customer reviews of Muscletech Test HD they’re actually relatively positive,
overall. There are definitely a few fake ones in amongst their overall rating
of 4.2*, but overall they’re pretty decent. There’s a couple of decent
ingredients in here, that should have some effect and they do get the vitamins
right, which in many cases will show men positive results. This is typically a
sure fire way to guarantee a test booster gets reasonable customer reviews. A few
of the negative reviews did reference Muscletech Test HD side effects, most
commonly lethargy, which is unusual for a test booster and there aren’t really any
ingredients in here that we’d expect to cause this.
Calcium – Whilst calcium does have some benefits in the production of
testosterone, supplementing for just 5% of your recommended daily intake isn’t
really going to make a great deal of difference, so this is a bit of a pointless
ingredient to have in the product.
Zinc (As Zinc Gluconate) – Zinc is essential for healthy testosterone production and deficient men do typically have reduced rates, supplementing has been shown to cure low testosterone in zinc deficient men. As the mineral is so important, we do like to see it in test boosters. There is only 50% of the RDI in here, whereas most better test booster do include 100%.
Sodium – Not really necessary, very few men are deficient, supplementing for it is redundant.
Tribulus Extract – Tribulus at 250mg is a decent inclusion, it’s been used for quite some time in test boosters, and is shown to improve athletic performance. 
Shilajit Extract – Shilajit is middling as a test booster, and beyond that in Muscletech Test HD it’s underdosed, the only placebo-controlled trial was done using 250mg and here we only have 100mg. 
Boron Citrate – as mentioned in the introduction, boron is underdosed, 5mg whereas 10 is the ideal. 5mg will still have some effect, but not as well as a higher amount.
Broccoli Powder – This is of no use for testosterone boosting and is simply a gimmick that muscletech keep putting in their products.
Stinging Nettle Extract – This is OK, but stinging nettle extract is one of the less effective ingredients found in test supplements.
Safed Musli Extract – This is actually quite unusual as ingredients go, and it does seem to have some efficacy, but the trials that back it required dosages of 1000mg  a day not the 50mg dose in Muscletech HD.
Test HD is a poor product, there’s a couple of testosterone boosting ingredients
in here, but nothing that’s going to do a great deal. The worst thing is that
it’s actually at quite a high price point for what it is, doing very little to
boost test levels. We don’t recommend this product, you’d be far better off getting
something containing ginseng, DAA’s or Ashwagandha as these all have more
potent effects than the ingredients in Muscletech HD.
Muscletech HD is their worst testosterone booster, you’d be better off with MuscleTech Alpha, or Elite instead. Although none of these made it onto our best testosterone boosters list.
