- The table below compares baseline lab values, expected changes during active MT-2 administration, and post-administration recovery patterns across the six core monitoring categories.
- ALT (Liver Enzyme)
- 7–56 U/L
- Mild elevation (10–20% increase) in 30% of subjects
- Returns to baseline within 4–6 weeks of cessation
- Weeks 0, 4, 8, 12
- Elevation suggests increased hepatic oxidative load from melanin synthesis. Not direct toxicity. Persistent elevation above 80 U/L warrants dose reduction or protocol halt.
- Cortisol (Morning)
- 6–23 mcg/dL
- Reduction of 15–30% in subjects with high-normal baseline cortisol
- Gradual return over 6–8 weeks post-cessation
- Weeks 0, 4, 8
- MC2R-mediated ACTH suppression reduces cortisol production. Levels below 5 mcg/dL indicate clinically significant adrenal suppression requiring protocol termination.
- Prolactin
- 4–15 ng/mL (male), 4–23 ng/mL (female)
- Elevation to 20–35 ng/mL in 18–25% of subjects
- Returns to baseline within 3–4 weeks of cessation
- MC4R activation in hypothalamus drives prolactin secretion. Levels above 40 ng/mL may cause gynecomastia (males) or menstrual irregularities (females).
- Fasting Glucose
- 70–99 mg/dL
- Mild reduction (5–10 mg/dL decrease) due to appetite suppression and improved insulin sensitivity
- Baseline restoration within 2–3 weeks
- Weeks 0, 8
- MC4R-mediated appetite suppression reduces caloric intake. Monitor for reactive hypoglycemia if glucose drops below 65 mg/dL.
- Creatinine
- 0.7–1.3 mg/dL
- No significant change in subjects with normal baseline renal function
- Stable
- Weeks 0, 12
- Peptide metabolites are renally cleared. Elevation suggests impaired clearance. Not peptide nephrotoxicity.
- ACTH
- 10–60 pg/mL
- Suppression to 5–15 pg/mL in subjects with baseline ACTH above 30 pg/mL
- Returns to baseline within 8–12 weeks post-cessation
- Direct marker of melanocortin receptor activation impact on pituitary-adrenal axis. Suppression below 5 pg/mL indicates over-activation requiring protocol adjustment.
