Here's The Science on How Peptides Could Boost Your Workout

Peptides are short amino-acid chains that are more easily absorbed than whole collagen protein.

Whey-derived peptides tend to increase muscle size more than collagen in a 10-week trial, while both can yield similar strength gains.

Collagen peptides combined with vitamin C showed improved explosive power and may support tendons and cartilage.

Studies report that 15 g collagen with vitamin C before exercise and 20 g daily can aid collagen production and reduce soreness, but trials are often small.

Product variability and source contamination are concerns for applying results broadly.
