FOXO4-DRI is a roughly 5.4 kDa, strongly cationic TAT-fusion peptide, and cationic peptides tend to bind extracellular matrix at the injection site, so subQ delivery could plausibly be substantially lower than IV
However, that was long before the substantial expansion of our state of knowledge regarding dry eye, Meibomian gland dysfunction, blepharitis, and ocular rosacea which has taken place over the last few decades
Some practitioners theorize that IV administration might provide advantages for certain applications, though clinical evidence supporting superiority of IV over IM administration for most wellness purposes remains limited
Individual tolerance determines the specific schedule for each recovery period
If you dont see a lot of bubbles after the first feeding, try a little whole-grain rye flour with the next feeding
It can provide valuable insights into the peptides mechanisms and applications
