Peptide Performance.
No Shots Required.

Engineered to activate growth, fight muscle breakdown, and power high-performance recovery—this is where science meets serious results. The full peptides stack delivers a complete system that works across every phase of your training: from anabolic activation and anti-catabolic defense to cellular energy and repair. When combined, these three advanced formulas go beyond what any single product can do—driving superior strength, faster recovery, and greater overall performance.

How the Full Peptide Stack Delivers

Benefit

Full-Cycle Muscle Support

Activates muscle protein synthesis, preserves muscle tissue post-training, and boosts recovery.

Anabolic Signaling

Supports mTOR pathway activation and primes the body for lean muscle growth.

Anti-Catabolic Defense

Reduces exercise-induced muscle breakdown and supports faster repair.

Power & Performance

Enhances strength output through improved ATP regeneration and cellular energy efficiency.

Recovery Optimization

Supports hydration, reduces inflammation, and accelerates readiness for the next session.

The Science

Formulated With Purpose. Validated by innovation.

muscle peptide 185

¹Subjects taking DL-185™ significantly increased total max strength by 144%, compared to placebo (DL-185™ 154 lbs. vs Placebo 63 lbs.)!

²In a groundbreaking study, subjects who consumed 2000 mg of DL-185™ demonstrated a massive 159% greater activation of muscle protein synthesis compared to baseline and 60% greater than regular leucine.

creatine peptide 447

¹In a 12-week study, test subjects taking 2 servings (6g) of creatine monohydrate gained over 4 times more lean muscle than those on placebo (7.12 lbs vs. 1.30 lbs).

The same study showed creatine users gained 78% more muscle size (1.62 m³ vs. 0.91 m³).

²In a 10-week study, collegiate football players taking 5g of creatine daily saw strength gains 4.2x greater than placebo (11.2 lbs vs. -3.5 lbs).

³In a 10-day study, subjects using the creatine form in Peptide 447 increased bench press strength capacity by 18.6% (6,658 joules vs. 5,613 joules).

recovery peptide 144

¹In a 17-day study, test subjects taking PeptiStrong™ increased power output by 144% 72 hours post-exercise from baseline, compared to the placebo group’s decline.

²In an 8-week study, subjects who consumed PeptiStrong™ with an exercise program experienced 100% more muscle endurance (4 reps vs. 2 reps) and 19% more muscle strength (32 lbs. vs. 27 lbs. on leg extensions) compared to those using a placebo.

³In a study of young adult men aged 19–29 who consumed 3g of HMB per day in combination with 1.5 hours of weight training 3 days per week and a protein-rich diet (1.4g/kg/day), there was a significant reduction in exercise-induced rises in urinary 3-methylhistidine levels, a marker of muscle protein breakdown, during the first 2 weeks of the study compared to control.
