3. TestoFuel
Natural and very effective each time we’ve used it. Also allowed us to pass all competition drug testing.
About TestoFuel
TestoFuel is an excellent testosterone booster that is designed for strengthening athletes and body builders. It is effective in enhancing the buildup of muscles.
We didn’t just get good results though, but also a very quick delivery and extra bottle free with our trial order. The order also came with a nutrition and workout guide. We didn’t use this but it seemed good.
Effects we got from TestoFuel Supplementation after 30 days:
- Increased levels of free testosterone
- More muscle mass and better performance (1RM went up)
- Confidence increased
- Best rest ever, less DOMS
- Felt 18 years old again

Our Experience on TestoFuel:
TestoFuel is the last word on testosterone boosters in the current market. You’ll see all kinds of blends and products all over the internet claiming to be ‘scientifically proven’, but in reality, these studies are thin and often performed on rats.
Our order from TestoFuel was pricey, but it was delivered quickly and it was very easy to order.
1 week on TestoFuel led to a revitalized feeling of energy and we slept a whole lot better. We had frustrations remembering to dose 4 capsules daily at first, but soon got into the swing of it.
By week 2 we felt liked we’d been missing out by trying other testosterone boosters. Our gym performance felt better, bedroom performance was even better than that. And we were horny as hell.
At the end of the first month we’d seen good muscle gains and a surprising loss of belly fat. Recovery and sleep had also improved immeasurably.
We cannot recommend this product enough, it’s still holding it’s crown as THE testosterone booster of 2018.

The good:
-
- Proven muscle building supplement
- Scientifically backed and cGMP manufactured
- 90 day money back guarantee – Worth the punt
-
- Contains a large dose of Vitamin D and D-Aspartic Acid
-
- Offers a larger 200 milligram dose
-
- Great worldwide customer reviews
- All ingredients are researched and proven, read the studies yourself!
The bad:

4. Prime Male
In the second spot of our top 5 testosterone boosters list is Prime Male. This supplement is specifically formulated for men above the age of thirty. It is designed to reverse the effects of aging that cause the decline of testosterone levels that all men experience.
On average, men lose 1% of their testosterone levels every year beginning from the late twenties. Although that might not seem like much now, the numbers pile up- and before you know it- you won’t be gaining or losing as much as you used to.
For a lot of men, it’s their own personal set of hell. To lost the ability to do something that they were able to do so easily before.
The results of using this supplement include increased strength and muscle, a boost in sex performance and drive, reduced body fat, improved mood, more energy and other health benefits linked with the increased production of testosterone.
The other benefit of Prime Male is higher bioavailability, meaning that the body readily absorbs the nutrients in this supplement. This is particularly beneficial because the ability to absorb nutrients in supplements and food deteriorates naturally with age.
If you are thirty years of age or older and you want to regain some of the energy, athletic performance and strength you had when you were younger, we recommend taking Prime Male.
The Good:
-
- Specifically designed for men aged thirty and above
-
- Higher bioavailability
-
- Premium quality
-
- Contains a high amount of natural ingredients, which are proven to be effective
-
- No fillers
- Excellent customer reviews
The bad:
-
- Unsuitable for vegans or vegetarians
- You can only buy it online
