As organisms age, the natural decline in plasma GHK-Cu levels correlates with diminished skin thickness, reduced collagen density, and impaired wound healing responses
Volume of Research Total published studies : Approximately 30-40 peer-reviewed papers specifically on BPC 157 Period of research : First studies emerged in the mid-1990s, with most research occurring in the last 15 years Primary research centres : Most research has come from universities in Croatia, with additional studies from China, the US, and various European institutions Animal models used : Primarily rats and mice, with limited studies in larger animals In vitro studies : Several laboratory studies examining cellular effects Quality and Limitations of Research Human clinical trials : Extremely limited, with only a handful of small pilot studies Sample sizes : Most animal studies have used relatively small sample sizes (10-30 subjects per group) Study duration : Typically short-term, ranging from days to a few months Replication : Limited independent replication of key findings Funding sources : Many studies have been conducted by the same research groups Publication bias : The Possibility of unpublished negative results Research Gaps Important areas with insufficient research include: Long-term safety : Minimal data beyond a few months of use Human efficacy : Lack of large-scale, controlled human trials Interactions : Limited understanding of interactions with medications or other supplements Dosing optimisation : Lack of clear dose-response studies Delivery methods : Limited comparison of different administration routes Genetic factors : No research on how genetic variations might affect response Sex differences : Limited research on potential differences in male vs
