Puffiness and fluid retention in the hands and feet, joint aches, wrist tingling (carpal tunnel), and blood sugar creeping up over weeks — most pronounced with MK-677 and somatropin.
These accumulate rather than strike suddenly — reassess and stop rather than pushing the dose up. Check glucose if you can.
A severe persistent headache with vision changes (possible raised intracranial pressure), or symptoms of very high blood sugar — extreme thirst, confusion, vomiting — warrant urgent care.
Allergic reaction: hives, swelling of the lips, tongue or throat, wheezing or dizziness can escalate to anaphylaxis within minutes — call 911 immediately. Site infection: spreading redness, heat, swelling, pus or fever is not wait-and-see; an abscess or cellulitis can need drainage or IV antibiotics. Unverified product: grey-market vials are frequently mislabelled or contaminated, so a reaction may be to endotoxin or the wrong contents, not the named compound.
A methylated GHRP-6 analog with higher potency. Distinctive for secondary binding at CD36, a scavenger receptor expressed in cardiac tissue, which has driven separate investigation into cardiovascular effects independent of GH release. Marked tachyphylaxis — GH response attenuates with continued exposure.
Studied in early human work for GH release and in preclinical cardiac models. No approved indication; efficacy unestablished.
Not FDA-approved. Prohibited in sport (WADA S2).
Desensitisation with repeated exposure. Cortisol/prolactin effects. Long-term safety uncharacterised.
No established human therapeutic dose; early studies characterised GH release and its rapid desensitisation.
Reported from clinical trials or FDA labelling as a matter of record. It is not a recommendation, and for unapproved compounds no dose has been shown safe or effective in humans.
Above is what was administered in trials or on FDA labels, reported as fact. We do not convert it into a personal protocol, calculate a dose for your body weight, or tell you what to inject or how to reconstitute it — that decision belongs with a licensed physician. See our editorial policy.
