I'm using a 23g x 1 inch (0.6 x 25 mm)
The standard KLOW dose for women remains 3.2 mg per injection: 2 mg GHK-Cu plus 0.4 mg each of BPC-157, TB-4, and KPV
What the evidence does support is this: B12 deficiency causes fatigue and neurological symptoms, and correcting deficiency in people who are deficient improves those symptoms
see Table 1) ( While European guidelines recommend up to 4 g/day for adults, most of the included studies administered pharmacological doses ranging from hundreds to thousands of micrograms
Evidence GHK-Cu is associated with regulation across more than 4,000 genes, including collagen synthesis, antioxidant defense, wound healing, inflammation, and tissue breakdown
[14] The NHS notes that taking up to 2 mg per day is unlikely to cause harm
