MuscleTech continues to push the boundaries of sports nutrition innovation with Recovery Peptide 144, completing their groundbreaking Peptide Series that transforms how we approach muscle building and recovery supplementation. Following the massive success of Peptide 185 with dileucine and Creatine Peptide 447 with cognitive-enhancing creatine peptides, Recovery Peptide 144 addresses the critical recovery phase that determines whether your training efforts translate into real muscle growth and strength gains.

Including PeptiStrong: Muscle Protein Synthesis Boosting Peptide

Recovery Peptide 144 includes PeptiStrong™, the world’s first AI-discovered bioactive peptide ingredient. Using artificial intelligence and machine learning algorithms, researchers identified peptides within fava bean protein that activate muscle protein synthesis pathways, reduce exercise-induced muscle damage, and suppress myostatin (the body’s natural muscle growth inhibitor). This is a scientifically engineered formula that targets both the anabolic and anti-catabolic processes essential for optimal muscle adaptation.

The formula combines 2.4g of PeptiStrong with 1.5g of myHMB® (calcium beta-hydroxy-beta-methylbutyrate) with a strategic dose of vitamin D. This combination creates what MuscleTech calls “dual-pathway recovery support”: PeptiStrong activates muscle protein synthesis while suppressing myostatin, while myHMB prevents muscle protein breakdown and accelerates recovery between training sessions.

Why is it Called Recovery Peptide 144?

In controlled studies, subjects taking PeptiStrong showed a 144% increase in strength recovery after exhaustive exercise compared to placebo, while also experiencing 47% less muscle fatigue and 54% better athletic performance recovery over a 72-hour period.^[1] Even more impressive, a 2025 study showed that when combined with resistance training, PeptiStrong supplementation led to significantly greater improvements in leg strength and muscular endurance compared to placebo.^[2]

As the third piece of MuscleTech’s comprehensive peptide system, Recovery Peptide 144 ensures that the anabolic signals from Peptide 185 and the enhanced performance from Creatine Peptide 447 translate into real, measurable gains through accelerated recovery and reduced muscle breakdown.

MuscleTech Recovery Peptide 144 Ingredients

Each 6-gram serving of Recovery Peptide 144 provides the following research-backed ingredients:

• PeptiStrong™ Hydrolyzed Fava Bean (Vicia faba) Protein – 2,400mg

  

  PeptiStrong™ is a revolutionary advancement in sports nutrition ingredient discovery, being the first bioactive peptide ingredient identified through artificial intelligence rather than traditional screening methods.^[3] Developed by Nuritas using their proprietary AI platform called Magnifier, PeptiStrong is a hydrolyzed fava bean protein concentrate standardized for specific bioactive peptides that were computationally predicted to enhance muscle protein synthesis and reduce inflammation.

  The ingredient contains two key characterized peptides that were validated both in vitro and through simulated gastrointestinal digestion studies to confirm their bioavailability.^[4]

  Dual-Pathway Muscle Support

  PeptiStrong brings a unique dual-pathway approach to muscle recovery and growth. Rather than simply providing amino acid building blocks like traditional protein powders, it works through informational signaling mechanisms, specifically activating the mTOR pathway through S6 ribosomal protein phosphorylation while simultaneously suppressing inflammatory cytokines like TNF-α.^[3]

  This targeted approach allows the ingredient to promote muscle protein synthesis while reducing the inflammatory burden that can impair recovery, creating an optimal anabolic environment at relatively low doses compared to traditional protein supplementation.

  Clinical Results: Enhanced Training Adaptations

  The most recent clinical research demonstrates that PeptiStrong works synergistically with resistance training to enhance strength and endurance gains. In a 2025 randomized, double-blind, placebo-controlled trial with 72 healthy adults, subjects who combined resistance training with PeptiStrong supplementation showed significantly greater improvements in leg strength and muscular endurance compared to those doing the same training with placebo.^[2]

  This study demonstrates that PeptiStrong doesn’t just support recovery… it actually enhances the training adaptations from resistance exercise, making each workout more effective for building strength and endurance.

  Superior Recovery and Reduced Fatigue

  Additional clinical research on PeptiStrong demonstrates impressive real-world performance benefits in recovery scenarios. In a randomized, double-blind, placebo-controlled trial with 30 healthy males aged 30-45, subjects taking 2.4g of PeptiStrong daily for 14 days showed significantly improved strength recovery over a 72-hour period following exhaustive exercise.^[1]

  Most importantly, the PeptiStrong group actually exceeded baseline strength levels at 72 hours post-exercise, while the placebo group remained below their starting point. This demonstrated not just recovery, but actual improvement beyond pre-exercise capacity. The treatment group also experienced significantly reduced muscle fatigue over the same 72-hour period, allowing for faster return to peak training capacity.^[1]

  Breakthrough Myostatin Suppression

  Possibly most impressive is PeptiStrong’s effect on myostatin expression, with the treatment group showing significant suppression compared to placebo.^[1] Myostatin is a protein that inhibits muscle growth (essentially your body’s “anabolic thermostat”), making its suppression a valuable outcome for anyone focused on building or maintaining muscle mass.

  This myostatin suppression effect makes PeptiStrong unique among recovery supplements. While most ingredients focus on supporting muscle protein synthesis or reducing breakdown, PeptiStrong actually removes one of the body’s natural brakes on muscle growth.

  One important note about the recovery study: subjects did not take PeptiStrong on the day of testing — just during the 14 days leading up to it. This suggests a persistent or semi-permanent effect from PeptiStrong supplementation, indicating that the ingredient creates lasting improvements in muscle recovery capacity.

  This has been a fascinating ingredient to watch over the past couple of years, and the fact that Canada-based MuscleTech has jumped in with it demonstrates that it’s truly ready for primetime… worldwide!

• myHMB® Calcium Beta-Hydroxy-Beta-Methylbutyrate Monohydrate – 1,500mg

  The inclusion of myHMB® creates a powerful anti-catabolic foundation for Recovery Peptide 144. myHMB is the trademarked calcium salt form of β-hydroxy-β-methylbutyrate (HMB), a metabolite of leucine that serves as a potent anti-catabolic agent.^[5]

  Dual-Pathway Anti-Catabolic Action

  HMB also works through a dual mechanism to enhance muscle protein synthesis while suppressing muscle protein breakdown. Like leucine, HMB activates the mTOR pathway, but importantly, HMB’s activation of mTORC1 is independent of the leucine-sensing pathway, making it mechanistically distinct from its parent amino acid.^[5]

  

  Research demonstrates that HMB supplementation can reduce muscle protein breakdown by up to 57% in humans.^[5] This makes it especially valuable during periods of high training stress when the body’s natural tendency is to break down muscle tissue faster than it can rebuild it.

  Strategic Dosing with Synergistic Support

  While the standard clinical dose of HMB is 3g daily, the 1.5g dose in Recovery Peptide 144 is strategically chosen to work synergistically with PeptiStrong’s muscle protein synthesis activation. This dosing approach also has precedent – the landmark Nissen study that first demonstrated HMB’s effectiveness tested both 1.5g and 3g doses, finding that lean body mass and muscle strength increased in proportion to the administered HMB amount, with the 1.5g dose producing meaningful benefits.^[6]

  More recently, a 2022 study in untrained individuals used 1.5g of HMB (delivered only on training days) as part of a multi-ingredient formula and demonstrated significant improvements in body composition when combined with high-intensity training.^[7] This combination approach allows the anabolic effects of PeptiStrong to work alongside HMB’s anti-catabolic protection, potentially enhancing the effectiveness of both ingredients beyond what either would achieve alone.

  MuscleTech has been a pioneer in HMB technology: they also introduced the world to HMB Free Acid in their Clear Muscle softgel formula. The calcium salt form in Recovery Peptide 144 provides excellent bioavailability and stability, making it ideal for powder formulations.

• Vitamin D (as cholecalciferol) – 12.5mcg (500 IU, 62.5% DV)

  The vitamin D inclusion is helpful for unlocking HMB’s full potential, at least in those who are vitamin D deficient. Research has established that HMB’s effectiveness is actually vitamin D-dependent: supplementation produces the most meaningful strength gains when individuals have adequate vitamin D status (≥30 ng/mL serum 25OH-vitamin D3).^[8] Those with insufficient vitamin D levels experience muscle mass gains without corresponding strength improvements, demonstrating the synergistic relationship between these nutrients.

  

  MuscleTech Creatine Peptide 447 combines 6g total creatine (monohydrate + peptide technology) with L-tyrosine and L-theanine for muscle performance and cognitive support. A complete daily performance enhancer beyond traditional creatine.

  The 12.5mcg (500 IU) dose helps ensure optimal conditions for HMB’s anti-catabolic effects while supporting overall muscle and bone health. Since vitamin D deficiency is common among athletes and active individuals, this inclusion addresses a potential bottleneck that could limit HMB’s effectiveness.

  Additional research confirms this critical relationship across different populations. A 12-month study in older adults demonstrated that HMB plus vitamin D3 supplementation improved functional strength and muscle preservation even in non-exercising individuals, with benefits independent of resistance training.^[9] More recent research in middle-aged women showed that HMB plus vitamin D3 not only maintained muscle mass during sedentary periods but also reduced harmful intramuscular adipose tissue (IMAT) infiltration — effects that were most pronounced in women who achieved vitamin D sufficiency.^[10]

  Overall, a smart combination for a recovery supplement!
