Ajuga-powered muscle helper with HICA, epicatechin, and no hidden doses.
5% Nutrition Bigger by the Day is a no-stim muscle support capsule that keeps things simple: build a better muscle-building vibe without hormones, caffeine, or hidden blends. It's straightforward with full disclosure. Ajuga whole herb extract hits at 1,000 mg as the star, backed by 500 mg HICA, 300 mg green tea extract with epicatechin, 200 mg L-leucine, vitamin A, and BioPerine® to help it absorb. This isn't a loaded mass gainer or a pre-workout in disguise. It's a targeted add-on for lifters who already have the big stuff handled.
Ajuga extract is the main player here for muscle support. In gym supplements, Ajuga turkestanica gets used for turkesterone and similar compounds that aim to boost protein synthesis, recovery, and lean gains. Human studies are still building, so it's more promising than locked-in proven, but that 1,000 mg dose is solid and clear on the label. What you'll notice is better flow in your training: less drag, quicker bounce-back from tough workouts, and extra help for body comp during heavy phases.
HICA, that's alpha-hydroxyisocaproic acid, comes in at 500 mg. It's a leucine byproduct that helps cut down on muscle breakdown and eases soreness, based on studies looking at recovery from intense sessions. This fits smart because it adds real protection, not just repeating the same idea.
Green tea extract at 300 mg, standardized for epicatechin, brings a fresh angle. Epicatechin gets studied for better blood flow and muscle function
Key Highlights
- 1,000 mg Ajuga whole herb extract is the heart of this formula. It's the key for turkesterone-style support, helping with lean gains and recovery without stims or hormones.
- 500 mg HICA brings real muscle protection. As a leucine metabolite, it's there to help keep your gains safe during tough training or when calories are low.
- 300 mg green tea extract with epicatechin adds smart performance vibes. Epicatechin helps with blood flow and muscle signals, way better than random herb filler for serious lifters.
- 200 mg L-leucine is the top amino for kicking off muscle building via mTOR. This dose isn't huge like the 2.5-5 g in studies, so think of it as a solid backup, not the main driver.
- BioPerine® helps everything absorb better in these capsules, where you want every bit to count. It's the go-to black pepper extract for boosting uptake.
- 1,500 mcg RAE vitamin A isn't just filler. It supports immune health and tissue repair, which really matter when you're pushing recovery to make gains stick.
- Full label with no prop blends. In a world of shady anabolic mixes, this shows exactly what's in it and how much, so you know what you're getting.
- No stims on purpose. Add this for growth support without jacking up your caffeine, heart rate, or messing with sleep in a stacked routine.
Who Is This For?
- Bodybuilders bulking who have protein and creatine locked, wanting extra stim-free muscle backup. Ajuga, HICA, and epicatechin green tea help recovery, lean gains, and flow over buzz.
- Intermediate folks on high-volume splits feeling wrecked by day three or four. This aids muscle hold and bounce-back without more caffeine in the mix.
- Evening lifters who can't do late stims. Stim-free means it fits growth plans without killing sleep like caffeine bombs.
- Cutters holding lean while dropping fat. HICA's protection and anabolic angle beat plain energy supps here.
- Capsule fans over more powders. Simple way to add targeted help without mixing or gut drama.
- Ajuga and turkesterone curious types wanting clear labels, not hidden blends. Full info lets you see and decide.
How to Use
Hit 4 capsules daily—that's the full serving for this 120-cap bottle. It's for ongoing muscle help, not stim timing, so steady use beats perfect minutes. Take with a meal for better comfort and routine. Training days, 30-60 pre if it fits, but no energy or pump rush expected. No need to ease in for stims, but if you're sensitive, start with 2 caps a few days then go full. Stacks well with creatine, whey, and a pre for quick boosts. No cycling like stim stuff—test it over weeks straight. Keep it cool and dry, lid tight. If on meds, check with your doc since BioPerine® can tweak absorption.
What to Expect
First 0-30 minutes, not much to feel if you're used to pres, since no stims mean no rush. Early days are about easy adding in without crashes or sleep issues. Week 1 is getting consistent—this is support, not fireworks. By weeks 2-4, check your log: recovery might smooth out, tough workouts cost less, and holding lean mass gets easier in hard phases. Judge it on full weeks, not one session. It's about feeling more bulletproof under volume—that's when it shines.

Frequently Asked Questions
What is the serving size for 5% Nutrition Bigger by the Day?
The verified current formula uses a serving size of 4 capsules, with 30 servings per 120-capsule bottle. That full serving provides 1,000 mg Ajuga extract, 500 mg HICA, 300 mg green tea extract standardized for epicatechin, 200 mg L-leucine, vitamin A, and BioPerine®.
Does Bigger by the Day contain caffeine or stimulants?
No. This is a stim-free formula, so it is not designed to deliver an energy rush, appetite suppression, or a classic pre-workout feel. Its role is daily muscle-support and recovery support, not acute stimulation.
What is the main ingredient in Bigger by the Day?
Ajuga whole herb extract at 1,000 mg is the headline ingredient. In this category, Ajuga turkestanica is used primarily as a source associated with turkesterone-style anabolic support, though the human evidence is still emerging rather than definitive.
Is the leucine dose in this formula clinically dosed?
Not as a standalone leucine supplement. The formula contains 200 mg L-leucine, while research-backed standalone leucine dosing is generally 2,500-5,000 mg to strongly activate mTOR and muscle protein synthesis. Here, leucine functions more as a supportive inclusion than the formula’s primary anabolic driver.
How long does Bigger by the Day take to work?
This is not a product you judge by a single workout. Because it is stim-free and aimed at cumulative support, most users should assess it over 2-4 weeks of consistent daily use, paying attention to recovery quality, training resilience, and lean-mass retention.
Can I stack Bigger by the Day with creatine and protein?
Yes, and that is one of the best ways to use it. Creatine monohydrate supports phosphocreatine replenishment and strength performance, protein provides the raw material for muscle repair, and Bigger by the Day adds a separate recovery/anabolic-support layer through Ajuga, HICA, epicatechin, and BioPerine®.
Should I take Bigger by the Day before workouts or every day?
Every day is the smarter approach. Since there are no stimulants and no immediate performance ingredients driving a short-term effect, consistency matters more than exact pre-workout timing.
Is this product fully disclosed or proprietary?
It is fully disclosed. That is a real advantage in the natural anabolic category, where many products hide behind proprietary blends that make it impossible to judge ingredient relevance or dose quality.
What does HICA do in this formula?
HICA is a leucine metabolite included at 500 mg for anti-catabolic and recovery support. It is there to help address muscle breakdown and training wear-and-tear, making the formula more complete than an Ajuga-only product.
Can I use Bigger by the Day on a cut?
Yes, that is one of its more logical use cases. The formula is designed to support lean-mass retention and recovery without adding stimulants, which makes it attractive during calorie deficits when preserving muscle becomes harder.
