Natural testosterone boosters have become a massively popular way to safely and effectively raise your male hormone.  But it’s a crowded market out there and it’s easy for some brands to fly under your radar.  This is the case with Prime Rut from supplement company Bold Buck.

Prime Rut

The imagery and branding is spot on.  If you’re worried about age related T loss the desire to regain the energy, strength and libido of a rutting young stag will certainly pull you in.  But visuals aren’t everything.  The only question that matters is, is this Buck worth a hard earned handful of yours?

The formula is proprietary blend which is always irritating.  This pointless gimmick FDA workaround means users aren’t trusted with any ingredient amounts, just their names and an overall volume.  In this case a pretty small 1560mg.

There are two problems with blends: first we can’t be sure everything has an active dose and second, we can’t rule out side effects.

Let’s take the stag by the antlers and see if Prime Rut can change our minds.

How Does It Work?

At a Glance

  • Horny Goat Weed & Maca to boost libido
  • Mucuna Pruriens promotes T & cuts stress
  • Yohimbe to help reduce fat
  • Ginseng for libido and blood flow
  • L-Arginine to raise nitric oxide levels.

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

The Scores

Prime Rut

There’s a couple of good ingredients in Prime Rut to be fair.  Mucuna Pruriens will help lower stress and stimulate T, while ginseng promotes androgens and healthy blood flow.

After that though there’s a handful of libido boosters, which are fine as extras but shouldn’t be the bulk of this kind of formula. 

Yohimbe is a bit of wildcard for this kind of supplement and actually brings with it the risk of side effects.  Prime Rut is missing a lot we look for in the best booster.  Could be a lot better.


At just over $20 Prime Rut may not be…deer (HI-OHHHHHHH! Thanks) but it isn’t that great either.  This price may not seem like a lot but when you’re paying it monthly, like a stag in mating season, it mounts up.

For what?>/em> In this case maybe slight increase in libido.  Not the best option on a budget.


Prime Rut is manufactured safely in the U.S and isn’t dangerous, but that doesn’t give it an A grade from us.

Not only are a lot of effective T boosting ingredients AWOL, we’re not let in on any doses of what is here and the formula does have the risk of side effects because of that.


No detailed testimonial section on the Bold Buck website so customer feedback on retail sites are our only guide.

These always lack the same detail and credibility of full testimonials, but in this case they’re pretty positive.  4 stars based on 90 reviews on Amazon.

Most report an increase in energy and libido as we said they might but that’s not the same as noticeably increased T.  Difficult to get a sense of quality without more in-depth info.


Bold Buck Nutrition are relative newcomers to the supplement industry.  They currently only have 3 supplements in their range, this T booster, a nootropic and a pre-workout.  We’re assured there are plenty more in the works though and what they already have is an impressive setup.

All products are American made and a good number of athletes already carry their banner.  Shame about the proprietary blends though.

How Do I Take It?

Users take 2 servings of 2 caps a day.

This will give you some short lived effects but to be honest the chances of just 2 servings keeping your hormone pumping for a full, busy day are pretty slim.

3, or preferably 4 servings, evenly spaced out over a number of hours is much more realistic.  This keeps active ingredients working consistently for as long as you need them.

Any Prime Rut Side Effects?

Yohimbe is one of the odder selections in Rut Prime, making a cameo from its usual home in fat burners.  It’s also the only ingredient which could cause problems.

In some cases Yohimbe can cause issues such as anxiety, hypertension and stomach upset.  We’d love to put your mind at rest and say you shouldn’t worry in this case, but thanks to the proprietary blend, we don’t have a dose and can’t say.

Where Can I Get Prime Rut?

Customers will find Prime Rut at Amazon.com where a month’s supply is on sale for $23.74

Ingredients – In Detail


Panax Genseng

Another rare highlight.  Promotes healthy sex drive, blood flow and androgens for T if dosed correctly.  Starting to see the problem with proprietary blends yet?


Horny Goat Weed

This won’t do much for actual T levels, but does show promise as a libido booster and may help in some cases of erectile dysfunction.




Much the same story.  Little to no effect on your testosterone but some studies report an increase in sexual arousal.



Mucuna Pruriens

A bit more like it.  Sometimes called velvet bean this ingredient stimulates production of the amino acid L-DOPA, which helps to stimulate T.  It can also cut cortisol, the stress hormone produced when we’re under pressure.  Lowering it not only stops testosterone being blocked but improves your mood.  Pity we have no idea how much is in here.


Poltpodium Vulgare

There are a lot of claims made about this herb.  Increased libido, raised T, even penis enlargement.  Unfortunately it all appears to be big talk rather than big cock.  Hardly any trials exist to back up these claims.


Yohimbe is more common to fat burners and it can definitely be effective.  It’s not completely without risk though as side effects are a possibility, especially when you’re not told the amount used.


Saw Palmetto

Saw Palmetto is particularly good for prostate health, something that becomes more important as we age.  So again not a direct help to T but not with it its use.  As long as the mystery amount is right.


Muria Puma

Another ingredient that may improve arousal but not much else,



This has been shown to help increase blood flow and raise energy but there’s a problem. L-Arginine is not well absorbed by the body when taken orally, so big amounts are needed.  Doubtful enough is here.


Anything Missing?

Um, just a few things.  For boosting T, vitamin D3, D-Aspartic Acid, magnesium, boron and zinc.

As far as controlling estrogen which rises as we age and hurts testosterone, they could have included natural things like vitamin B6 or luteolin.  None of any of this is included though.


Prime Rut might not cost the much, but if you’re looking for a supplement to raise your T, and have you feeling like a young buck again, then you should be hunting elsewhere.

Too many quality hormone promoting ingredients are missing.  Compared to the best boosters on the market this stag is looks more like Bambi.
