All true, with one condition: that curve is for people who reached the dose on schedule. Anyone who slowed the ladder for tolerability is on a different, flatter curve, and comparing yourself with the published mean will make you feel like a non-responder when you are not.

Bookmarking. The distinction being drawn above is the one nobody else makes.

This is where I part company with the consensus forming above. The trial means are being read too generously in this thread. STEP populations were selected, supported, and titrated by protocol, and the real-world curves are consistently a few points worse. That difference is not noise, it is what happens when you remove the study infrastructure.

Compounded semaglutide formulations for compounded supply: some pharmacies add ingredients like B12, L-carnitine, or BPC-157 to their semaglutide preparations. Are these beneficial or marketing gimmicks?
My take: B12 addition has some logic (GLP-1s can deplete B12). L-carnitine evidence is weak. BPC-157 for GI protection is theoretically interesting but unproven. I prefer straight semaglutide with no additives — fewer variables, cleaner data on what's working.
