Quick Take: First things first. GAT Testagen has 29 ingredients so you can bet your behind this is going to be a long review. But really, it’s not going to be that long because not all 29 ingredients do sh*t for testosterone or manly health for that matter. The formula also has 2 prohormones that essentially make it unusable by the professional athletes. Regardless, with this huge number of ingredients, at least a few are bound to work for testosterone. The question now becomes, “Which ones?” Let’s get to the review and find out.
- Testagen is a testosterone boosting product of the old-timer in bodybuilding supplements: GAT
- Advertised on their label as a “premium testosterone amplifier”
- Also on their label, the product claims to be “fast acting”. And with Testagen’s Absorption Blend, they seem to back it up.
- Testagen’s Mass, Strength & Size Formula is packed full of quality herbs and quite a few are even adequately dosed
- I tried looking for Testagen in GAT’s website but I couldn’t find it. A lot of online retailers have also discontinued selling the product and the remaining sellers having just a few more in stock. This tells me that the Testagen MIGHT not actually be manufactured anymore.
- The online shops and retailers that you can still buy Testagen from include Amazon. Apparently, GNC doesn’t have the product anymore.

GAT Testagen’s T-Boosters & Other Ingredients
This is going to be pretty long. Really, I would’ve preferred that you’d read through the entire review but I’ll save you some precious minutes and this time, allow you to just skip through this section and go directly to the Formula Analysis part. If you have a lot of time on your hands though, feel free to read this.
Vitamin’s and Minerals
- Vitamin E – Has a number of health benefits due to its antioxidant and anti-inflammatory properties but by no means is this a testosterone booster.
- ZMA – Testagen manages to squeeze in 3 ingredients that make up the legendary ZMA. Unfortunately, they aren’t given in their best forms. Zinc Oxide and Magnesium Oxide are the cheapest and worst absorbed forms of these minerals. Vitamin B6 also isn’t at its best here. Their dosages look adequate though.
- Selenium – Being an antioxidant, it has the capacity to protect cells from damage. Also, the human body doesn’t need a lot for us to feel its benefits. Regardless, still no T-boosts here.
- Chromium – Similar to Selenium, the human body doesn’t require a lot of chromium. This ingredient helps turning the food we eat such as fats, protein, and carbohydrates into energy.
Testagen Mass, Strength & Size Formula
- Prohormones – 3β-Hydroxy-5-androsten-17-one & 3-(1H-indol-3-yimethyl)-1H-indole. Excuse me while I rest my eyes. That was a bit hard to read, wasn’t it? But if we’re not using scientific names here, those two ingredients would simply be Epiandrosterone & DIM. The former is believed to convert to DHT while also possessing anti-estrogenic properties but at just 20 mg, it’s probably just paper weight. DIM on the other hand, is a naturally existing compound found in broccoli that is also believed to inhibit aromatase activity. Although, research surrounding this ingredient seems to be centered on women.
- Beta-Sitosterol – According to this study, Beta-Sitosterol has been used to treat Benign Prostatic Hyperplasia. Essentialy, this could be good for prostate health.
- Ipriflavone – This is a substance derived from Soy. According to some articles I’ve read, this is apparently a safe steroid (whatever that means) popularly used in bodybuilding for increased metabolism. However, evidence is pretty hard to find as most studies focus on osteoporosis in women.
- 2-aminoethanesulfonic acid – Otherwise known as Taurine, it is considered as a “very essential” amino acid. According to this study, Taurine is frequently found in energy drinks and has shown some evidence of improving athletic performance. However, this needs to be studied further. That said, it doesn’t seem to do much for masculine health or testosterone.
- Maca – Not a T-booster, but a great ingredient for enhancing energy and sex.
- Asian ginseng – Standardized to 25% ginsenosides, Asian or Panax Ginseng is a great herb for masculine health. In terms of testosterone, it MIGHT boost it by reducing levels of stress.
- Paulinnia Cupana – More commonly known as Guarana, it’s commonly used for weight loss, energy, and improving athletic performance.
- Arctic Root – standardized to 3% rosavins, Arctic Root is also better known as Rhodiola. This plant has the ability to protect levels of testosterone from the depleting effects of stress.
- Puncture Vine – Better known as Tribulus Terrestris, this has been standardized to 45% saponins. It’s one of the most common ingredients you’ll see in testosterone boosters but it doesn’t actually boost testosterone. Instead, it’s a powerful libido booster which could also enhance physical prowess.
- Wild yam – This article states a lot of health benefits from this ingredient. In terms of men’s supplements, DHEA is derived from Wild Yam but apparently, taking Wild Yam isn’t the same as taking DHEA. Honestly, I don’t know why it’s even here.
- Cnidium monnieri – So this plant’s active compound has similar effects to that notorious blue pill back in the day. I’m talking about the blue pill that rhymes with Niagra here. However, it’s effects on testosterone have yet to be researched.
- Citrus paradise – Or grape fruit concentrated at a 40:1 extract. It’s believed to be a fat burner but according to studies, it only offers mild fat burning.
- Mucuna pruriens – One of my favorite natural testosterone boosting herbs because of its active ingredient L-Dopa. It increases LH production which signals for the release and synthesis of testosterone while also decreasing levels of prolactin which can drive down testosterone.
- Fenugreek – a potent herb for libido and strength but it also acts as a testosterone booster by inhibiting aromatase and 5a-reductase activity.
- Beta-alanine – an amino acid that can aid in gaining lean muscle.
That was a long list, right? But that wasn’t all that there is to that blend. There’s still Cyanotis vaga and Shi Shi. I really couldn’t find much about those ingredients and the things I found were essentially useless to male health.
Testagen Absorption Blend
- Flaxseed – It doesn’t look like it affects nutrient absorption by any means. However, it is good for cardiovascular health.
- Ginger – Again, I don’t understand how this could enhance absorption.
- long pepper – This article lists a number of health benefits from long pepper but really, I still don’t understand how it enhances absorption.
- Fenugreek – Well, what do you know? More Fenugreek. Check above section.
- Bioperine® – Finally. This branded form of Piperine is strongly linked with enhanced absorption.
GAT Testagen Directions
Take 2-3 tablets with breakfast and another 2-3 with lunch daily. After 6 weeks of use, take a one month break then repeat the cycle.
That was a long list and finally, we’re done with it. I mean, you won’t believe how much research I had to go through to get to this part. In reality though, not all of those ingredients are beneficial to a testosterone boosting supplement such as Testagen.
Starting with the vitamins and minerals, there’s not a whole lot of testosterone boosting that goes on in here with the ZMA trio being the only notable ingredients. Although they each look like they’re adequately dosed, Testagen chooses their worst forms. This is wasted potential for what could’ve been an extremely solid addition.
Moving on, Testagen’s Mass, Strength & Size Formula covers a total of 18 ingredients but out of those 18, only a few are considered testosterone boosters. Starting with the prohormones, Epiandrosteronel, even at a meager 20 mg, can still trigger a positive on urine and blood samples that professional athletes are required to take. This is unfortunate considering that this prohormone needs at least 300 mg to be effective. Essentially, Testagen shrinks their available demographic by adding a banned substance that doesn’t seem to do anything. DIM on the other hand, MIGHT work as an aromatase inhibitor but it’s mainly tested on women. Pretty questionable to say the least.
The only testosterone boosters on that list (or at least have the potential to influence or protect testosterone) are Beta-Sitosterol, Asian Ginseng, Rhodiola, Mucuna Pruriens, and Fenugreek. Some, such as Maca, Guarana, Tribulus, and Beta-alanine are still valuable additions even without boosting testosterone for either use in bodybuilding by enhancing performance and stamina or for bedroom purposes by increasing libido. The rest of the ingredients in this list have very little evidence surrounding their benefits or simply have no place being in a testosterone booster.
With regards to Testagen’s Absorption Blend, all you have to look at is Bioperine®. I’m not exactly sure why those other ingredients are here. Regardless, Bioperine® is not a testosterone booster by any means BUT by enhancing the absorption of the other ingredients, this alone makes the formula a whole lot better.
As a whole, I am impressed that some of the manly herbs in this list that require a lot of dosage are actually adequately dosed. Namely: Tribulus, Rhodiola, Fenugreek, & Ginseng. However, ingredients such as Mucuna Pruriens and Maca which would’ve been great additions too are barely getting their share of mg’s. Frankly, the formulators of Testagen look confused and just piled all the ingredients they could find into tablets and then called it a “premium testosterone amplifier”.
Does it Work?
Some of the ingredients here that receive adequate dosages do actually boost testosterone so, yes, I believe Testagen works. However, it doesn’t give you a full tank of testosterone like some of the best test boosting products do. Regardless, this supplement could still be beneficial to people looking to have a better gym experience and better sex. This seems like an appropriate target since the formula doesn’t seem too focused on testosterone as much as it does on muscle and libido.
- No side effects – From the customer reviews I’ve read, there doesn’t seem to be any reports of any serious side effects. However, I’d still advise you to follow the directed use as the sheer number of ingredients on this list might not work well for everyone.
- Bioperine® – Enhancing the absorption of the entire formula is always a good thing.
- GAT – It’s been in the bodybuilding supplementation bussiness for a long time. I’d say they’re a pretty reliable brand.
- Sex and muscle – …and a bit of testosterone. Because that’s essentially what you get here.
- Confusing formula – Just throw a bunch of herbs, vitamins, and minerals in a blender and hope it works.
- Epiandrosterone – Narrowing the target demographic by virtually doing nothing.
- Questionable Choices – Prohormones? Ipriflavone? Yam? Cnidium monnieri? Cyanotis vaga? Shi Shi?
- ZMA – The trio isn’t bad. It’s actually legendary. What’s bad is that they’re basically useless given the low bioavailability of their individual forms.
- Expensive – Honestly, I wouldn’t pay 60$ for this.
The Bottom Line
To conclude, I stand by my statement when I said that the formulators of Testagen looked confused. If their goal was to just stack a lot of ingredients and hope that some of it works, they were successful. But they weren’t that successful. You know what I mean? Some of the ingredients here actually do work. However, some of them don’t. Personally, I think it would’ve been better if GAT just focused on the ingredients here that promoted testosterone and masculine health like some of the most successful testosterone boosters in the market and scratch these other ingredients entirely.
