Cultures were pulse-labeled with 10 M BrdU (a nucleoside analog that competes with thymidine for incorporation into DNA) in DMEM-10% HS for the final 2-h period of 48-h in culture, followed by immunocytochemistry for detection of BrdU using G3G4 anti-BrdU mAb (1:100 dilution) and HRP-conjugated anti-mouse IgG Ab (1:500 dilution)
However, while 16 days of L-citrulline supplementation at a daily dose of 3.4 g significantly increased plasma citrulline, arginine, and nitrite levels, and increased muscle oxygenation during moderate-intensity (70% VO 2 peak) exercise, there were no superior effects on time-to-exhaustion during high-intensity (90% VO 2 peak) exercise
The July 2026 PCAC review will determine whether either peptide is added to the permanent 503A Bulks List
