At first glance, you might be scratching your head, wondering which pre-workout supplement to go for.
You've got PreSeries Lean on one side, specifically formulated to kickstart weight loss and rev up glucose metabolism.
Then there's Bulk, your go-to companion for bolstering strength and muscle.
Both are champs when it comes to boosting mental energy and focus.
But here's the kicker: Bulk takes the crown for muscle hypertrophy goals, while Lean is your best bet for torching fat.
And while it might seem like Lean is just playing copycat with its ingredients, it's actually packing high-quality mineral sources and ingredients specifically designed to supercharge fat metabolism.
And here's a little cherry on top: use the discount code FITFREK for a sweet deal.
We'll explain the main differences, advantages, and disadvantages of everything to help you decide on which pre-workout to go with.
Bulk is your go-to for cranking up testosterone production, while Lean is all about firing up thermogenesis to aid weight loss.

Both of these have one thing in common, they contain ergogenic aids and they don't use artificial colors or sweeteners.
Transparent Labs designed Bulk with more muscle-building ingredients that will help maximize performance mentally and physically, while Lean is made more with mental enhancers and components that help metabolize fat from various angles.
Bulk has vitamins for testosterone and muscle-building support, including vitamins D3, B6, zinc, and boron.
While Lean also has zinc, it also uses important ingredients for fat loss like iodine, selenium, copper, and chromium.
If you're deficient in these ingredients, you'll likely struggle to lose weight and control your cravings.
If you're looking for a solid pre-workout, both, Lean and Bulk, are great options.
Bulk is better designed if you're looking for a complete pre-workout to help improve your workouts.
It has everything needed for reducing fatigue, increasing strength, and boosting cognition functions.
Lean is good but it's more designed as a thermogenic as it contains ingredients that'll support better insulin function and more fat metabolism, and is just better for weight loss.
Which Pre-Workout is Better For Pumps?
Bulk is better for pumps as it has the full dose of betaine at 2.5g but otherwise, both are great for pumps.
Which Pre-Workout Is Better for Energy?
Both pre-workouts have the same amount of caffeine but Bulk has a slight edge due to the combination of tyrosine and Alpha GPC, as Lean only uses choline for focus support.
Which Pre-Workout Should I Get?
If you're just looking for a solid pre-workout, you can't go wrong with either although Bulk has a slight edge as something that will help maximize endurance and energy.
If you're trying to lose stubborn fat, or just trying to lose weight in general, you'll enjoy Lean more.
As a beginner or any level, both pre-workouts are great options.
Containing over 22g per serving, Bulk contains full doses of ergogenic aids and a range of nootropics as well as stimulants to help enhance energy.
Bulk is made to be the best pre-workout for anyone looking to increase their workout performance.
Using ingredients that'll increase power, strength, and endurance, it'll provide quite a boost for anyone looking to maximize their results in the gym.
With over 20g per serving and 30 full servings, Bulk is a solid choice as a pre-workout.
Citrulline is dosed at 6g, which will help with pumps, and beta-alanine will reduce the lactic acid build-up that occurs from high-volume sets.
There's also a nice dose of BCAA's to help prevent catabolism and there's a 2.5g dose of betaine anhydrous to help maximize size and strength as it works similarly to creatine.
With a mix of stimulants coming from caffeine, theobromine, and caffeine malate, there's a nice long-lasting source of energy.
It also has nootropics to help maximize focus and mind-to-muscle connection with 1g tyrosine and 300mg AlphaSize Alpha GPC.
Overall, Bulk is a solid pick for someone looking to maximize their performance in the gym.
The only reason why you wouldn't pick Bulk is because of its premium pricing but you can knock off 10% with discount code FITFREK.
Lean is designed to support weight loss from multiple angles, including improving insulin sensitivity and glucose metabolism.
Lean is a thermogenic pre-workout hybrid that combines ingredients that will not only increase performance but also fat burning.
When it comes to ergogenic aids, there's a lot in common with Bulk as it still has citrulline, beta-alanine, betaine, and caffeine.
But instead of using 4g of beta-alanine, it uses 2g, and it has 1.5g betaine instead of 2g.
And Lean also uses 630mg of acetyl-l-carnitine which helps convert fat into energy, increasing fat metabolism.
Like all Transparent Labs supplements, this is clinically dosed and there are no artificial ingredients.
The minerals in Lean will help optimize thyroid function, improve insulin sensitivity and increase fat metabolism.
In fact, these minerals are highly underrated and are a must even if you are using a fat burner with very strong stimulants.
Just check out the science and research behind Lean's ingredients here.
Lean is a pre-workout that is formulated to help keep fat off and performance, both physically and mentally, elevated in the gym.
The only downside is the premium pricing but you can use our discount code FITFREK.
As someone who mostly uses very strong pre-workouts, Bulk helped me push through without putting a huge demand on my cardiovascular system.
Hard pre-workouts usually give me very intense energy which can interfere with sleep even if it's taken long before the evening.
So using Bulk allowed me to sleep better at night and still have great workouts during the day.
The energy is just enough.
So I can appreciate the caffeine staying under 300mg, and it comes from 3 different sources so it isn't just plain caffeine.
My performance also feels solid.
That's what I like about Bulk, it's reliable, I can use it often without consequences of withdrawals or side effects like jitters and such.
Using Lean has made me realize something...
The minerals in Lean are highly important for fat loss.
I've used all sorts of fat burners and thermogenic but without these minerals, I just don't feel right.
The reason for this is that the minerals in Lean are extremely important for weight loss management.
It helped me keep cravings in check and it seems to help me have more energy as it helps converts fat into energy.

When it comes to effectiveness, both Bulk and Lean have their unique strengths, tailored to different fitness goals.
Let's dive deeper into what makes each of these pre-workout supplements stand out.
Bulk is your ally in the quest for muscle gain. It's packed with ingredients that support muscle growth and strength.
One of the key components is BCAAs (Branched-Chain Amino Acids), which are crucial for muscle protein synthesis.
This means they help your body build and repair muscle tissue, promoting muscle growth over time.
Bulk also contains Beta-Alanine, an amino acid that helps fight muscle fatigue.
This means you can push harder and longer during your workouts, leading to greater muscle gains.
Plus, the inclusion of Taurine aids in muscle recovery, helping you bounce back faster after intense workouts.
On the other hand, Lean is designed for those looking to shed fat and get lean.
It includes ingredients like Synephrine and Hordenine, which are known to boost metabolism and promote fat burning.
This means that while you're working out, your body is more efficient at using fat stores for energy, helping you lose weight.
Lean also contains ingredients that support glucose metabolism, which is crucial for weight loss.
Efficient glucose metabolism means your body is better at using the food you eat for energy, rather than storing it as fat.
Both Bulk and Lean are effective in their own ways.
If your goal is to gain muscle mass and strength, Bulk is the way to go.
If you're aiming to lose weight and get lean, Lean is your best bet.
Remember, the effectiveness of these supplements also depends on your diet and workout regimen.
They are designed to enhance your performance and results, but they can't replace a balanced diet and regular exercise.
When it comes to choosing which pre-workout to go with from Transparent Labs, you should consider your goals.
