Comparison

Tesamorelin vs CJC-1295 DAC

Two long-ish GHRH-axis options: the approved drug with outcome data versus the week-long research analog.

Summary

Tesamorelin is FDA-approved with randomized visceral-fat trials behind a defined daily schedule; CJC-1295 DAC offers weekly convenience through albumin binding but has no outcome trials and a non-physiologic elevation pattern.

Key answers

Which has real outcome evidence?

Tesamorelin, decisively: phase 3 randomized trials of visceral-fat reduction in HIV lipodystrophy and FDA approval. CJC-1295 DAC has early human pharmacology studies showing sustained GH and IGF-1 elevation: pharmacology, not outcomes.

How do the pharmacology and schedules differ?

Tesamorelin is daily and pulse-friendly, matching physiologic GHRH signaling. The DAC conjugate binds albumin and extends CJC-1295's half-life to roughly a week, which is convenient but produces sustained rather than pulsatile elevation: the community's pulse-versus-bleed debate.

What is the regulatory picture for each?

Tesamorelin is prescription-only and counterfeited because of cost. CJC-1295 DAC is unapproved, appears in FDA compounding discussions, and is WADA-prohibited like all GH-releasing factors.
