- Different biological endpoints resolve at different rates—here's the evidence-based timeline for each major MT2 effect.
- Circulating peptide concentration
- 3–4 hours (5 half-lives)
- N/A. Peptide is metabolized
- Drug testing or pharmacokinetic concerns resolve within 24 hours
- Shortest clearance window; irrelevant for most discontinuation goals
- Nausea and GI distress
- 3–4 hours
- 24–72 hours (receptor activity normalized)
- Symptoms resolve rapidly; no taper required
- Fastest symptomatic resolution; immediate discontinuation safe
- Appetite suppression
- 72–96 hours (MC4R upregulation)
- Rebound hunger common; normalizes within 7–10 days
- Expect temporary hyperphagia; not pathological
- Spontaneous erections/libido
- 48–72 hours (central MC receptor normalization)
- Sexual side effects cease quickly
- No residual CNS effects beyond 72 hours
- Pigmentation/tanning
- 2–4 weeks (melanocyte activity + epidermal turnover)
- Tan fades gradually; UV exposure accelerates melanin production even post-MT2
- Longest-lasting visible effect; not reversible on demand
- Surgical washout (anesthesia safety)
- 7–14 days (receptor activity baseline)
- Allows anesthesiologists to eliminate peptide-related cardiovascular variables
- Standard precautionary timeline; not evidence of direct contraindication
- Conception safety washout
- 30 days (women), 14 days (men)
- Conservative timeline due to absence of reproductive toxicity data
- Reflects precautionary principle, not documented risk
