Build Stronger Muscles Faster on Rest Day
Creatine and beta-alanine are top ergogenics that produce the greatest athletic performance enhancements when taken every day, including rest day. This regimen presents challenges:
- Intense training depletes beta alanine and creatine from muscle tissues
- Higher daily dosing may be linked to uncomfortable tingling and bloating
- Stacking, dosing and timing of several supplements can be hard to master
SPORT Maintain solves these muscle loading challenges on rest day with creatine and beta-alanine innovations – easy to take and stacked to perform.
Creapure® pH10 Creatine, 3000 mg
SPORT Maintain Creapure® pH10 replenishes creatine muscle stores on rest days. Consistent daily supplementation is the best way to unlock creatine’s full ergogenic benefits, including:
- Raising muscle ATP energy to power growth while recharging muscle for your next session;
- Stimulating synthesis of proteins, stem cells and growth factor used to build muscle;
- Modulating the oxidative stress and myostatin that can limit muscle repair and growth
SPORT Maintain maximizes all of these creatine benefits by keeping levels elevated in muscle tissues, supporting growth and repair while charging you up for your next high-intensity session.
SPORT Maintain Creapure® pH10 is a quality 99.5% pure form of pH-balanced creatine monohydrate that enhances bioavailability while reducing creatine bloating and gastric distress.
SR Carnosyn® Beta-Alanine, 1600 mg
SR CarnoSyn® is advanced Beta-Alanine: An overall pre- and post-workout muscle booster that works by raising muscle carnosine.
Consistent muscle carnosine loading is one of the most important sports nutrition practices because it supports both muscle recovery and subsequent muscle performance:
SR CarnoSyn® muscle recovery support
- Antioxidant activity to neutralize exercise-induced, muscle-damaging free radicals;
- Inhibits protein-damaging advanced glycation end-products (AGEs);
- Acts as a muscle-alkalizing pH regulator, buffering impact of muscle-damaging acids.
SR CarnoSyn® muscle performance support
- Increases the working capacity of muscle across all strength and endurance activities;
- Delays muscle failure by reducing acidosis and boosting muscle buffering capacity;
- Boosts overall muscle strength and endurance.
SPORT Maintain SR CarnoSyn® is innovative sustained-release (SR) Beta-Alanine that gradually raises and maintains muscle carnosine for 12 hours of steady anabolic nourishment on rest day. SR CarnoSyn® remains in the body longer for peak loading and higher dosing without Beta-Alanine tingling discomfort.
SPORT Maintain stacks optimally with SPORT Pre and SPORT Post
Combined, they supply a 2-day total of 3.6 g Creatine (as Creapure® pH10) and 6 g Beta Alanine (as CarnoSyn® and CarnoSyn® SR). SPORT Maintain, SPORT Pre and SPORT Post are your convenient solution for getting the consistent daily beta alanine + creatine intake shown to produce the best muscle benefits in human research.
NutriGenesis® Iron, 2.5 mg
The harder you train, the more you need iron: Exercise reduces iron absorption while accelerating iron loss through sweat. Low iron limits red blood cells’ oxygen transport ability – potentially leading to reduced exercise capacity, fatigue and sub-par overall physical performance.
- Researchers have suggested that iron supplementation helps improve performance across athletic strength, endurance and maximal muscle power output.
SPORT Maintain NutriGenesis® iron is complexed with a matrix of absorption-enhancing cofactors – making it easy for athletes to restore and sustain ideal iron levels required for peak performance.

Maintain + Post
SPORT Post is taken immediately after exercise to restore muscles. SPORT Maintain picks up where SPORT Post leaves off, steadily nourishing muscle growth over 12 hours on rest day. Take SPORT Maintain + SPORT Post for a combined 2.4 g Beta Alanine and 4.25 g Creatine that feeds and restores muscle from the moment you finish your session through rest day.
Maintain + Pre
SPORT Pre is taken 30 minutes before exercise to quickly supercharge muscles with ergogenic nutrition. SPORT Pre’s performance-enhancing effects are amplified after SPORT Maintain nourishes muscles on rest day. Take SPORT Pre + SPORT Maintain as complementary formulas that work as a team to develop and prime muscles for superior performance.
