Figure 3. Illustrative. Assessed outcomes plotted on a common standardised axis so that direction and relative magnitude can be compared at a glance. The estimates are not on a common natural scale and the intervals are the Institute's standardised representation of the reported precision, not the published confidence intervals. Published intervals appear in the per-indication extracts and in the text below.

§3.1Growth hormone deficiency and growth-hormone secretagogue pharmacology

Anchor outcome. Peak stimulated growth hormone.

Effect as recorded. Mean IGF-1 increased 1.5- to 3.0-fold above baseline and remained elevated for 6 to 11 days after a single dose in a phase 1 study of 11 participants; phase 1, n = 11; no confidence limits reported for the primary pharmacodynamic outcome.[1,2]

Certainty. Low certainty A genuine phase 1 pharmacodynamic result exists and the Institute reports it. It establishes that the compound raises IGF-1 in humans. It does not establish any clinical outcome.

Contributing trials. CJC-PH1-ASCENDING · CJC-PH1-MULTIDOSE. Full structured abstracts are published for each.

§3.2Biological ageing and healthspan endpoints

Anchor outcome. Epigenetic age acceleration.

Effect as recorded. No randomised human evidence identified; —.[2,3]

Certainty. Very low certainty No trial supports any ageing or healthspan claim.

Contributing trials. None identified. The rating reflects an absence of controlled evidence rather than conflicting evidence.

§3.3Sarcopenia and lean-mass preservation during weight reduction

Anchor outcome. Change in appendicular lean mass by DXA.

Effect as recorded. No randomised human evidence identified; —.[3,4]

Certainty. Very low certainty Body-composition claims rest on mechanistic reasoning, not on trial evidence.

Contributing trials. None identified. The rating reflects an absence of controlled evidence rather than conflicting evidence.
