Straight-up daily muscle support with 1,000mg Ajuga and HICA
5% Nutrition Bigger by the Day is all about daily muscle-building help, not a pre-workout or hormone booster. The idea is simple: pair Ajuga whole herb extract as the star for anabolic support with HICA to fight muscle breakdown, green tea extract for body comp and antioxidant perks, and a bit of leucine to back up the muscle focus. The label shows everything clearly, which is huge in a world of 'anabolic' and 'myostatin blocker' supps that hide weak doses in prop blends.
The main player is 1,000mg Ajuga whole herb extract. Ajuga turkestanica is the plant often used for ecdysteroids like turkesterone, and lifters grab it for non-stim, non-prohormone help with training recovery, adaptation, and building lean mass. The thing is, this whole-herb version isn't standardized, so you can't pin down the exact active compounds like you could with a standardized extract. It doesn't mean it's junk, but raw material quality is key. At 1,000mg, that's a solid dose by weight, though without standardization, comparing to studies is tricky.
HICA, or alpha-hydroxyisocaproic acid, is in at 500mg. It's a leucine byproduct that helps with anti-catabolic effects – basically reducing muscle damage – and boosts recovery during tough training. You'll notice it more after back-to-back hard days when managing soreness matters. But heads up: most effective HICA uses in supps go higher than 500mg daily, so this is pointing in the right direction but not maxed out.
Key Highlights
- 1,000mg Ajuga Whole Herb Extract – the big star here, putting this in the natural anabolic category. Solid dose for daily capsules focused on recovery, lean gains, and adapting to training, not instant energy.
- 500mg HICA – a leucine spin-off for fighting muscle breakdown and aiding recovery. Great for guys stacking heavy sessions who need help keeping damage in check.
- 300mg Green Tea Extract – throws in body comp and antioxidant help, making this more than just a basic muscle builder. Helps chase leaner, harder results instead of just packing on pounds.
- 200mg L-Leucine – the key amino that kicks off mTOR for muscle building. Solid idea, but this dose is way under the 2.5-5g you see in studies for big effects.
- Fully open label – no prop blends or hidden amounts. In a space loaded with shady anabolic mixes, this lets you see exactly what's inside.
- No stims at all – no caffeine, no crashes, no issues with late workouts. Easy to stack with your pre, creatine, protein, or intras without overdoing it.
- Capsules all the way – super convenient if you're already mixing powders. Just pop these daily without messing up your shake routine.
- Muscle support without prohormones – uses plant extracts and metabolic helpers for training and recovery. Way more chill for folks avoiding heavy hormone stuff.
Who Is This For?
- Bodybuilders cutting who want non-stim daily help to keep mass during volume. Ajuga and HICA fit for protecting output and muscle over weeks, not quick energy.
- Intermediate lifters in growth mode with protein on point, adding recovery layers. Capsules build gradually, with 1,000mg Ajuga and 500mg HICA hitting adaptation, not instant wins.
- Evening trainers skipping heavy pres but wanting muscle supp. Stim-free means it works for late sessions without killing sleep like caffeine does.
- Athletes rebuilding post-break, regaining size without fat. Ajuga plus green tea leans it toward clean mass over bulk-anything.
- Vet supp users sick of prop blend 'anabolics.' This shows it all: 1,000mg Ajuga whole herb extract, 500mg HICA, 300mg green tea extract, and 200mg leucine.
- Physique guys on creatine and protein, adding anabolic support. Targets recovery and signaling, different from just calories or energy reload.
How to Use
Run this daily, not just gym days, for the buildup benefits. If it's 4 capsules, take 'em with 8-12oz water; with food if plants upset you. On training days, 30-60 mins pre is fine for consistency, but it's not about instant boosts. Rest days, pair with breakfast or a sure meal. No need to half-dose for stims, but start low if green tea bugs you. Stack with creatine, good protein, and maybe EAAs or leucine-rich food for synthesis. Don't rate it like a pre; add one if you need buzz or pumps. Store sealed, cool, and dry. No stims mean no forced cycling, but check every 8-12 weeks if it's still pulling its weight.
What to Expect
First 0-20 minutes, nothing much – no caffeine or pumps here. Early days are about feeling good knowing it's in your stack, not huge changes. Days 1-7, it's mainly building routine, maybe smoother recovery flow over big strength jumps. Weeks 2-4, you feel better workout flow, less piled-up fatigue, and trust in holding lean mass during hard pushes. If it clicks, it's steady progress through blocks, not a single epic session. Judge this over time, not one lift.

Frequently Asked Questions
What are the main active ingredients in 5% Nutrition Bigger by the Day?
The verified active formula includes 1,000mg Ajuga whole herb extract, 500mg alpha-hydroxyisocaproic acid (HICA), 300mg green tea extract, 200mg L-leucine, and 150mcg RAE vitamin A. If BioPerine® is present in the full commercial formula, its dose was not verified in the available data, so it cannot be fully assessed here.
Is Bigger by the Day a true myostatin blocker?
The product is marketed in that category, but the human evidence for true myostatin-blocking effects from ingredients like Ajuga or laxogenin-related positioning is not strong enough to make that the most evidence-based way to view it. A more honest description is daily natural anabolic-support and recovery-support.
Will I feel this product right away?
No. This is not a stimulant pre-workout and not a pump formula, so there is no reason to expect immediate energy or dramatic acute effects. The intended benefits are cumulative over weeks of consistent use alongside hard training and adequate nutrition.
Is the leucine dose in this product clinically dosed?
No. Leucine is one of the most proven muscle-protein-signaling amino acids, but the research-backed range is typically around 2,500-5,000mg. At 200mg, the leucine here is supportive, not a standalone clinical leucine dose.
What does HICA do in this formula?
HICA is a leucine metabolite used for anti-catabolic and recovery support. It is included to help reduce muscle breakdown pressure and improve recovery quality across repeated hard training sessions, although 500mg is below the more aggressive standalone HICA protocols used in some research.
Can I stack Bigger by the Day with a pre-workout?
Yes. This product is stim-free, so it stacks naturally with pre-workouts, pump formulas, creatine, and protein powders. In fact, that is one of its biggest advantages: it supports the longer-term recovery and adaptation side while your pre-workout handles acute energy and performance.
Should I take it only on training days?
Daily use makes more sense. Because the ingredients are designed for cumulative support rather than immediate effect, consistency on both training and rest days is the better strategy.
Is Bigger by the Day good for a cutting phase?
It can fit a cut well because the formula is aimed at lean-mass support and includes 300mg green tea extract for body-composition support. For lifters dieting hard, that combination is often more useful than relying only on stimulant-based fat burners.
How transparent is this formula compared with others in the category?
It is much more transparent than many natural anabolic formulas because the active ingredients are individually disclosed rather than hidden in a proprietary blend. That lets you evaluate the strengths and limitations of the formula honestly.
Is this product suitable for beginners?
It is not dangerous by design because it is stim-free, but it is probably not the first supplement a beginner needs. Most newer lifters will get more from protein, creatine, sleep, and progressive training before adding a niche muscle-support formula like this.
