2.4 mg was the dose advanced into Phase 3 because the efficacy/tolerability ratio peaked there
Can I Use GHK-Cu Twice a Day Every Day Forever
However, BPC 157 is relatively stable and small dose ranged between ng-g/ml or ng-g/kg is already effective on promoting tissue injury healing and angiogenesis in many animal studies 4,27,28,29,30
In animal studies (pigs), strong systemic wound healing was induced at approximately 1.1 mg/kg body weight, roughly 300-fold below GHK-Cu's established toxic threshold in the same model
The absence of toxicity in a 90-day rat study is a positive signal, but it's not a guarantee of human safety at equivalent timescales
Recommended for those with low B12 levels or anyone seeking a natural energy lift.
