Would appreciate any input on using Glutathione peptide. I am 67 and have Hashimotos so thinking this may be beneficial to add to my regimen. Trying to find dosing and frequency of doses. Empower has 200mg/ml, 30ml vial. What is shelf life in refrigerator for “preserved” vs “preservative free”? I haven’t done the Glutathione lab test from Discounted Labs yet but when I do, will LabCorp have a reference range so I can adjust dosing to reach an optimum level? I currently subq test cyp 40 mg e3d, and HCG 350iu eod. This is my 1st post as I have always been able to research everything to gain my answers. Thank you for any responses. P.S. Excelmale, Discounted Labs and Empower Pharmacy has forever changed my life.
