Maximum Human Performance Probolic-SR is a sustained-release protein powder designed to support muscle building and recovery, with 24 g of protein per serving and a micro-coating technology for extended amino acid release.
Probolic-SR is made for people who want protein support at different points in the day, including around training, between meals, and before sleep. Its combination of protein sources and sustained-release coating is intended to provide a longer-lasting supply of amino acids than a fast-digesting protein source alone.
Probolic-SR combines protein sources with different digestion rates and uses a proprietary micro-coating to extend the release profile. Whey is the fast-digesting source, soy is intermediate, and casein is slow-digesting; the coating further extends amino acid availability beyond 6 hours. This multi-phase approach is designed to support a more extended duration of protein synthesis for muscle building and recovery.
Probolic-SR is intended for pre-workout, post-workout, between-meal, and nighttime use. The fast-acting protein source makes it suitable after training, while the longer release profile is designed for times when a more extended amino acid supply is desired, including overnight.
Probolic-SR provides glutamine, arginine, and the branched-chain amino acids leucine, isoleucine, and valine. These are the five critical amino acids highlighted in the formula for muscle-building support. The product is designed to support muscle building, help limit muscle breakdown, and support recovery; individual results are not guaranteed.
Maximum Human Performance Probolic-SR is suited to people seeking a protein powder for training periods, between meals, or nighttime use, with a release profile designed to extend beyond a quick protein source. Its whey, soy, casein, and micro-coating combination is made for sustained protein support throughout the day.
