PreSeries Lean Pre Workout Review
Lean is the perfect weight loss pre workout, made to encourage the body to use fat for energy while increasing thermogenesis.
It's rare to find a solid pre workout that not only makes it easier to lose weight but that can also increase performance without using an overwhelming amount of stimulants.
For overall improved function and energy, Lean is the perfect pre workout for those looking to be as healthy as possible.
Increases fat loss and energy by optimizing body functions.
Seems expensive but it's worth the cost.
Completely disclosed and transparent label of weight loss and performance-focused ingredients.
Can only be bought at one source.
Who Is Transparent Labs?
Transparent Labs is well known for producing full disclosed label supplements.
And yes that means even the “other ingredients”, the inactive ingredients, have disclosed dosages.
There’s 3 different pre workouts from TLabs and they are similar in profiles, but different for purposes.
First comes Bulk, the pre workout designed to support and optimize testosterone levels, muscle growth and gains.
Then Stim-Free, it uses the same formula as Bulk but without the stimulants (caffeine, and synephrine).
Finally, Lean, the fat loss powder that ignites fat burning by using a special thyroid support blend.
All 3 of these pre workout cater to serious athletes and bodybuilders who want to get the most out of their physiques without sacrificing or putting their health at risk.
Why Choose PreSeries Lean?
Like their other pre workouts, TLabs has put this pre workout at the front line of weight loss.
Very few pre workouts can attack fat from all angles like Lean does.
What makes Lean special is that it uses full clinical dosages of performance enhancing ingredients while making it something that doesn’t need reformulating for many years to come.
This means that Lean has been a top seller for weight loss for the past few years.
There aren’t that many pre workouts that have been using the same formula without major changes for a few years straight like Lean does.
Who's It For And Why You Might Not Like It
Anyone who trains, runs, or plays sports will enjoy using Lean.
While this pre workout is formulated for weight loss, it’s great as an all around and all purpose pre workout.
This is because it uses ingredients that not only optimizes performance but it also uses thyroid supporting ingredients so your body functions at it’s best.
With optimal thyroid functions, fat loss and energy will remain high and at it’s top function.
You can see Transparent Labs means business.
The list is huge and the dosages are equally great.
Some notable differences between this and Bulk is that this has less BCAA’s and beta alanine
The reason why it has less BCAA’s is to reduce the total calories as BCAA’s have about 5-7 calories.
It isn’t much, but it might matter to some people.
The lower beta-alanine content might make Lean more appealing over Bulk as it’ll cause less tingles.
And it doesn’t have creatine or taurine, which will lead to that “dry” look that people try to achieve when shredding.
Lean makes a great pre workout even if you’re in the bulking process.
Between this pre workout and the others, the differences are huge, from the fully disclosed ingredient label to the natural flavoring.
It even has the basics and full days worth of iodine, zinc, chromium, selenium and copper.
These minerals are important for a healthy and functioning body, it makes it even more important to have if you’re on a strict diet that might strip away these nutrients.
Lean Weight Loss Support
Lean wouldn’t be a weight loss pre workout without these “cutting” ingredients. First we’ll cover the weight loss ingredients then we’ll jump to the other ingredients.
Iodine Chelate (225mg)
With all of the technology we have today, we have less of a reason to be in the sun.
For properly functioning thyroids, Iodine helps achieve that.
Poorly functioning thyroid will lead to weight gain, body composition, and poor resting metabolism.
Iodine will help increase thyroid function and will prevent those negative things from happening.
Guggulsterones is found in Guggul and it’s the main active component of it.
It’s used to fight off liver dysfunction, obesity and fat storage. It also helps enhance absorption of Iodine.
Zinc AAC (30mg)
All athletes from any background will require zinc, even more than regular people because with high intensity exercise, comes with decreased zinc levels.
It’s needed for properly and optimized immune system support, decreases unhealthy food cravings, and helps optimize testosterone levels.
Copper AAC (1mg)
Copper helps enhance energy and is needed to optimize metabolism and thyroid function.
Like Guggulsterones, copper will enhance absorption of iodine.
Chromium Picolinate (200mcg)
Chromium picolinate is a perfect ingredient to have a weight loss supplement but it’s highly underrated.
It’s been shown to regulate blood sugar, and suppresses appetite so you’ll be less likely to have junk food cravings. With stabilized blood sugar levels, you’ll be more likely to stick to your diet.
And finally we have an essential amino acid, selenium helps by enhancing glucose uptake and optimizes metabolism.
Citrulline Malate (6g)
Endurance, strength, pumps.
Citrulline malate allows you to maximize your power output by decreasing and eliminating lactic acid content in your muscles.
This works similarly to beta alanine.
And it’s comparable to agmatine when it comes to pumps.
It’ll help increase pumps, you’ll easily get more muscle hardness and all day pumps from this dose alone.
For power and strength, betaine is an excellent choice.
It works like creatine and it also increases muscle size while stimulating muscle growth.
Betaine is found in beets, and it’s been shown to optimize HGH while decreasing cortisol, leaving you in an optimal state for weight loss and muscle gains.
Betaine will help increase performance by decreasing fatigue, allowing you to push for more reps before feeling fatigued.
BCAA’s are the building blocks of protein.
When you’re on a strict diet, you won’t be able to push as hard because your calorie intake will be much less.
By increasing protein synthesis, BCAA’s will help keep you in an optimal state for muscle gains even if you’re shredding.
Beta Alanine (1.5g)
Known for the tingles, beta alanine decreases the lactic acid build up that occurs from high exertion.
By doing this, it’ll help delay fatigue and allow you to push for more reps and weight while increasing strength and muscle gains.
Like creatine, beta alanine takes time to saturate and work.
It should be an ingredient that is supplement for regular use.
This dose is a bit low but you should have beta alanine in bulk anyway to make the most out of it.
N-Acetyl L-Tyrosine (600mg)
L-Tyrosine increases alertness, focus and kicks up dopamine production.
It’s an important ingredient to have for optimal energy.
Although it’s a non-stimulant, it’s often paired with caffeine because of its efficiency.
Choline Bitartrate (500mg)
Choline is a nootropic that helps enhance focus and it works well when it’s combined with betaine.
On a strict diet, you may have reduced attention span, but with choline bitartrate you have better mental functions.
When you need prolonged focus and energy then you’d be right to choose theanine.
Theanine is an amino acid that’s found in green tea, and it produces a relaxing effective that puts you in the zone while not having any sedative effects.
So you’re at the top of your mental functions without feeling jittery or sleepy.
At 360mg, it’s a huge dose and it’ll surely lead to some long lasting focus.
A low but effective dose of 180mg caffeine will produce some nice energy without any jitters, especially since it’s combined with theanine.
Hordenine and the other high doses of stimulants here still makes Lean a moderately high stimulant-weight loss pre workout but without causing jitters and being safe enough for any lifter from any level to take.
The next ingredient (mucuna pruriens) will help increase adrenaline levels.
Mucuna Pruriens (70mg)
Mucuna pruriens here is L-Dopa, and it increases catecholamines production: dopamine, norepinephrine, and epinephrine.
Like ephedrine, it’ll increase energy and enhance mood while increasing testosterone and decreasing prolactin production.
In other words, although you’ll be cutting and putting yourself in a caloric deficit, your testosterone and mood will be optimized thanks to L-Dopa.
L-Norvaline is used for increasing nitric oxide levels.
It’s a derivative of the BCAA valine, it works by preventing arginine from breaking down in the blood.
This means when L-Citrulline is increasing nitric oxide level, Norvaline will protect those levels from dropping down.
At 60mg, it’s a decent dose and will ensure you’re getting the most out of citrulline here.
Synephrine works like ephedrine, but it’s known to be a safer alternative.
It works as a metabolic enhancer and a stimulant with beta-receptor, which releases more fatty acids so your body uses it for energy.
It’ll also suppress appetite and increase metabolism.
50mg is quite a high dose but it’s still safe.
Hordenine extends the life of stimulants.
When it’s used with caffeine or other stimulants, it’ll smooth out the energy so it not only lasts longer but it takes out the traditional crashing that’s associated with stimulants.
Like synephrine, it releases fatty acids for your body to use as energy.
With so many ingredients, there’s bound to be some small absorption issues.
There’s so much to digest.
Luckily BioPerine helps enhance absorption of all the ingredients here.
Check out this list:
At first, Lean may seem expensive, but for what you get, it is worth the cost.
Comparable pre workouts are slightly more expensive, especially considering that the cost of Lean goes down when you buy multiple bottles.
Lean Your Way Out
With so few weight loss pre workouts out there, Lean easily makes it at the top recommendation for an future-proof weight loss pre workout.
As we see supplements with ephedra and DMAA slowly disappearing from supplements, Lean paves the way with a future-proof formula that is unlikely to be formulated anytime soon.
It uses a fully transparent formula that attacks weight loss from several angles.
