MuscleTech has officially formed its latest trio of advanced supplements under the Peptide Series banner, consisting of Muscle Peptide 185 (originally Peptide 185), Creatine Peptide 447, and Recovery Peptide 144. Each product is built around a patented peptide compound and designed for a specific phase of the training. Muscle Peptide 185 targets protein synthesis, Creatine Peptide 447 supports performance and strength, and Recovery Peptide 144 accelerates recovery and reduces breakdown.
Stacking the full Peptide Series delivers benefits across all aspects of the muscle-building cycle, from anabolic activation to post-workout repair, and it is something MuscleTech promotes. Muscle Peptide 185 uses 2g of DL-185 dileucine to stimulate muscle protein synthesis more effectively than standard leucine. You then have Creatine Peptide 447 with 6g of creatine power split between PepForm Creatine Peptides and monohydrate, supporting strength and power output, and Recovery Peptide 144 finishes the stack with 2.4g of PeptiStrong and myHMB for reducing muscle breakdown and inflammation.

The synergy of the three-piece Peptide Series brings back memories of MuscleTech’s past high-impact stacks like the Creakic, Leukic, and Gakic, as well as Clear Muscle, Plasma Muscle, and Phospha Muscle trio. Much like those lines, each product here plays a specific role and works even better when combined, targeting growth, performance, and recovery. Taken together, the stack is a comprehensive set, and we imagine there will be a bundle with them all at muscletech.com when they’re all live.
