Unfortunately, not much is known about RSP Prime T's manufacturer, besides the name, which can be a bit worrisome for the user.

Also, although there are active amounts of Vitamin D-3 for testosterone absorption, D-Aspartic Acid, boron and fenugreek which gives this product a solid base, the levels of zinc aren't high enough to make a difference. The vitamins and solid base provide a healthy formula for men's well-being, however there aren't many T boosters included.
