Question on T Cream Dosage

StepbyStep

Active Member
when using creams, do not apply to the inner arm of the side which will have blood drawn. Residual testosterone in the skin in the puncture site will give a false high reading of testosterone. I know this from experience. I don't apply any cream to the inner arm being used for the blood draw for 2 days prior to testing.
Have you tested your trough on tropicals?
