Common side effects by peptide type Growth hormone peptides Examples : Ipamorelin, CJC-1295, GHRP-2, GHRP-6, Hexarelin Common side effects (usually mild and temporary): Water retention : Frequency: 20-30% of users Severity: Mild Duration: 1-2 weeks (resolves as body adapts) Why: GH increases fluid retention temporarily Management: Reduce sodium, stay hydrated Increased appetite : Frequency: 30-50% with GHRP-6, less with Ipamorelin Severity: Mild to moderate Duration: 1-2 hours post-injection Why: Ghrelin receptor activation (hunger hormone) Management: Time injections strategically Tiredness post-injection : Frequency: 10-20% of users (first week) Severity: Mild Duration: 30-60 minutes after injection Why: Body adjusting to increased GH Management: Resolves within 1-2 weeks Joint discomfort : Frequency: 5-10% of users (rare) Severity: Mild Duration: Temporary with continued use Why: Increased fluid in joints Management: Reduce dose temporarily Numbness/tingling (hands/feet): Frequency: 5% of users (rare) Severity: Mild Duration: Temporary Why: Mild carpal tunnel from water retention Management: Usually resolves, reduce dose if persistent Read our complete Ipamorelin vs CJC-1295 guide
It works by mimicking the natural GHRH peptide 1 , which is produced in the hypothalamus, to stimulate the release of growth hormone (GH) from the pituitary gland
Why the Ipamorelin and Tesamorelin Blend Works: GHRH + GHRP Synergy Heres where the pharmacology gets exciting
Most people see their strongest results during this phase
We further show that HK2 is elevated under pathological conditions including liver ischemia-reperfusion (IR) injury and hepatocellular carcinoma (HCC) via the transcriptional factor HMGA1
