Ask what the headline is leaving out.
When an offer mentions energy, sleep or body shape, choose the result you care about and ask for the evidence for that result. Keep the question small enough to answer.
Ask what was given, who received it, and how change was measured. Then ask whether the claim rests on a study of sermorelin itself or on a related hormone.
Evidence note
What the sleep studies found
In sleep-lab studies, a hormone given through a vein led to more deep sleep in young men and fewer awakenings in older adults, who had a smaller overall sleep benefit.
The sleep changes also depended on when the hormone was given.
The published study summaries did not say whether they used sermorelin, which copies part of that hormone, or the whole natural hormone.
In a separate 16-week study in older adults, a chemically changed version of sermorelin did not change how well people said they slept.
These studies do not tell you that sermorelin would improve your sleep.
Read the study that measured sleep qualityKeep a claim and its evidence on the same page.
- What exact change is being claimed?
- Which paper is the claim based on?
- Does the paper use the same substance and way of giving it?
- What did the study fail to show or leave unmeasured?
Claim, study and limit:
Ask what is based on studies and what is judgement.
Ask the person treating you which parts of the plan are based on studies and which parts depend on their judgement. Both parts belong in the discussion. If an answer relies on experience rather than a study, ask for that distinction to be made clear.
Leave room for uncertainty. An unknown is worth recording, even when it does not settle the decision.
