MuscleTech’s Peptide Series has quickly grown into a strong series built around targeted, research-backed applications. The collection currently includes Muscle Peptide 185, Creatine Peptide 447, and Recovery Peptide 144, each approaching performance from a narrow, peptide-driven angle. The brand has recently revealed a few extensions in the pump-powering Nitric Oxide Peptide 160 and testosterone boosting Test Peptide T10, and rounding out the next expansion of the line is Metabolic Peptide 320.
The upcoming Metabolic Peptide 320 from MuscleTech centers on TheoLim at 450mg, a branded lime peel and cocoa seed extract combination studied for metabolic activation and calorie expenditure. Further supporting its core goal is 250mg of DNF-10 yeast hydrolysate peptide, designed to stimulate natural GLP-1 release. Together, they target energy utilization, appetite signaling, and increased resting calorie burn without the intense stimulants you get in your standard weight loss supplement.

The clean, simple, and premium formula of Metabolic Peptide 320 aligns perfectly with the other five entries in MuscleTech’s Peptide Series. You get two quality and proven ingredients in TheoLim and DNF-10, all without any stimulants or any common crossover with other products, meaning you can seamlessly add this to your daily supplement stack even if you’re already taking another fat burner.
MuscleTech Metabolic Peptide 320 is the third and final extension to the Peptide Series, which, similar to Nitric Oxide Peptide 160, puts the line into a whole new category that isn’t as immediately related as the others. It really shows the brand is looking to take the Peptide Series concept beyond its original muscle-building, performance realm. Metabolic Peptide will be arriving soon, alongside the other two Peptide Series entries, Nitric Oxide Peptide 160 and the TestFactor-powered Test Peptide T10.
