Man Sports has released a unique supplement, Lean Ph.D, a nootropic and a fat-burner combined.

Lean Ph.D is designed to improve weight loss while also providing enhanced focus and clarity at the same time. Combing cognition-boosting and fat-burning ingredients is an interesting niche to be in. I took a closer look at Lean Ph.D to see if it is capable of producing both benefits.


Lean Ph.D is packed with several ingredients. Instead of running through each and every one of them, I highlighted a couple key ingredients that stuck out to me during my research:

Acetyl-L-carnitine is a main ingredient in Lean Ph.D, an ingredient which is used to improve energy production, [1] so you can have more energy to help you get through the day.

Lean Ph.D also includes undisclosed amounts of N-Acetyl-L-Tyrosine, or NALT for short. This component is a more soluble form of L-tyrosine, an amino acid that is often supplemented with to bolster cognitive function.

Like most fat-burners, Lean Ph.D also includes 100 mg caffeine anhydrous, a stimulant used both to kick start metabolism and also improve focus.

The proprietary blend in Lean Ph.D also provides green tea and nelumbo nucifera, which have been used to increase fat-loss and curb appetite, respectively.

Overall, the ingredients in Lean PhD include ingredients both to improve focus and also weight-loss efforts. The only downside is that other than caffeine, the rest of the ingredients are included in a proprietary blend, so it’s impossible to gauge whether these ingredients are formulated effectively.

How To Use Lean Ph.D

Lean Ph.D should be used on an empty stomach before the first meal of the day. You can take anywhere from 1-2 capsules per day; however, I recommend starting with 1 capsule to assess tolerance and see how you respond to the ingredients.

While supplementing with Lean Ph.D, you should make sure to consume plenty of water. Also, third-party websites indicate you shouldn’t supplement with Lean Ph.D for more than 12 weeks at a time without allowing a 4-week break.

I got to try Lean Ph.D for a couple days. I obviously didn’t notice any weight-loss benefits in such a short period of time, but I did notice a nice, subtle boost of energy for a short time after supplementing with it.

If you use Lean Ph.D for an extended period of time, I am convinced that you will notice some weight-loss benefits when coupled with exercise, as well as some noticeable differences in energy levels.

Final Thoughts

Lean Ph.D is formulated with effective ingredients, and based on that alone, it may be worth looking into if you want to boost your fat burn and get a nice kick of energy. As I previously mentioned, whether the ingredients are underdosed or not, I am not sure.

You can get 90-capsules for about $45, which isn’t a bad deal. That means, essentially, each bottle can last anywhere from 90 to 45 days, depending on how many capsules you take per day.

Lean Ph.D may not work for everyone. If you don’t respond well to caffeine, you may want to avoid this product; however, it provides a relatively moderate amount per serving compared to other fat-burners.
