Reddit threads asking for the best peptide companies produce the same thing every time: a list of vendor names, a few enthusiastic replies, a few warnings, and no data. The useful posts are the ones that describe how the poster verified the material.
How to read a vendor list
- A name with a lot number and a certificate attached is a data point. A name alone is a preference.
- Look for posters who sent a vial to an independent lab and posted the result. Those are rare and worth more than the rest of the thread.
- Note the date. Suppliers change; a 2023 thread may describe a company under different ownership or a different manufacturer.
- Discount both the loudest praise and the loudest complaint, and read the ordinary replies in between.
