Two products can look identical and produce completely different experiences. The difference almost always comes down to one thing: verification. Purity. Handling. Most people skip this step. It's the most important one.
I don't recommend sources casually. Every lab listed on this page runs regular third-party testing for identity confirmation, purity, endotoxins, and heavy metals. That level of verification isn't a bonus — it's the baseline for responsible use.
Sourcing isn't a detail. It shapes everything that follows.

These are the only sources I personally use and recommend. If a lab isn't on this list, I haven't verified it. That's not a judgement — it's a boundary. Your biology deserves the same standard I hold my own protocols to.
Sourcing is one piece. Knowing which peptides to source, at what dose, and in what order is another. That's what the Consultation is for.
