NAD+ vs Sermorelin: What the Research Shows

NAD+ and Sermorelin side by side: what they are, how they are regulated and what is still unknown.

Where the research points

Summary of studies, not a recommendation

Consider NAD+ if…

  • you want a systematic review of the field: for NAD+ supplementation, clinical effectiveness for anti-aging or wellness outcomes remains inconclusive[11]
  • you want to know about intravenous use: the systematic review found no eligible outcomes trials of intravenous or intramuscular NAD+ for anti-aging or wellness[11]
  • you want real-world IV data: in a retrospective pilot of commercial infusions, NAD+ IV was associated with moderate to severe gastrointestinal symptoms, higher heart rate and chest pressure[13]

Consider Sermorelin if…

  • you want human data in growth-hormone-deficient children, though uncontrolled: Mean height velocity rose from 4.1 cm/yr at baseline to 8.0 cm/yr at 6 months and 7.2 cm/yr at 12 months (open-label, no control group).[12]

What they have in common

  • Sermorelin's only FDA record is Geref, listed with marketing status Discontinued[14]
Neither is FDA approved for any use in people. Sermorelin is prohibited in tested sport (WADA). Status labels come from public FDA and WADA records; see the sources below.

  • Labs expect GHRH analogues like CJC-1295 to be hard to find because of tiny urine concentrations; the study reports no detections in routine anti-doping samples.PMID 34665524
