In the withdrawal trial, continuing preserved loss far better than switching to placebo, which regained about 14% over a year. The metabolic benefit fades in proportion to the weight regained, so a taper plus protein and resistance training beats a hard stop
My protocol during this period: Retatrutide: 2mg weekly subcutaneous injection (ramped to 4mg by week 10) GHK-Cu: 1mg daily subcutaneous, rotated injection sites Cycle length: 12 weeks on, 4 weeks off Training: 4 days resistance training per week, 8,000 to 10,000 steps daily Protein intake: 130g daily minimum I sourced both from Red Fox Peptides
Retatrutide appears to influence both: Energy intake Energy output This dual-direction modulation is why it is often regarded in research circles as the best peptide for fat loss, particularly where body composition preservation is a priority
