- ALT (alanine aminotransferase)
- 10–40 U/L
- Return to baseline ± 10%
- Elevated ALT indicates hepatocellular stress from peptide metabolism
- Discontinue use if >2× baseline; retest in 4 weeks
- AST (aspartate aminotransferase)
- Elevated AST suggests broader hepatic or muscle involvement
- Check CK to rule out rhabdomyolysis; discontinue if persistent
- Alpha-MSH (melanocyte-stimulating hormone)
- 20–80 pg/mL
- Return to baseline ± 15%
- Persistent elevation indicates endogenous melanocortin upregulation
- Avoid future cycles if >30% above baseline at 6 weeks
- ACTH (adrenocorticotropic hormone)
- 10–60 pg/mL
- Return to baseline ± 20%
- Elevated ACTH signals HPA axis activation from melanocortin cross-talk
- Cortisol testing required if ACTH >80 pg/mL post-cycle
- TSH (thyroid-stimulating hormone)
- 0.5–4.5 mIU/L
- Remain within baseline range
- TSH changes indicate melanocortin-thyroid interaction
- Endocrinology consult if TSH <0.4 or >5.0 post-cycle
- CRP (C-reactive protein)
- <1.0 mg/L (optimal)
- No increase from baseline
- Elevated CRP post-cycle suggests inflammatory response to peptide load
- Investigate peptide purity; avoid cycles if CRP >3.0 mg/L
