Cellucor P6 Ultimate Reviews

Cellucor P6 Ultimate Ingredients

DIM (Diindolylmethane) 100mg: Some studies suggest that DIM may support healthy estrogen metabolism, which could indirectly impact testosterone levels. However, more research is needed to establish a direct link. There are also some issues with taking DIM over long periods of time, with some studies suggesting that this can in fact lower testosterone levels. [1]

Longfolia (Eurycoma longifolia) 100mg: Also known as Tongkat Ali, Longfolia has been traditionally used to enhance male fertility and libido. While some animal studies have shown a positive effect on testosterone levels, human studies are limited.  However, even if we do assume it works, 100mg is on the lower dosing end, which would mean it would take about 12 weeks to have any effect on testosterone levels according to the existing studes., which isn't ideal in a supplement you can only take for a few months without feeling ill if the customer complaints (and what we know about DIM) are to be taken into consideration. [2]
 
Ancient Peat 150mg: Ancient peat contains various minerals and trace elements. While it may support overall health, there is insufficient evidence to suggest a direct impact on testosterone levels. [3]

Velvet Bean (Mucuna pruriens) 416mg: Velvet bean contains L-dopa, a precursor to dopamine, which plays a role in testosterone production. Some studies have suggested a positive effect on testosterone levels, but more research is needed to confirm these findings. Almost all studies currently are on animals and there isn't really anything to substantiate that this will work in humans. [4]

Shilajit 500mg: Shilajit is a mineral-rich substance that is believed to have various health benefits. While some studies have shown a positive impact on testosterone levels, more research is needed to establish its effectiveness. This is probably best for mental acuity and potentially has some mood boosting effects, but it isn't as effective as we'd expect something like Ashwagandha to be for most people. And that would take up a similar amount of capsule space. [5]

L-Lysine HCl and L-Arginine 1200mg: These amino acids are involved in protein synthesis and have a role in hormone production. However, their direct impact on testosterone levels is not well-established, and to be quite frank almost none existant, there is some evidence to suggest that they can help with muscle growth however. [6]

Vitamin D 125mch: Vitamin D deficiency has been linked to low testosterone levels. Supplementing with vitamin D may help raise testosterone levels in individuals with deficiencies, but it may not have the same effect in those with normal levels, it has however been shown to improve athletic performance when supplementing beyond normal levels, which considering a lot of men buy testosterone boosters for muscle growth, this makes it a good inclusion. [7]

Vitamin B6 1mg: Vitamin B6 is involved in testosterone synthesis. However, there is limited evidence to suggest that supplementing with vitamin B6 alone can significantly raise testosterone levels unless a person is deficient in multiple b vitamins which is relatively rare. It's a small inclusion in the capsule however and can improve energy levels reducing the symptoms of low test, but again this is a standard ingredient in most, much better testosterone boosters. [8]

Cellucor misses zinc, which is actually the most effective testosterone vitamin when we account for the fact that even a minor deficiency can tank testosterone levels. And it's particularly prevelant in the USA with some studies suggesting almost 30% of American men over 50 could have a sub clinical deficiency. [9]
