Disruption of circadian rhythms disturbs the balance between pro- and anti-inflammatory cytokines, partly through altered immune cell trafficking and dysregulated clock proteins such as REV-ERB/NR1D1 (93).Innate immune cells such as macrophages and NK cells contain functional circadian clocks, with the CLOCK:BMAL1 heterodimer regulating phagocytosis, cytokine production (e.g., IL-1, TNF-), and antimicrobial activity (94)
To maximize efficacy while minimizing side effects, a common dose escalation regimen in metabolic studies is as follows: Weeks 14: 2 mg weekly (to reduce gastrointestinal side effects) Weeks 58: 4 mg weekly Weeks 912: 8 mg weekly Week 13 onward: 12 mg weekly for optimal results Beyond these metabolic effects, retatrutide is paving the way for exciting advances in tissue repair research
Treatment Duration: IV therapy sessions usually last 30 minutes to an hour
Exogenous AAS inhibit endogenous testosterone production, and discontinuation of their use is often associated with a prolonged decrease in testosterone secretion (Kanayama et al., 2015
