You absolutely cannot go wrong buying this product if you have ever thought of using Anabeta, C20, or Triazole. The 3 main compounds from those products are all contained in MAN PR-XT at non-prop doses and at 1/3 of the price of purchasing all 3. I have used all 3 individually myself and can say that MAN PR-XT delivered on each compound's benefits. I have run 1 bottle and am now starting my second and still saving money from not buying all 3 of the other products. No brainer in my books guys.
