CJC-1295 No DAC Animal vs Human Research: Data Comparison
Peak GH elevation timing 15–30 minutes post-injection 60–90 minutes post-injection Animal data underestimates human absorption lag by 200–300% Duration of elevated GH 4–6 hours 2–3 hours before somatostatin suppression Feedback inhibition acts more aggressivel
This comparison does not assign a generated winner or score.
- Peak GH elevation timing
- 15–30 minutes post-injection
- 60–90 minutes post-injection
- Animal data underestimates human absorption lag by 200–300%
- Duration of elevated GH
- 4–6 hours
- 2–3 hours before somatostatin suppression
- Feedback inhibition acts more aggressively in humans
- Dose-response linearity
- Near-linear up to 10× therapeutic dose
- Diminishing returns above 100mcg/dose
- Receptor saturation ceiling appears earlier in human pituitary
- Pharmacokinetic half-life
- 30–45 minutes
- 6–8 days
- 200-fold difference fundamentally changes dosing frequency
- Hepatic first-pass metabolism
- Minimal. Renal clearance dominant
- Significant. CYP3A4 and DPP-4 degradation
- Human liver enzymes absent in rodent models alter bioavailability
- Adverse event incidence
- <5% at therapeutic doses
- 15–25% injection site reactions, 10–15% water retention
- Human trials reveal side effects invisible in animal toxicology
