so if you’re mid-protocol on bpi compounded tirz and you switch to something else, you’re changing suppliers, batch source, maybe concentrations, and honestly everything at once. i get the fda is doing fda things, but teh confound keeps gnawing at me. if tirz “worked” on bpi for three months and then you switch and your results shift, you have no idea which variable caused it. was it tirz wearing off, the new batch weaker, placebo settling, your sleep that actually changed. i’m tracking my wrist (bpc) and logging injection site lumpiness and sleep so when something changes i have something to compare to. if you’re switching suppliers and just continuing, you’re not getting data, you’re just getting vibes. idk if anyone’s writing down which batch you were on and when you switched, but track the supplier change for 6-8 weeks and you’ll actually know what caused the shift. without it, you’ve got nothing to compare. that’s my take.
