Ingredients in test supplements are the key elements in reviving T levels.

Pay attention to the components formulated within the tablets, as these are the most important details to determine if the supplement is effective or not.

Let's check out the ingredients you can find in RSP Prime T:

  • Vitamin D (as cholecalciferol) - Vitamin D can help boost your T levels, especially if you're Vitamin D deficient. Four tablets contain 3000IU, which is more than enough supplementation for your body.
  • Vitamin B3 (as niacinamide) - Vitamin B3 is an efficient fat burner. This vitamin in your dietary supplement assures you that it can help you eliminate unwanted body fat.
  • Folate (as folic acid) - This mineral effectively helps muscle recovery. Hence, if you're a gym rat, you'll be able to bounce back easily, even with intense exercise routines.
  • Vitamin B12 (as cyanocobalamin) - Vitamin B12 is effective in helping users grow muscles, especially if you're deficient in it.
  • Zinc (as zinc citrate) - Deficiency in Zinc also results in a decrease in T levels. This mineral in the supplement's formula can efficiently rev up your T in this case. However, Zinc can interfere with certain medications. Consult your doctor before taking these tablets.
  • D-Aspartic Acid - D-aspartic acid helps in boosting test levels temporarily. It helps in releasing luteinizing and follicle-stimulating hormones. You can get 3200 mg D-aspartic acid supplementation in this supplement.
  • Fenugreek Extract - Fenugreek aids in supporting male reproductive health and D-aspartic acid. It can help in maintaining normal test levels in men.

  • Maca Extract (root) - Maca extract is another key ingredient in these tablets. It helps increase sex drive and libido among its users.
  • 3,3' - Diindolylmethane (DIM) - DIM is commonly found in cruciferous vegetables like broccoli. It's believed to help increase natural testosterone production as well. However, it's also shown to increase estrogen activity, making this a controversial component.
  • Safed Musli Extract (chlorophytum borivilianum) (root) - This Indian herb serves as a natural aphrodisiac. It's essential in improving serum testosterone levels and promoting better functioning of testicles.
  • Boron Citrate (supplying 5% boron) - This ingredient is essential in balancing testosterone and estrogen levels in the body.
  • BioPerine - Although this component is not as helpful in increasing test levels directly, it's still important, given that it helps with the bioavailability of other ingredients.

Other ingredients are:

  • Dicalcium phosphate
  • Microcrystalline cellulose
  • Croscarmellose sodium
  • Stearic acid
  • Magnesium stearate
  • Silicon dioxide
  • Titanium dioxide

What Are the Side Effects of Prime T Test Booster?

Despite the claimed benefits of RSP Prime T, there are still some drawbacks you must consider before purchasing.

One major side effect you can expect from using these supplements is an imbalance in estrogen levels.

Aren't these supplements intended to level estrogen in the body to boost test production?

Certainly, it's what RSP Prime T claims. However, let's not forget that it contains a high dose of diindolylmethane (DIM).

Studies revealed that DIM increased estrogen activity in some men(1).

There's no substantial scientific evidence around its effects on hormones. However, observing the body's reaction after taking the tablets for several days is best.

The following side effects of increased estrogen levels are:

  • Enlarged breasts
  • Weak libido
  • Belly fat

How to Take Prime T?

As it says on the package and their website, you should take the tablets 30 to 60 minutes to an hour before bedtime on an empty stomach.

Follow the instructions to make sure you get the most out of the test supplement.

What Is the Recommended Dosage for Prime T Supplementation?

As for the recommended dosage, you must take four tablets every day.

Since DIM is part of the formula, it would be best if you took exactly the suggested amount. Taking too much may result in an estrogen imbalance.

What Are the Best Alternatives to Prime T Testosterone Supplement?

If you're looking for other alternatives to RSP Prime T, the best brand we can recommend is Testoprime.

Similarly, it promotes overall wellness in men. It's made with ingredients that have been shown to increase the amount of free testosterone in the body by a lot.

With this, you can grow your muscles effectively and increase your physical energy, strength, and stamina.

It also benefits cognitive functioning in men by improving mood and reducing stress.

Besides that, TestoPrime improves sexual performance and libido and enhances sperm quality.

A major takeaway from this brand compared to Prime T is that it doesn't contain DIM.
