BPC-157 is a synthetic peptide, and when you inject synthetic peptides into your body, your immune system may decide theyre foreign invaders
Results After adjusting for Age, BMI, AMH, number of oocytes retrieved, cleavage-stage embryos/blastocysts, and the number of transferred embryos, when the vitamin B12 value was 358.7 pg/ml, for every 10 pg/ml increase in the vitamin B12 value, the clinical pregnancy rate increased by 4% (OR=1.04, 95% CI=1.00, 1.08, P=0.03)
A third is failing to let the solution rest briefly after swirling, which can leave undissolved particulate that affects the consistency of later measurements
A stability study published in the Journal of Pharmaceutical Sciences (2021) found that BPC-157 in aqueous solution retained greater than 95% of its original purity at 4 C over 30 days but degraded to 81% purity at room temperature (approximately 22 C) within the same period [10]
