I wanted to boost up my testosterone levels. any good results using testosterone products?

Yes but only if . . : Good results are achievable w/testosterone products such as androderm, androgel, axiron, fortesta, striant & testim, assuming they're clinically indicated, that you have no contraindication & that you're monitored closely. Testosterone is a controlled substance & has many potential side effects so don't consider this a do-it-yourself project but enlist your doctor. Don't use if you want fertility.

LOW T EVAL: Low T Evaluation and diagnosis of cause is critical. At 38 it is unusal and needs a through workup exam/labs/testiciular US/ and potentially a brain MRI. You will need regular Monitering of testosterone and PSA levels . Follow up with a through PCP and endocrine consult. Low T can cause symptoms of male menopause =ANDROPAUSE. Including anxiety/depression/insomnia/dry eyes . Ophtho consult too.
