Retatrutide has less published data specifically on body composition
More ingredients
For clinics focused on hormone replacement, body composition, and regenerative medicine (like yours), FOXO4-DRI represents an exciting frontier to watchand possibly incorporate into a future-rigorous, research-informed protocol
No clinical trials have evaluated their combined use, and major US guidelines do not recommend lipotropic injections
What the research firmly supports: BPC-157's gut healing, vascular, and neuroprotective mechanisms (strong preclinical evidence) Thymosin Alpha-1's immune modulating and T-cell restorative effects (strong preclinical + clinical evidence in viral disease) TB-500's cardiovascular repair and angiogenic properties (strong preclinical, early human data) What the research does not yet confirm: Randomised controlled trial data specifically in long COVID populations Optimal dosing, sequencing, and duration specifically for PASC Long-term safety data for extended post-viral use This doesn't mean these peptides don't work for long COVID
The best BPC-157 peptide capsules come from suppliers who publish independent, mass-spec-confirmed COAs, state exact mcg dose per capsule (not proprietary blends), and use the acetate salt form
