Poxet 90 mg contains dapoxetine, a short-acting SSRI used to delay *****. It is not a testosterone booster and is not intended to treat low testosterone. Sunrise Remedies +1 Testosterone levels: Available human evidence suggests dapoxetine does not significantly change testosterone levels, although the evidence is limited. Sex drive: It may cause ***** side effects in some people, so changes in libido do not necessarily mean testosterone has dropped.

Do not use it without medical supervision; ask your doctor whether a lower dose is appropriate.
