Hallo Zusammen,
Vitamin C wird ja häufig empfohlen um Cortisol unter Kontrolle zu halten. Cortisol wird auch das Stresshormon genannt und hat im Körper viele wichtige Aufgaben, es wirkt aber auch stark katabol (Muskel abbauend). Allerdings sollte Cortisol unter Kontrolle gehalten werden. Insbesondere beim Absetzen von AAS wenn der Testosteronspiegel sehr niedrig ist, schüttet der Körper vermehrt Cortisol aus insbesondere während einem harten Training. Das ist auch ein Grund warum beim Absetzen das Training verkürzt werden soll ohne aber die Intensität zu reduzieren.
Zurück zum Vitamin C. Vitamin C ist ein Top Cortisol Inhibitor und hilf auch die Muskelreparatur zu verbessern. Beim Absetzen empfehle ich daher morgens 1000mg Vitamin C und weitere 1000mg Vitamin C nach dem Training.
Hier eine Studie die das zeigt:

AIM: Hypothetically, supplementation with the antioxidant vitamins C could alleviate exercise-induced lipid peroxidation. The purpose of this study was to evaluate the effect of vitamin C supplementation on exercise-induced lipid peroxidation, muscle damage and inflammation. METHODS: Sixteen healthy untrained male volunteers participated in a 30-min exercise at 75% Vo2max. Subjects were randomly assigned to one of two groups: 1) placebo and 2) vitamin C (VC: 1 000 mg vitamin C). Blood samples were obtained prior to supplementation (baseline), 2 h after supplementation (immediately pre-exercise), post-exercise, 2 and 24 h after exercise. Plasma levels of VC, total antioxidant capacity (TAC), creatine kinase (CK), malondealdehyde (MDA), total leukocytes, neutrophils, lymphocytes, interleukin-6 (IL-6) and cortisol were measured. RESULTS: Plasma vitamin C concentrations increased significantly in the VC in response to supplementation and exercise (P<0.05). TAC decreased significantly in Placebo group 24 h after exercise compared to pre-exercise (P<0.05). Although MDA levels were similar between groups at baseline, it increased significantly 2 h after exercise only in the Placebo group (P<0.05). CK increased immediately and 2 h after exercise in both groups and 24 h after exercise only in placebo group compared to pre-exercise (P<0.05). Markers of inflammation (total leukocyte counts, neutrophil counts and IL-6) were increased significantly in response to the exercise (P<0.05). In VC group, there was significant increase in lymphocyte counts immediately after exercise compared with pre-exercise (P<0.05). Serum cortisol concentrations significantly declined after supplementation compared with baseline (P<0.05) as well as declined 2 and 24 h after exercise compared with immediately after exercise in VC group (P<0.05). CONCLUSION: VC supplementation prevented endurance exercise-induced lipid peroxidation and muscle damage but had no effect on inflammatory markers.
