Product Overview

Betancourt Nutrition

Anabolic Protein Blend*

Muscle Serum Container

Does your protein work as hard as you do?

For years whey protein has been king for supporting lean mass and post-exercise recovery.* Protein innovation in the fitness industry has progressed based on one simple premise: "what could be better?" The answer has come in the form of whey isolates and protein blends. Enter MUSCLE SERUM by Betancourt Nutrition®.*

MUSCLE SERUM was created by an exercise physiologist-led, in-house lab and manufacturing team inspired by new, cutting-edge discoveries in protein/amino acid combinations for post-exercise.*

Research suggests that the combination of whey and casein protein is superior to whey alone in supporting lean mass and recovery.*

MUSCLE SERUM supports recovery and gains with a blend of whey, whey isolate, milk, and casein proteins, each with a varying rate of digestion.*

David Johnston

Team Betancourt Athlete

A recent study showed that the combination of whey protein and GABA lead to greater increases in lean mass than Whey protein alone.*

Innovative MUSCLE SERUM combines whey protein with GABA, BCAAs, and enzymes (bromelain and papain) to support lean mass, recovery, and digestion.*

Muscle Serum Includes:

  • RPM Factors™, a high protein colostrum concentrate containing immunoglobulins and growth factors that’s banned substance-free and supports recovery and performance.*
  • 6.5g of BCAAs (2.9g leucine, 1.8g isoleucine, 1.8g valine per serving) to further support the anabolic signaling necessary to promote lean mass and recovery.*
  • The combination of GABA and whey protein for supporting increases in lean mass.*
  • 25g of total protein per serving in a full disclosure blend.
