Growth Hormone
Ipamorelin
Nearly always taken alongside CJC-1295 to raise the body's own growth hormone. The appeal is that it's 'cleaner' than older versions, less likely to spike appetite or other hormones. Human trials for this exact use are still thin, though.
Growth-hormone with direct human PK/PD evidence, but limited evidence for meaningful wellness or body-composition outcomes.
How well studied
Tier Guide: A = Well studied, B = Some good studies, C = Early evidence & D = Barely studied
Tested in people, but in smaller or fewer studies. A decent picture, just less certain.
UK status
How you could legitimately come across it here, if at all
No authorised UK medicine contains this, and we have no record of a routine UK clinic route. Material sold online is unregulated.
Evidence strength and UK regulatory status answer different questions.
Overview
How it works
Targets one specific hormone switch to trigger growth hormone release, leaving the appetite and stress-hormone switches alone, unlike older versions.
Selectively stimulates the to trigger GH release, without meaningfully raising cortisol or appetite.
Reported benefits
- Human volunteer studies show dose-related growth-hormone release
- Clinical benefits for recovery, sleep, muscle gain or fat loss are not established

Getting it in the UK
No authorised UK medicine contains this, and we have no record of a routine UK clinic route. Material sold online is unregulated.
Where it turns up
- Not routinely available in the UK
- Unregulated online market
No authorised UK medicinal product containing ipamorelin was identified in this audit. EviTide does not treat online or clinic marketing as proof of a lawful UK supply route.
Not MHRA-licensed; prescribable by a private UK doctor via the unlicensed-medicines route
MHRA: the UK regulator that assesses whether a medicine is safe and works before it can be authorised for use here. Something not being MHRA-licensed does not automatically mean it is illegal, and it does not mean it is safe.
This is background information about UK regulation, not advice about what you can or should obtain.
