I had severe fatigue due to MAC in December 2022. I cant work at all and felt my legs weak in that month. I started peptide therapy in March 2023 and it helps with my fatigue and energy a lot. I heard peptide helps with cancer and auto immune disease. For normal person without autoimmune diseases like me, I just take it with my antibiotics treatment to reduce toxicity from antibiotics. I am taking three medication + inhaled amikacin.
