Transcript
Hexarelin | Hormone-response research
Hexarelin is a synthetic growth-hormone-releasing peptide. Human experiments ask how hormone levels respond, which is a different question from whether a person becomes healthier or stronger. [1]
HUMAN STUDY | Growth-hormone release
A double-blind, placebo-controlled study found that Hexarelin stimulated growth-hormone release in healthy volunteers. The researchers measured an endocrine response, not lasting muscle gains. [1]
More than one hormone can respond
Other human research also examined effects on prolactin, ACTH and cortisol. This reminds us that hormonal interventions can involve more than one signalling system. [2]
Clinical claims need clinical outcomes
Short-term hormone measurements do not settle long-term benefit or safety. Claims about recovery, body composition or anti-aging need trials designed to measure those outcomes directly. [1] [2]
