What is the NAD+ for? I don’t know your history or goals, but almost think that MOTS-C might be more effective if you are trying to burn fat, especially if you are exercising.
I see no issues researching NAD+/MOTS-C with a GHRH. You can research Tesa/Ipa/CJC first thing in the morning fasted or an hour before bed after fasting 2-3 hours.
I am not a doctor, or your doctor, but I like to have a specific goal and purpose for whatever peptides I am researching, even if I am researching several at the same time. ;). At the moment, I am much more bullish on MOTS-C than on NAD+ as part of an ongoing maintenance stack.
