GSH depletion causes ferroptosis in RPE cells To evaluate the mechanism of cell death in GSH-depleted cells, we treated RPE cells with various cell death pathway inhibitors including ferroptosis inhibitors ferrostatin-1 (Fer-1, 8 M), liproxstatin-1 (Lip-1, 600 nM), iron chelator deferoxamine (DFO, 80 M), pan-caspase inhibitor z-VAD-fmk (30 M) to inhibit apoptosis, autophagy inhibitor 3-methyladenine (3-MA, 10 mM), and lysosomal inhibitor bafilomycin A1 (Baf-A1, 75 nM)
The regulatory landscape is evolving: in February 2026, HHS announced that approximately 14 previously restricted peptides including BPC-157, TB-500, CJC-1295, Ipamorelin, and Sermorelin are expected to return to Category 1 compounding status
For those using DSIP to manage stress or anxiety, it may be administered during the day as needed
Scientific studies have explored Ipamorelin to better understand its role in endocrine signalling, metabolic regulation, and growth hormone physiology within experimental models
