Optimise Performance Through Improved Hormone Production

NZProtein's Test Booster contains an advanced blend of natural ingredients reported to support and boost testosterone levels and libido, optimising performance via improved hormone production. Optimal hormone production supports faster recovery, increased strength, and muscle development for bodybuilders, strength and power athletes.

Testosterone levels decline after our twenties and may decline at varying rates depending on factors including genetics, diet, stress, activity and so on. Supplementation with a test booster product may help to maximise power and performance and achieve greater results.

difficult to say whether this has had any influence

Brutally honest review - It may just be me, as everyone's bodies are different, but for me personally, I didn't notice any difference in testosterone at all and ended up chucking the bottle half way through. Really disappointed in it and wasted money on it. I wouldn't get this product again, personally.

I like NZPROTEIN's whey protein powders, whey protein isolate powders and the shaker bottles, but as for the testosterone booster product, I won't bother with testosterone products ever again, as it did nothing for me.

From what I can gather from male fitness model Weston Boucher on YouTube, one of the only real ways to boost testosterone (with actual tried and true tests and results) is with Testosterone Replacement Therapy (TRT), but that requires physical injections of the stuff, and honestly, I wouldn't be comfortable with 1) needles, 2) dosages, 3) the potential side effects, 4) the fact that it's pretty unnatural to have to require jabs of testosterone just to feel normal again, and 5) the trustworthiness of the ingredients in the jab. So for me personally, for all the above reasons, I just give up on finding a testosterone boosting product, because it's either unnatural, or it doesn't actually work. Fitness YouTubers seem to concur that testosterone booster supplements don't work when it comes to the solid evidence of testing levels of testosterone in the body and that it's a waste of money. I won't be getting this again, but it may just be me, so do your own research and if it works for you, that's awesome.

Definitely a staple for me. Tried some other boosters from other places but as soon as I hit this again I could definitely feel the difference. Keep up the great work NZ Protein!
