Studies have shown that oral collagen can be absorbed at rates as high as 63%, compared to 1-2% for other oral peptides.12 13 Injectable collagen peptides are available, too, but surveys show a large proportion of the population would prefer a less invasive method.14 BPC-157 is another peptide that boasts good oral bioavailability, but the same cant be said about its frequent companion, TB4.15 16 Because we recommend BPC-157 and TB4 in combination, and because BPC-157 can be hard to find in oral form, BPC alone failed to earn our designation as the easiest-to-use peptide

Other studies emphasize the crucial role of the p21 protein in maintaining the senescence phenotype [50]
