EVERBUILD L-LEUCINE 5000 – POWDER
EVERBUILD L-LEUCINE 5000 it is a supplement of Pure L-Leucine in free form, the most powerful essential amino acid for stimulating muscle protein synthesis (MPS). With a clinical dose of 5 grams per scoop, this product provides the optimal amount of leucine needed to activate the mTOR metabolic pathway, the main anabolic switch of the human body. Considered the most important of the three BCAAs (branched-chain amino acids) for its anabolic and anti-catabolic properties, leucine is essential for building and maintaining lean muscle mass, accelerating post-workout recovery and reducing catabolism at critical times such as waking up in the morning or after intense sessions. Ideal for bodybuilders, powerlifters, strength athletes and anyone looking to maximize muscle growth.

What is L-Leucine and Why is it the "King of Amino Acids"
The L-Leucine it is one of the 9 essential amino acids (EAA) and is part of the 3 BCAAs (leucine, isoleucine, valine). It is considered the most anabolic amino acid for several reasons:
Scientifically documented mechanisms of action:
-
Activation via mTOR (Mammalian Target of Rapamycin): Leucine is the only amino acid that directly activates mTOR, the main regulator of muscle protein synthesis. This metabolic pathway triggers the translation of mRNA and the construction of new muscle proteins.
-
Leucine threshold for MPS: At least they are needed 2.5-3 grams of leucine in a single meal/dose to reach the "leucin threshold" and maximize protein synthesis. EVERBUILD provides 5 g, well above the optimal threshold.
-
Anti-catabolic properties: Blocks muscle protein degradation (MPB) by inhibiting the ubiquitin-proteasome system, the main mechanism of muscle breakdown.
-
Enhanced anabolic signal: Even in the presence of sub-optimal amounts of total protein, adding extra leucine can "rescue" the anabolic response.
-
Insulin regulation: Leucine stimulates insulin secretion from the pancreas, which in turn promotes the uptake of amino acids and glucose into muscle cells.
-
Energy support: Under conditions of glycogenic depletion, leucine can be oxidized directly in muscles to produce energy.
10 Main Benefits
-
Maximum stimulation of protein synthesis: 5 g of leucine activates mTOR at maximum level for muscle growth.
-
Accelerated post-workout recovery: reduces DOMS (muscle soreness) by 20-30%.
-
Preservation of lean body mass in a caloric deficit: powerful anti-catabolic signal during cutting or low-calorie diets.
-
Increased strength and performance: anabolic support promotes neural adaptations and hypertrophy.
-
Reduction of protein breakdown: blocks catabolism during intense training, overnight fasting or physical stress.
-
Optimization of sub-optimal protein meals: "complete" meals low in protein or vegetable sources (deficient in leucine).
-
Support protein synthesis in the elderly: counteracts sarcopenia (age-related muscle loss).
-
Direct muscle energy: Leucine can be oxidized in muscles for ATP without passing through the liver.
-
Synergy with other amino acids: enhances the effect of EAA, BCAA and protein powder.
-
Zero wasted calories: 20 kcal per dose, all intended for anabolic signal, no fillers.
Dosage and Method of Use
Standard Dosage:
-
Clinical dose: 1 scoop (5 g) for optimal mTOR activation
-
Frequency: 1-3 times a day depending on the goal
-
Assumption: dissolve in 200-300 ml of water, juice, or protein shake
Optimal Timing:

-
Dose: 5 g leucine + 20-25 g whey protein/isolate + 30-50 g carbohydrates
-
Objective: Maximize spike protein synthesis and recovery
-
Why: The extra leucine guarantees threshold exceeding even with sub-optimal proteins
2. PRE-WORKOUT (15-30 minutes before):

Ideal for: fasting or early morning training
3. INTRA-WORKOUT (during workouts >60 minutes):
-
Dose: 5 g leucine + electrolytes + carbohydrates
-
Objective: Reduce muscle catabolism, support energy
-
Ideal for: high volume sessions, metabolic training, endurance
4. ON WAKING UP IN THE MORNING (on an empty stomach):
-
Dose: 5 g leucine + 10-15 g EAA
-
Objective: Block nocturnal catabolism, restart protein synthesis after 8-12 hours of fasting
-
Synergy: Waits 30-60 min before full breakfast
5. BETWEEN MEALS (to prolong the anabolic window):
-
Dose: 5 g leucine
-
Timing: Mid-morning or mid-afternoon (3-4 hours after last meal)
-
Objective: "Restart" protein synthesis between main meals

FAQ – Frequently Asked Questions
1. Is leucine alone sufficient or are other amino acids also needed?
Leucine is the "trigger" (switch) of protein synthesis, but the other 8 EAAs also serve as "building blocks" to build proteins. Ideal: leucine + complete protein or EAA.
2. Can I replace BCAAs with just leucine?
For short term yes (leucine is the most important). Not for prolonged use: isoleucine and valine have their own roles (energy, recovery, immune system). Better complete BCAAs or leucine + EAAs.
3. How much leucine is in 30 g of whey protein?
~2.5-3 g. Adding an extra 5g brings the total to 7.5-8g, maximizing anabolic response.
4. Does leucine make you fat?
No, it only has 20 kcal per dose. Stimulates muscle protein synthesis, not fat accumulation.
5. Can I use it during intermittent fasting?
Technically it breaks the fast (stimulates insulin and mTOR). But many IF athletes use it pre-workout fasted to preserve muscle (acceptable compromise).
6. Does it taste bad?
Yes, pure leucine is bitter. Tip: Mix with fruit juice, flavored protein shake, or add natural sweetener (stevia).
7. Is it safe for daily use?
Yes, when combined with adequate protein diet or EAA. Do not use 20+ g leucine isolate per day for months without balancing with other amino acids.
