A good number of users find MOTS-c works great until welts show up, or full allergic reactions. NAD+ tends to be safer, oral precursors too, and SS-31 as well.

A low daily Cialis dose, around 5mg, helps somewhat with energy and recovery, and it's cheap, roughly $13 shipped for ninety tablets through a discount pharmacy service. Got mine via a free telehealth visit tied to an online retailer's perk. Carbs and starches helped with tirz fatigue - protein bagels from the grocery store cover both bases. Reta never gave me that exhaustion by comparison, and any sleep trouble cleared up fast. Since you mentioned test plus mast in your intro thread, you might be overdue for a careful look at E2 levels, which raises its own questions.
