Adding the clinical framing, because it changes how the question reads.
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.

Compounding pharmacy customer here with experience relevant to compounded supply.
I've ordered from 2 different compounding pharmacies over the past 2 years. The quality variation is real — purity ranged from 94% to 101% of label claim based on independent Janoshik testing.
My current compounder (a 503B facility) has been consistently 98-101% purity across 10 orders. I pay $165/month vs $1,355 for brand. The savings are substantial and the product is equivalent in my experience.
Re: compounded supply — this applies whether you're using brand or compounded. The clinical principles are the same.
