Testogen, much like most of the other testosterone boosters I have reviewed on this site is made up of all natural Testogen reviewsingredients. The question is; will this test booster actually work in increasing your testosterone levels or is it just a scam like so many other products on the market? To answer this question, we need to really get in and analyze the ingredients formula. Read on for my full Testogen review.

Testogen Ingredients

D-Aspartic Acid – 2000 mg

Right off the bat, I can tell you that this is a very potent level of D-aspartic acid. 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 (as opposed to something like Prime Male). 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.

Tribulus Terrestris – 300 mg

Somehow this plant root received a lot of hype a few years back for having testosterone boosting properties however I could not find any scientific evidence to actually support this claim. This is more of a trophy ingredient to placate those who believe in the myths. This ingredient probably isn’t going to do anything for you, however on the plus side, it isn’t dangerous to take. This is basically a label filler.

Panax Ginseng – 250 mg

This ingredient has been proven to increase testosterone levels. In one study on sixty-six young men, there was evidence of strong correlations between Panax ginseng intake and increased free testosterone levels – studies.

Fenugreek – 200 mg

Fenugreek certainly seems to help a bit in raising testosterone levels although interestingly seems to be more important in helping to maintain testosterone levels. So it works well in conjunction with ingredients like D-aspartic acid which would raise testosterone levels, Fenugreek would then work to help the body maintain those higher t levels. In one study 60 healthy males aged between 25 and 52 took 600mg of Fenugreek extract over a six week period. At the end of the test period, all the subjects had t levels on the upper end of healthy limits. It was concluded by the researchers that Fenugreek helps to maintain healthy t levels. Fenugreek has been particularly effective in helping to improve lean muscle mass and help with weight loss. Read about the studies on Fenugreek.


Zinc – 72 mg

Behind DAA, Zinc is probably one of my favorite ingredients to see in a test booster. It has been clinically proven to boost testosterone levels. 32 male cyclists were given 30mg of zinc per day for 4 weeks. The serum testosterone levels of this group were significantly higher at the end of 4 weeks than the group who did not take Zinc supplements.

Here’s what I am not liking, the dosage level. I am assuming 72mg is supposed to be the daily dosage (there is no clear info on this). It seems very high, all of my research suggests that 30mg per day is about right and 72mg is not only excessive but can potentially be dangerous. Zinc overdosing is a very real thing and can cause headaches and nausea. Probably best to check with your doctor before taking such high levels of Zinc. It’s generally not recommended to take more than 40mg per day.

Vitamin B

To be precise Vitamin B6 (56mg), B2(20mg) and B5(12mg).  I am pretty meh about Vitamin B. That is to say there is no hard proof that Vitamin B increases the production of testosterone. However, there is proof to say that deficiencies in Vitamin B can lead to lower testosterone levels. So basically, if you have a Vitamin B deficiency this will help, if not then this won’t do anything. No harm in taking these dosage levels so you can feel completely fine about that.

Selenium – 45.2 mcg

So Selenium is generally considered to help increase testosterone levels, that why Brazil nuts have such a good rep, cos they are high in Selenium. One study I read did show a correlation between testosterone levels and selenium. Unfortunately, that study also measured Zinc levels which may have been the contribution factor based on other studies I have read. There is no hard evidence to support Selenium however it can’t hurt and probably does help a bit. I’m not too fussed about this one.

Vitamin D3 – 10mcg

Good. Finally, Vitamin D. Vitamin D is one of my top ingredients along with Zinc and D-aspartic acid. 3332 IU of Vitamin D was given to 200 men daily over the course of a whole year. 163 of those men finished the study and there were significant increases in free testosterone levels.

Further studies have actually shown that Vitamin D actually helps by retaining testosterone in the body and stopping the conversion of some testosterone into estrogen, which is a normal process. So Vitamin D helps the body to retain testosterone rather than straight up produce it. This is why it works so well with ingredients such as DAA or Zinc which help the body produce more testosterone. Vitamin D then helps the body retain that increased testosterone.

So Vitamin D is super effective and I love seeing it in the ingredients list, however here’s what I find confusing. 10mcg is a super small amount. Testogen has been super generous in its DAA and Zinc dosages, so why is it being so frugal with Vitamin D? To give you an idea of how small this dosage level is, I would like to see 1500mcg in a good test booster. Vitamin D is one the most common deficiencies in men which is often the cause of low t levels, that’s why I like to see healthy dosages of Vitamin D.

I found that this testosterone booster does not contain all my favorite ingredients in the appropriate dosages. However it does contain D aspartic acid, vitamin D and Zinc all of which are powerful test boosters. This is a decent formula for the price tag but it is not the highest quality on the market.

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.

Testogen Results

I did find it difficult to find accurate reports of user results online – especially before and after pictures. I did find some third party Testogen reviews which were all pretty positive however had trouble finding a lot.

What Do I like?

  • Cheaper price tag
  • The high levels of D-aspartic acid
  • The inclusion of D-aspartic acid, vitamin D and Zinc

What Don’t I like?

  • Weird dosages – Zinc too high, Vitamin D too low
  • No Magnesium. Where’s the magnesium?



Honestly, coming out of the gate I liked my initial glance at the ingredients formula: DAA, Zinc and Vitamin D are all present. But on deeper analysis I wouldn’t take this booster myself. This is because of the low levels of Vitamin D and absence of Magnesium.

This product is Ok and will probably do the job fine, however I would not take it personally as there are more complete product formulas on the market. Testogen is a good option if you are on a strict budget and want something a bit cheaper.

My Score


Where to Buy Testogen

You can only find Testogen for sale at the official website. Unfortunately you can not find Testogen at GNC, Amazon or any other big online retailers.

What I am Currently Taking

Personally, I am currently taking Prime Male and have seen lots of benefits from taking it including increased libido and energy levels. You can read my full review on that over here.

If you are looking for a product to primarily help with muscle gains I would probably go with TestoFuel, it’s a little more expensive but I would feel more comfortable with the dosages personally plus it contains a more complete ingredients formula. Read my review on TestoFuel.
