From Julian Mercer

evidence

What adult sermorelin studies establish

There is adult research. Its specific populations and endpoints deserve a more careful reading than broad anti-aging claims.

Julian Mercer

testing

IGF-1 results: why age and clinical context matter

One laboratory number cannot establish the need for a growth-hormone-related treatment.

Julian Mercer

comparisons

Sermorelin versus tesamorelin: different products, different evidence

Sharing a pathway does not make two treatments interchangeable.

Julian Mercer

sleep

Sleep claims and growth-hormone secretagogues

A physiological relationship with sleep does not establish a treatment for insomnia.

Julian Mercer

body-composition

Lean mass and fat mass: read the actual endpoint

A change on a scan is not automatically stronger muscles, better function or meaningful weight loss.

Julian Mercer

safety

Adverse events and monitoring: what published research can tell you

A reassuring mechanism is not a replacement for product-specific evidence and a clear follow-up plan.

Julian Mercer

physiology

GHRH, sermorelin and growth hormone: understand the pathway

Stimulating a signal and supplying a hormone are different interventions.

Julian Mercer

regulation

Historical GEREF approval and today’s compounded sermorelin

A regulatory history can be accurate while still being misleadingly applied to a current product.
