone one's body is absorbing. This is going to show your peak testosterone level.
