Testogen Vs Prime Male

Prime Male and Testogen are both popular products. So what’s the difference? Is one more effective than the other? Are they both safe? Find out with my in-depth comparison below.

Note: if you would prefer to read more in-depth information I have written a full Testogen review and Prime Male review.


Prime Male is a testosterone booster that is aimed primarily at older men over the age of 30. It is more of a vitality product giving all around increases in energy levels, libido, lean muscle mass and even focus. It is an all-around product that increases testosterone levels across the board.

Testogen is more aimed at the body building market and has much higher doses of d-aspartic acid and zinc than Prime Male. However, it does not contain all the ingredients I like to see in a testosterone booster. Specifically, it is missing magnesium while it also has lower doses of Vitamin D than Prime Male. You can check out the exact dosages in the images below.

Full Ingredients Comparison

There are really only four ingredients I look for in a natural testosterone booster to see if it will be effective. These are Magnesium, Vitamin D, Zinc and D-aspartic Acid. That’s because these ingredients the only once that have enough scientific proof backing them up, that we know for sure that they will help to increase testosterone levels.

Both products contain effective doses of Vitamin D, Zinc, and D-aspartic Acid. However, Testogen is missing Magnesium.

The reason Magnesium and Vitamin D are so important is that one of the most common causes of sub-par testosterone levels is vitamin and mineral deficiencies. In particular, Vitamin D and Magnesium have been clinically proven to impact the production and synthesis of testosterone by the body. What’s more, these are two of the most common deficiencies in men today. The main way we get magnesium is through leafy greens such as spinach which we don’t eat nearly as much of today as we used to a few hundred years ago. Vitamin D is absorbed through sunlight; with our modern-day office environments, a lot of men are not getting anywhere near as much of this vitamin as they should be.

D-Aspartic acid is probably the most effective ingredient you can get in a test booster and the fact that Testogen has higher dosages of it certainly helps to offset the lack of Magnesium, although it is not a full substitute for it. D-aspartic acid is very important for muscle gaining, so it makes sense that a product that is aimed at the bodybuilding market would have more of this ingredient.

Safety Concerns

One thing that I do worry about is the high levels of zinc in Testogen. If you have read my full research article on Zinc you will know that the clinical studies that have been done show that zinc toxicity can occur in doses of over 40 mg per day. Unfortunately, Testogen has 72 mg of zinc in each dose, compare this to Prime Males 30 mg and Prime Male is certainly the safer option. All other ingredients occur in safe dosages in both products, the levels of Zinc in Testogen is my only safety concern and the reason I would personally never use this product.


Testogen was looking pretty good until I uncovered the potentially harmful dosages of Zinc. For that reason, I really cannot recommend it to anyone, if you are going to take it anyway please be sure to consult with your doctor first. Prime Male is still my number one recommended overall testosterone booster for guys over thirty who are looking for energy, higher libido, more lean muscle mass and a bit less body fat. If you are only interested in hard muscle gains I would probably go with something like TestoFuel. It’s slightly more expensive than Testogen but definitely safer.
