Why should I have my blood test before applying the gel?

Having your blood test before applying testosterone gel allows your doctor to measure the "trough" levels, which are your body’s baseline testosterone levels just before the next dose. This gives a more accurate assessment of whether your dosage is correct and whether adjustments are needed. If you apply the gel right before the test, your levels could spike temporarily, leading to misleading results.
