- The table below compares three validated peptide categories used in metabolic research protocols. Each operates through distinct mechanisms and timelines.
- Growth Hormone Secretagogues (MK 677, CJC-1295)
- Bind to ghrelin receptors (GHSR-1a), stimulate endogenous GH release, increase lipolysis and protein turnover
- 24 hours (MK 677), 6–8 days (CJC-1295 with DAC)
- 7–10 days to peak GH levels, 14–21 days to measurable RMR increase
- Strongest evidence base for sustained metabolic rate elevation. 8–14% RMR increase in controlled trials
- Insulin Sensitizers (Mazdutide, GLP-1/Glucagon Dual Agonists)
- Improve glucose uptake efficiency, reduce insulin resistance, shift substrate utilization toward fat oxidation
- 5–7 days (dual agonists)
- 48–72 hours for glucose handling improvements, 10–14 days for metabolic shift
- Best for researchers studying insulin-resistant metabolic states. Effects compound over weeks
- Mitochondrial Enhancers (Cartalax)
- Activate PGC-1α transcription factor, increase mitochondrial biogenesis and oxidative capacity
- Variable (2–4 hours for acute signaling, weeks for biogenesis)
- 14–21 days for mitochondrial density increases
- Long-term metabolic adaptation. Slower onset but sustained baseline elevation
