100mg Epicatechin and 50mg Laxosterone® for everyday muscle support
Metabolic Nutrition MyoGrow is a daily capsule for muscle growth support, centered on 100mg epicatechin and 50mg Laxosterone® (that's 5a-hydroxy-laxogenin). This isn't a pre-workout or stim product—it's a non-stim stack you take every day to help with serious training phases.
Epicatechin has the best backing here, though the muscle-growth proof is still building. It's a flavanol—think compounds in cocoa—that helps with blood flow and nitric oxide. Broader studies show it supports heart health, fights inflammation, and aids metabolic function. In gym terms, it's talked about for tweaking myostatin and follistatin (proteins that regulate muscle growth) and better nutrient delivery via improved blood vessel function. At 100mg, it's a solid dose that makes it the star, not just window dressing. You won't feel a buzz, but over time, expect fuller pumps when stacked with a pump pre, better muscle feel, and sessions that just click during hypertrophy.
Laxosterone® brings 50mg of 5a-hydroxy-laxogenin, a plant compound hyped as a natural anabolic. It's popular in bodybuilding for recovery, protein synthesis, and leaning out, but human studies are thin. That's real talk—the evidence isn't as strong as creatine or citrulline. The upsi

Key Highlights
- 100mg Epicatechin per serving makes this a legit heavy hitter, not some weak add-on. In the gym world, it's all about better blood flow, nitric oxide, and helping with muscle fullness and training quality.
- 50mg Laxosterone® delivers branded 5a-hydroxy-laxogenin, nailing that natural anabolic angle. Advanced lifters hunt for this stuff, and the branding sets it apart from cheap knockoffs.
- Two main ingredients with full doses listed upfront— you know exactly what you're getting in epicatechin and Laxosterone®, way better than those shady labels in this space.
- Capsules make it super easy to stick with during a growth phase. Pop one daily, pair it with breakfast or your pre-workout, and keep it consistent for weeks.
- Epicatechin draws from solid research on heart and flavanol benefits. Muscle gains data is okay but growing, and its blood flow angle makes it stand out over random 'anabolic' extras.
- No stims here, so it fits anywhere. Stack it with your pre, use it late at night, or run it daily without piling on more caffeine.
- Boron and vitamin D3 are smart picks for muscle building—boron ties into vitamin D and hormone support, while D3 keeps your bones and training strong.
- Black pepper extract boosts absorption, a no-brainer in capsules. It's there to help you get the most out of everything, not just pad the label.

Who Is This For?
- Physique guys in lean bulks or recomps who use creatine, nail protein, and want non-stim muscle help. 100mg epicatechin and 50mg Laxosterone® suit folks chasing training quality and progress over quick energy.
- Intermediate bodybuilders on high-volume programs needing daily support, even rest days. Capsules with no stims fit 8-12 week blocks where consistency beats one-off boosts.
- Late-day trainers avoiding caffeine that kills sleep. Stack it freely, giving muscle support without the crash or bedtime issues from stim-heavy stuff.
- Seasoned supp users hunting epicatechin formulas. 100mg is a real pillar here, great for blood flow, fullness, and next-level gym supps.
- Athletes stacking natural gains with creatine, protein, and workout carbs. MyoGrow adds specialty vibes on top of solid basics.
- Recomp folks wanting muscle aid without stim thermogenics or heavy hormone plays. It's about training support and anabolic setup, not CNS hype.
How to Use
Run MyoGrow daily for cumulative muscle support, not just pre-gym. Bottle directions first—research shows it's often 2 capsules split between meals, even if data here says 1. Take with food for best results, since vitamin D3 likes fat and capsules go down easier. If you're new to this level, start low and see how you feel. No need to time it with workouts—mornings or later work. Stack with creatine, protein, and maybe a pre or pump if you want. It's an add-on, not a basics replacement. Many cycle 8-12 weeks then break, fitting the Laxosterone® angle. Keep it cool and dry, sealed from heat and moisture.
What to Expect
First 0-30 minutes: probably zilch, no stims and capsules are for daily wins, not instant feels. 1-4 hours: still no big kick, but easy to fit into meals. Days 1-7: mostly mindset—you're adding real muscle support without more caffeine. Weeks 2-4: start noticing better session quality, fuller muscles, and hypertrophy that flows, especially with creatine and carbs. Weeks 4-8: check the mirror, steady performance, and how it backs your growth phase. Don't expect pre-workout vibes—that's not what this is.

Frequently Asked Questions
What are the main active ingredients in Metabolic Nutrition MyoGrow?
The two fully disclosed lead ingredients are epicatechin at 100mg and Laxosterone® (5a-hydroxy-laxogenin) at 50mg per serving. It also contains a 285mg proprietary Anabolic Optimization Matrix with D-Aspartic Acid, boron, vitamin D3, and black pepper extract, but the individual amounts of those ingredients are not disclosed.
Is MyoGrow a pre-workout?
No. MyoGrow is a daily muscle-support capsule, not a pre-workout and not a stimulant product. You do not take it for an immediate rush; you take it consistently to support a growth-focused training phase over time.
Does MyoGrow contain caffeine or stimulants?
No caffeine is listed in the formula, and the product is best understood as stim-free. That makes it easy to stack with coffee, a pump formula, or a standard pre-workout if you want acute workout energy separately.
How strong is the epicatechin dose in MyoGrow?
At 100mg, epicatechin is meaningfully dosed for an advanced physique-support formula. The evidence base for epicatechin in muscle growth is still moderate rather than definitive, but this is not a pixie-dusted amount.
Is the D-Aspartic Acid in MyoGrow fully dosed?
That cannot be confirmed because D-Aspartic Acid is hidden inside a 285mg proprietary blend with boron, vitamin D3, and black pepper extract. Since standalone D-Aspartic Acid is usually discussed in gram-level amounts, this blend structure makes it unlikely that DAA is present at a classic standalone dose.
How should I take MyoGrow?
Use it daily rather than only on training days, ideally with meals for convenience and tolerance. Product research indicates retailer directions commonly suggest splitting capsules across two meals, so check your current bottle for the exact serving protocol.
What should I stack with MyoGrow for better results?
Creatine monohydrate, adequate protein intake, and a quality pre-workout or pump formula are the most logical additions. MyoGrow is a specialty support product, so it works best when the fundamentals of muscle gain are already in place.
How long does MyoGrow take to work?
This is not a same-day sensation product. Most users should evaluate it over 2-4 weeks of consistent use, with the best judgment coming from training quality, muscle fullness, recovery feel, and progress across an entire hypertrophy block.
Is MyoGrow fully transparent?
Partially. The formula clearly discloses epicatechin at 100mg and Laxosterone® at 50mg, but the Anabolic Optimization Matrix is proprietary, so the individual doses of D-Aspartic Acid, boron, vitamin D3, and black pepper extract are not listed.
Does MyoGrow contain any ingredients some users may want to avoid?
Yes. The inactive ingredients include gelatin, titanium dioxide, FD&C Blue #1, and FD&C Red #3. Users seeking vegan capsules or cleaner excipient panels should take that into account before purchasing.
