Novadex, or Novedex, is a testosterone booster from Gaspari Nutrition. The supplement no longer appears on the official website, but it is still available from third-party vitamin companies. Novadex is an aromatase inhibitor. This simply means it inhibits estrogen so testosterone levels rise. Unlike so many other testosterone boosters, Gaspari Nutrition chooses ingredients with at least some clinical backing, though only in animal testing.

Products can typically be ordered directly from Gaspari Nutrition, but that is not the case with Novadex. Bodybuilders need to order this product from another supplement company. We found no testimonials for Novadex. Before ordering, consumers need to ask about the expiration date on the supplement. If Gaspari Nutrition no longer lists the product, other websites could be selling out of old stock.

List of Ingredients

6, 17 Keto-Etiocholeva-3-Ol Tetrahydropyranol; 3, 17 Keto-Etiochol-Triene and 3′, 5 7-Trihydroxy-4′-Methoxyflavanone.

Product Features

The ingredient list for Novadex is more complicated than it needs to be. 6, 17 Keto-Etiocholeva-3-Ol Tetrahydropyranol is 3-OHAT. This ingredient is in the same family as 6-OXO, a common aromatase inhibitor. While we could find no clinical studies referenced to supporting anti-estrogen claims, Gaspari Nutrition filed a patent application for the ingredient.

3, 17 Keto-Etiochol-Triene is recognized as ATD in the bodybuilding circle. There are clinical studies for ATD, but all involve animal studies. No human studies have been completed to confirm the same results in the human body. Despite the lack of human testing, bodybuilders trust ATD and Gaspari Nutrition has filed a patent application for this ingredient as well.

3′, 5 7-Trihydroxy-4′-Methoxyflavanone is a flavonoid known as Hesperidin. Hesperidin has antioxidant and anti-inflammatory benefits, but we are not sure why it is included in a testosterone booster or estrogen blocker. It could be linked to the increase in free radicals during bodybuilding. Antioxidants fight free radicals.

The Novadex formula will not help a dieter eat less, move more or lose weight. The formula is dedicated to boosting testosterone or blocking estrogen. If the formula works as claimed, a female dieter taking this supplement could suffer from amenorrhea and increased body hair, common symptoms of too much testosterone.

Bodybuilders take supplements for the opposite reason dieters take supplements. Bodybuilders want to gain and dieters want to lose. Novadex aims to increase testosterone and decrease estrogen, creating the optimal environment for muscle building. There is some evidence the supplement will achieve that goal, but Gaspari Nutrition seems to have discontinued the supplement.

    Hi, Leander. Ordinarily diet products are taken twice daily. Be sure to go over the specific directions of the product, and also consult your doctor.
