Additionally, while some may tolerate a high amount of caffeine, many will experience side effects, including hormone changes and sleep disturbance
## Stacking GLP-1 Peptides with NAD+ and Glutathione for Bodybuilding Advanced bodybuilding fat loss protocols increasingly incorporate [NAD+ injections](/guides/nad-injection-benefits-anti-aging-energy-recovery-guide) and [glutathione injections](/guides/glutathione-injection-2400mg-benefits-dosage-guide) alongside GLP-1 peptides: - **NAD+** supports mitochondrial energy production during caloric restriction, enhances recovery from intense muscle building training, and activates sirtuins involved in metabolic health - **Glutathione** protects against exercise-induced oxidative stress, supports liver detoxification during fat mobilization, and enhances [immune function](/guides/glutathione-immune-support-anti-aging-benefits) during demanding bodybuilding prep phases This multi-peptide injection approach addresses fat loss, recovery, and cellular protection simultaneously a more comprehensive strategy than any single bodybuilding peptide
