Testogen Review (TestoGen Before and After Results)

Testogen has massively improved their formula recently. I like the new formula a lot more, especially the addition of Magnesium and the updated Zinc levels.

So, being me, I decided to put it to the test.

Below you can find my personal results from using Testogen PLUS a full scientific analysis – where I break down each ingredient and look to see if there is proof backing up its proficiency as a test booster.


Here’s a quick summary of my review

  • The new ingredients formula is much more effective than it was
  • It contains all my most important ingredients that have been proven to boost testosterone levels in multiple studies (DAA, Magnesium, Zinc, Vitamin D).
  • The ingredients and dosage levels are all perfectly safe – no risk of side effects.
  • This is my best overall test booster but if you are over 50 and looking specifically to increase libido and daily energy levels then I still prefer Prime Male.

Conclusion: I really like the new Testogen formula, this is my top test booster right now. If you are looking for a supplement to help you gain muscle, burn fat and recover between workouts – Testogen is a great choice.

Review Criteria

When reviewing any testosterone booster, the ingredients formula is always the first place I look.

I am looking for ingredients that:

  1. Are backed up by multiple scientific studies that prove their effectiveness in boosting testosterone levels.
  2. Occur in the right dosage levels to be both safe and effective
  3. Are completely natural and non-toxic.

Read on for my full Testogen testosterone booster review.

Who is Testogen For?

Testogen has certainly been targeted at the body building and muscle building market.  For those who want to work out, bulk up and make gains. The idea is that by increasing your testosterone levels you will achieve the following benefits:

  • You will achieve more muscle growth
  • You will get more energy to push yourself harder at the gym
  • You will increase recovery time between workouts
  • You will metabolize quicker and shred body fat.

All of these things are certainly side effects of higher testosterone levels. However, this begs the question. Can TestoGen actually increase your testosterone levels?

To answer this question we will get into the science below and find out if there is real evidence to back up all of these claims.

TestoGen Ingredients

The two biggest changes in the new formula are:

  1. The addition of Magnesium which is crucial in maintaining healthy testosterone levels.
  2. Less Zinc – the previous dosage (72mg) was a bit high for my liking and presented some potential safety concerns. The new dosage (10mg) is much better – it is within the daily recommended dosage so their are no safety concerns while still being enough to have a significant impact on testosterone levels.

They have also added a few more ingredients and changed some of the dosage levels – and I am very happy with the changes they have made. You can see all the new ingredients in my Testogen review below.


D-Aspartic Acid

Right off the bat, I can tell you that this is a very potent level of D-aspartic acid. In-fact it is the highest amount out of any booster on the market right now. I like to see this as DAA is definitely the most impactful ingredient to look for in a test booster. I can tell from this high level of DAA that this product is aimed more at the muscle building market than at guys with low t. This is because DAA is very useful for muscle growth and helps the body to use testosterone better.

In one study an experiment was performed on 23 men enrolled in an infertility program. 3.2g of D-aspartate was administered to them daily for 12 days with blood samples being collected both before and after each treatment. The results were significant increases of testosterone in 20 out of 23 of the subjects, these levels did not decline until about 3 days after the treatment ended.

In another study, a supplement containing 1.6g of d-aspartic acid and 0.4g of L-aspartic acid was administered to men between the ages of 25 and 40. The participants took the supplement daily for 20 days with food at lunch. Eight out of the ten men had a significant increase in testosterone levels.

D-Aspartic Acid regulates amino acids that are responsible for hormone production, naming luteinizing hormone (LH).

The hypothalamus produces luteinizing hormones in the brain. Once these hormones enter the system, they travel down into the testes. This is what facilitates sperm production.

Releasing sperm helps to regulate the clockwork system that is our body. The more sperm you produce and release, the more testosterone the testes will release into the system.


One of the underlying issues in testosterone production is that fact that our body cannot access most of the testosterone in our system. When testosterone is released, 98% of it gets latched onto by a naturally occurring protein called sex-binding human globulin (SBHG).

SHBG renders the testosterone it comes into contact with useless. As a result, only 2% of the testosterone in our bodies is considered free testosterone. That means all the hair, muscle mass, and sex drive that men can muster is a result of that 2%. After the age of 40, that number becomes even smaller.

However, studies have shown that magnesium hurts SHBG. When this chemical comes into contact with SHBG, it strips the protein off of the testosterone that it is choking the life out of. In turn, that once useless testosterone becomes free testosterone, and our bodies can reap the benefits of the hormone.

Vitamin D

Males with a depleted level of Vitamin D are susceptible to the growth of estrogen, the hormone responsible for giving women feminine characteristics. As estrogen levels increase in men, the body stores fat differently, shifting all excess weight to the gut area to make room for an impending fetus. With total estrogen elevated, men are more prone to depression, heightened risk of cardiovascular disease, and ED.

What makes Vitamin D so critical to warding off estrogen is that the cells that lie inside testosterone’s synthesizing glands contain Vitamin D receptors. When the two work together, they kill an enzyme in the body called aromatase. This enzyme is the precursor to estrogen production.


While this might not be the most well-known nutrient, it is important in testosterone production. The reason being is that just 10 mg of boron may increase the output of free testosterone by 28%. Coinciding with these results, the studies further found that boron also helps lower the levels of estrogen within the body as well.

Vitamin K1

Working out and building muscle is a great way to increase testosterone. However, dead-lifting and squatting challenging weights can cause wear and tear on the joints, bones, and muscle. Vitamin K1 is essential in rejuvenating those strained ligaments.

Furthermore, Vitamin K1 compliments and strengthens Vitamin D when they interact with your system. Vitamin K1 speeds up bone metabolism, which is where growing bones shed off the debris of dead cells, and grow stronger bones in its place. This is especially important for those who have increased reps in the weight room following an increase of testosterone within their system.

Nettle Leaf Extract

Much like magnesium, the oils within the leaves, stems, and roots of this plant have a negative effect on SHBG. Much like SHBG binds onto testosterone, compounds within nettle leaf extract called isolectins bind onto SHBG. When this happens, SHBG is no longer free to latch itself onto freshly produced testosterone, rendering the hormone free.

10% of free testosterone is turned into a male hormone named dihydrotestosterone. While this hormone is good for the body, as more testosterone enters the system, more of it is converted into dihydrotestosterone. As they say, there can be too much of a good thing.

Too much dihydrotestosterone may result in less hair and the growth of tissue within the prostate. Studies have shown that nettle root extract is effective in prohibiting the growth of the enzyme, reductase, the precursor to dihydrotestosterone. Not only that, but the extract also reduced inflammations of prostate tissues as well. Therefore, nettle root extract is effective in ensuring that free testosterone doesn’t covert too much of its proteins into dihydrotestosterone.


Fenugreek Extract

Like many other ingredients in this supplement, fenugreek extract boosts libido and testosterone levels. However, what makes this extract so unique is the influence it has on insulin release.

Fenugreek Extract increases the release of insulin into the system, which is important for those who are looking to recover their muscles after strenuous exercise. The reason why it is so effective is that compounds within the herb bypass all body parts and are absorbed directly into the liver.

This allows for the system to regulate insulin release at a quicker pace, alleviating soreness and boosting recovery time.

Red Ginseng

This herb is extremely useful in battling ED. One of the leading causes of ED is due to hardened arteries. Choosing to eat food with artificial ingredients, preservatives, and other additives adds up over time. As our bodies become unable to break down these refined sugars and foreign substances, they clog up the arteries and with time, harden.

When this happens, blood is not free to flow throughout the system. That means that the pathways to the heart, brain, and testicles are all blocked. When this happens, bouts of ED begin and in time become chronic.

One of the strongest cleaning agents for the arteries is a gas called nitric oxide. Nitric oxide is responsible for clearing the pathways in the arteries of buildup, debris, and dead cells. Studies have proven that red ginseng has a significant impact on increasing nitric oxide production.

Vitamin B6

There’s no doubt that we slow down as we get older. As oxygenated blood has trouble pumping throughout the body, lack of oxygen to the brain can have many adverse effects. These effects include lack of sleep, irritability, and depression.

When testosterone production is halted, other hormones take over. One of these is cortisol. Cortisol is our stress hormone. It’s the leading cause of many disorders, including ED.

As stress becomes chronic, heightened cortisol levels become commonplace. The only way to halt the production of this hormone is to create other hormones and neurotransmitters that fix the problems excess cortisol causes. Studies have shown that Vitamin B6 helps facilitate the production of serotonin. This is a neurotransmitter that helps give the brain signals of happiness. Naturally, this causes cortisol levels to decline.


It’s undeniable that immune systems are easier to compromise when we age. That’s what zinc such a great supplement during the cold season. Not only does zinc have immune-boosting properties, but it can also bump up the T levels.

A study with athletes found that taking 3 mg of zinc each day for a month saw a significant increase in testosterone levels compared to those who received the placebo (study).


Much like Vitamin K1 and Vitamin D compliment one another, Bioperine compliments all the active ingredients in this supplement. Derived from black pepper, this chemical compound accelerates the bioavailability of many naturally occurring chemicals. That makes it easier for your body to absorb all the other nutrients.

Thoughts on Ingredients Formula:

Testogen’s new formula is far superior to the old one. All the ingredients are backed up by scientific studies and they occur in safe and effective dosages. They have hit the mark with the new formula and taken their place as one of the top products currently on the market.

Testogen Dosage – How to Take it

Essentially you take four tablets a day as often as you want. I highly recommend cycling any testosterone booster with three weeks on, one week off. Then take a whole month off every six months or so. This is so your body doesn’t get used to it and you don’t get diminishing returns over time.

TestoGen Side Effects

All the ingredients are natural and safe, the only danger here is the high levels of Zinc, this can cause headaches and nausea. If you notice either of these symptoms, then please stop taking this supplement immediately. Better yet, get your doctor’s recommendations on how much zinc you should be taking before taking this supplement. I could not find any reports of Testogen side effects online so I think you are probably pretty safe.

While the active ingredients in this supplement are naturally occurring, they are still comprised of chemicals. That is why if you take TestoGen along with other medications, there may be some adverse reactions.

TestoGen Customer Before and After Results

Before purchasing any supplement for the first time, it’s good to get a feel for how others that used the product found it. Suffice to say, using TestoGen seems to be a positive experience for anyone who has used the supplement.

One of the most resounding results for those who have used it is noticeably more muscle. This is true of this who were in good shape and for those who carried excess weight. Users noticed a huge improvement when it comes to energy levels in the weight room.

TestoGen seems to work across the board for those at any age. While it is most popular with people in the late 40’s to mid-50’s who use the supplement to improve their mood and libido, results have been recorded for younger people who have also noted a positive change in outlook on top of their increased muscle mass.

Does TestoGen Really Work?

The updated ingredients formula is fantastic. It’s not quite as complete as something like Prime Male – but that is because Testogen is mostly aimed at the fitness and muscle building markets while Prime Male is an overall vitality and anti-aging supplement.

Testogen actually has higher levels of D-aspartic acid than anything else I have seen so will work great to assist you in your workouts. So if you are looking to increase strength, bulk up, burn fat, increase recovery time between workouts and boost energy at the gym then this is a great choice.

While some potential side effects may be a cause for concern, TestoGen’s positives far outweigh their negatives. One of the most striking results from reviews is the amount of muscle mass those who use the supplement have put on.

TestoGen helps a man feel like a man again and does so without the use of man-made chemicals. These reasons alone are enough to get our endorsement for TestoGen as a reliable testosterone-boosting supplement.
