Maximum Human Performance Probolic-SR is a chocolate sustained-release protein powder designed to support muscle building and recovery, with a 2 lb (0.91 kg) blend of whey, soy, and casein.
Protein needs can arise around training, between meals, and during the overnight period. Probolic-SR combines protein sources with different digestion rates and a sustained-release coating for people looking for a protein powder intended to provide amino acids over time. Its purpose is to support muscle building and recovery and help reduce muscle breakdown as part of a nutrition routine.
Probolic-SR combines fast-digesting whey, intermediate-digesting soy, and slow-digesting casein with an exclusive micro-coating technology. The coating is designed to extend the amino acid supply beyond 6 hours, while the differing digestion rates of the three protein sources contribute to a multi-phase release profile. This makes the formula suitable for people who want protein support that extends beyond the short release associated with whey alone.
Probolic-SR provides glutamine, arginine, and the branched-chain amino acids leucine, isoleucine, and valine, along with all essential amino acids. These amino acids are included to support muscle building and recovery. The formula is designed to supply amino acids around periods when training and recovery are part of the routine, rather than relying on a single protein source.
Probolic-SR is designed for use before or after workouts, between meals, or at nighttime. Before training, its protein blend provides amino acids as part of a pre-workout nutrition routine. After training, the combination of fast- and slower-digesting sources is intended to support recovery over an extended period. Between meals or before sleep, its sustained-release design offers another way to include protein when a longer amino acid supply is the goal.
Chocolate Probolic-SR suits people seeking a multi-source protein powder for training days, between-meal nutrition, or nighttime use. It is a protein supplement designed to support muscle building and recovery, not a substitute for an overall nutrition plan. Its whey, soy, and casein blend with sustained-release micro-coating makes it a fit for buyers looking for protein designed to supply amino acids over time.
