People with stomach issues might do better with sublingual or injectable forms
Let's be perfectly clearfor GHK-Cu, the industry and scientific standard is Bacteriostatic Water
Standard dosing protocol: Dose: 250-500mcg per injection Frequency: Twice daily (morning and evening) Duration: 4-8 weeks depending on injury severity Injection site: As close to injury as safely possible Weight-based dosing: Some people dose by body weight: 2.5-4 mcg per kilogram
Maybe it is a torn rotator cuff that wont heal, a knee that screams when you squat, or a tendonitis flare-up that has turned chronic
The evidence base consists primarily of animal studies with limited human clinical data
But for those with greater needs, including adults over 50, vegans, or people with absorption issues, 500 to 1,000 micrograms is common and well-tolerated. King says its also important to note that third-party tested products (for example, those that are USP, NSF, or ConsumerLab verified) are worth the small potential cost increase because the supplement industry is generally poorly regulated. Finally, I recommend avoiding proprietary blends that dont show exact B12 amounts, products combining B12 with stimulants or energy boosters (which is usually just caffeine driving the energy claim, not the B12), and anything making marketing claims about weight loss or metabolism, says King
