Then comes the experience of brighter skin and many health benefits with glutathione, often called the mother of all antioxidants, in your skin lightening IV drips.
GHK-Cu cycling - typically 30 days on / 14 off or 8 weeks on / 4 off - produces comparable results, reduces cost, limits theoretical copper load and keeps receptor sensitivity fresh
The loading phase builds tissue concentration over 4 to 6 weeks, after which maintenance dosing preserves benefits with reduced frequency
The body has finite capacity to use BPC-157 for healing, and exceeding that threshold provides no additional benefit while depleting supplies faster
