Boost testosterone levels with D Aspartic Acid (DAA)

D Aspartic Acid is an essential amino acid that’s a key ingredient in Bulk Nutrients' Test Max and is used in various testosterone boosting anti-estrogen supplements.

D Aspartic Acid has been shown to improve hormone function with significant effects. In one trial using daily doses of 3.12g, 87% of participants experienced increased hormone levels, with an average increase of LH levels by 33% and testosterone by 42% (Topo 2009).

D Aspartic Acid can be an effective supplement for building muscle in males. Muscle and fat growth is directly linked to testosterone levels with higher testosterone levels improving the ability to build muscle.

D Aspartic Acid works best when paired with Diindolylmethane to ensure no negative impacts from increased estrogen.

    D Aspartic Acid

    So much nicer than other brands I've tried. Dissolves really well and there's much less tangy powderyness than other brands. Definitely will buy again

    Since having this product I’ve had more energy helping me push through my workouts, would recommend to anyone looking to push that bit further into their gym sessions

    Good testosterone boost

    Seemed to notice results after about 7 days. Best to cycle ( 10 days on 10 off worked quite well) Slight increase in strength in the gym was also noticed. A good product worth trying.

    Was sceptical, no longer

    Id been reading a bit about DAA including research done for some time, but I was still sceptical. For $10, eventually gave it a go.....why not...but wow! Most noticeable and sudden change from any supp I've taken. Has helped toning considerably (lower fat and more muscle def). Im 42yo male with good test levels anyhow - so sure enough, I get a fair bit of acne when using DAA (which I now cycle just 5d on (4d off) - best results for me that way), but a Benzoyl Peroxide over-the-counter wash has killed the acne now. No other side-effects. (DAA probably not worth it for anyone under 30 though). A winner for me.

    D Aspartic Acid has arrived in time apart from a prompt delivery like twenty four hours from Tasmania to Sydney. I am seventy four years old and I and was in the last year starting to feel physically vulnerable but after taking D Aspartic Acid for at least and month in my case my physical confidence has returned. Oh by the way this is also helping my wife with her energy levels as well as she only takes about a quarter of what I take.
