Pre-treatment: Measure morning resting heart rate for 5 days Calculate average baseline Record any existing caffeine or stimulant use During treatment: Measure resting heart rate 3 times weekly during dose escalation Continue at each dose for minimum 4 weeks before increasing If resting HR exceeds baseline by more than 15 BPM, hold dose for an additional 2 weeks If resting HR exceeds 100 BPM at rest on two or more measurements, consult physician Expected timeline: Weeks 1-8: minimal heart rate change at starting doses Weeks 8-24: gradual increase of 5-10 BPM at therapeutic doses Weeks 24+: stabilization and gradual decline toward baseline This is the approach most researchers follow successfully, and it aligns with the standard retatrutide dosing protocol used in clinical trials
Haemoglobin levels begin to rise after about one week, whilst the mean corpuscular volume (MCV), which is typically elevated in B12 deficiency, gradually normalises
