Weight regain after stopping is a documented pattern with all GLP-1 class compounds, and Retatrutide is expected to follow the same pattern
For those who prefer a more convenient dosing schedule, Oana Health offers once-weekly GLP-1 formulations, which have been shown to reduce the risk of non-adherence by 11% compared to daily injections
The slight potential reduction comes from lower peak concentrations, but this is partially offset by higher trough levels providing more consistent appetite suppression
Mild side effects like temporary redness at the injection site or nasal irritation (for sprays) may occur, but these are rare and manageable
Moreover, LC administrated for 2 weeks suppresses atrogin-1 messenger RNA (mRNA) level in suspended rats hindlimb [35], and only 7 days of LC administration downregulates MuRF-1 and atrogin-1 mRNAs reducing muscle wasting in a rat model of cancer cachexia [32]
