- CJC-1295 (no DAC)Research use onlyOne name, two different compounds. The DAC version has a half-life measured in days; without DAC it is short-acting. Protocols that omit the suffix are ambiguous and should not be followed as written.
- IpamorelinResearch use onlyAlso paired, but the DAC variant’s much longer half-life changes the injection schedule entirely rather than just the dose.
