Prime-T Review

Remember that Simpsons where the Mafia and Yakuza end up fighting on the family’s front lawn? Remember Homer is watching a quiet little guy who hasn’t done anything because he’s sure he’s sure something cool will happen?

Always the quiet ones

That’s a little how I feel about Prime T by RSP Nutrition. In a market of bold claims and loud packaging, there’s something refreshing about a no frills brand that doesn’t feel the need to jump off the shelf at you.

Of course it could just be the company are a bit cheap and have cut as many corners on marketing as they have the formula. There’s only one way to find out.

RSP Prime-T

Prime-T promises you;

  • Support for free and serum testosterone
  • Greater lean muscle
  • Stronger libido
  • Better T and estrogen balance
  • Sustained prostate health

In a further show of confidence, we got all the individual dosages right there on the label in plain sight. No proprietary blends, which is great.

So as far as we’re concerned Prime-T stands for Prime Target for reviewin’. Let’s check it out

How Does It Work?

At a Glance

  • Vitamin D3 & D-Aspartic Acid to boost T
  • DIM to limit estrogen
  • Fenugreek to balance blood sugars
  • B vitamins to help with energy
  • Maca to boost libido
  • Boron to improve hormonal balance

We’ll breakdown everything you need to know after the scores

The Scores

The Scores

Active amounts of Vitamin D3,  D-Aspartic Acid, boron and fenugreek give Prime-T in a stronger base than a lot of boosters and ensure it will be of some use to most. Zinc though is disappointingly light and though the B vitamins help with energy and overall health, they don’t do much for T.

The anti-estrogen profile could also be stronger and just one serving a day means for all Prime-T’s plus points it won’t be as effective as it might have been.


Around $30 a month is no small ask of your wallet, but in reality it’s about average for this kind of booster. Given then that though it’s not perfect, Prime-T is an above average product, it’s probably pretty good value. So if the really top quality options are a little out your price range for the moment, then this is potentially a pretty good stop gap.


Trust is not an issue with Prime-T really. It’s from a well-established company, so isn’t any kind of money making scam. It’s produced in the U.S so has to comply with GMP regulations and there are no proprietary blends keeping us out the loop on ingredients. There are a few issues however.

One or two components aren’t maybe as strong as they’re presented and suggesting that just one serving a day is optimum is pushing it.


Prime -T is generally very strongly reviewed on the retail sites where it’s available. Great as that is, we always say user feedback of this sort is usually short of details and usefulness. We’re not saying all these positive experiences are fake, just that, without the depth of dedicated individual testimonials it’s difficult to make a properly informed choice.


RSP Nutrition was founded in 2009 in Miami Florida by student athletes to help support a variety of fitness goals naturally.

Since then they have gone on to produce many supplements covering nearly all aspects of a healthy lifestyle. Their products are popular and we couldn’t find any major scandals. A bit more company background would be nice but that’s a small thing.
