Halotropin Review

It’ll shock to no-one how much focus testosterone boosters put on helping raise your T. But in truth, that’s only half the battle.

You should also have an eye on lowering your levels of the female hormone, estrogen. Yup you’ve got that too, and it starts to creep up as we age, damaging T production.

This is why we’re keen to check out ProSupps Halotropin, which bills itself as a ‘T booster & Estrogen Blocker’.


That’s exactly what we want to hear. They don’t call it a hormonal balance for nothing y’know. So we know the marketing department have done their job at least, but what about the lab?

The best way to figure out if a booster is worth your time and money is to first look in detail at the ingredients and their dosages. In Halotropin’s case that’s going to be tough, because infuriatingly the main body of the formula is wrapped in a 1,100mg proprietary blend.

For those of you who don’t know, proprietary blends are an FDA loophole which lets companies avoid telling you exactly how much of each ingredient you’re getting. This means a) no guarantee of doses high enough to work and b) no way to rule out side effects.

Let’s check it out anyway and see if Halotropin has the (literal) secret to success.

How Does It Work?

At a Glance

  • ZMA combination to support T.
  • White Button Mushroom & DIM to block estrogen
  • Fenugreek to balance blood sugars
  • Tribulus to supposedly raise T
  • Rhodiola & Ashwagandha to lift energy and focus

We’ll check out all this in more detail after the scores

The Scores

The Scores

Patchy doesn’t begin to cover it. There are strong choices like fenugreek, magnesium, mucuna pruriens and nettle, which will all help T, but these are let down and mysteriously mixed up with some duds.

The estrogen blocking side isn’t nearly as convincing as it could have been, and the formula is fleshed with a few pointless libido boosters.

There are questions all round here. With the good, it’s how much are we getting? With the under researched, it’s are you sure? And with the bad, like Tribulus, it’s what are you trying to pull?


Although Halotropin is far from all bad, north of 40 bucks a month is a lot for most of us to take out the budget. We’re missing enough answers about – and ingredients from – this formula to say we don’t think it’s worth it.

If you’ve got the cash, by all means give it a try but there are other brands around the same price range which are more impressive. Our advice is hold out for them.


Halotropin is made in the U.S, which means it has to meet certain manufacturing standards before reaching you.

However, it still falls short in our eyes as far as standards of consumer trust. There’s no excuse for not letting you guys or us in on what doses are used. It suggests the balance of good and bad ingredients in this really mixed bag of a booster may not be the greatest.

We also wish they’d been a little more careful with that zinc and cut out any risk.


In ideal world ProSupps would have a really detailed breakdown of user experiences in their own testimonial section, but the world is pretty far from ideal. There isn’t one.

As far as customer feedback on retail sites, Halotropin reviews generally do pretty well. But there are enough ‘didn’t work for me’ and ‘did nothing’ reviews out there to leave us wishing for a bit more depth so you knew who to believe before opening your wallet.


ProSupps are a supplement company founded in Texas and operating since 2004. In that time they have achieved great success, worldwide reach and have a number of products to their name, including T boosters, fat burners and pre-workouts.

They are by no means a shady company, but the occasional use of synthetic compounds and regular reliance on proprietary blends, we could do without.
