Studies have demonstrated that GPX4 is markedly upregulated in the luminal androgen receptor subtype of TNBC, thereby conferring resistance to ferroptosis [83]
BPC 157 was given per-orally, in drinking water (10 g/kg or 10 ng/kg, 0.16 g/ml, or 0.16 ng/ml 12 ml/rat/day) till sacrifice, or alternatively, 10 g/kg and 10 ng/kg intraperitoneally once daily
This allows not only greater effectiveness but also helps avoid unnecessary strain on the body
Budget and availability may play a role in the decision-making process, especially when considering the long-term use of either peptide
Plasma GHK-Cu concentrations decline with age, from approximately 200 ng/mL at age 20 to under 80 ng/mL by age 60, correlating with reduced skin repair capacity
