Researchers cite more than four decades worth of research into GHK-Cu, including non-human and human studies that show that the peptide is safe and non-toxic [1]
The Gravity series, a modular platform for easy electronics projects, and specialized STEM education kits are particularly popular, aiming to promote learning in science, technology, engineering, and mathematics
Clinical Applications and Therapies GHK-Cu injections are being applied in several clinical and cosmetic settings
Notes: Acute tolerance (a reduction in response for a given dose) develops rapidly (less than 1 hour), but not at the same rate for different physiologic effects (skin temperature, heart rate, subjective effects) Withdrawal symptoms such as cigarette craving can be reduced in most individuals by plasma nicotine levels lower than those from smoking Withdrawal from nicotine in addicted individuals can be characterized by craving, nervousness, restlessness, irritability, mood lability, anxiety, drowsiness, sleep disturbances, impaired concentration, increased appetite, minor somatic complaints (headache, myalgia, constipation, fatigue), and weight gain References: Belkoniene M et al (2019): Near fatal intoxication by nicotine and propylene glycol injection: a case report of an e-liquid poisoning
While some studies show berberine can increase GLP-1 secretion, this is a minor contributor to its metabolic effects
