How do I verify a COA for GHRP-6 myself?

Fair warning, this is long. Summary at the end.

I keep seeing people wave COAs around like they settle the argument. They don’t, and I say that as someone who used to do exactly that.

Tried to verify a COA myself by emailing the lab on it. Never heard back. Not sure if that means anything.

Went through the Institute reports on this and it’s genuinely useful, but I only understand maybe 60% of what I’m looking at.

For what it’s worth the Institute has 1 published GHRP-6 report, which is where I started.

Things I still don’t know: whether any of this is batch-specific, whether it holds outside the one case I looked at, and whether I’m reading the numbers right in the first place.

TL;DR: not sure what to believe about GHRP-6, the sources people cite don’t say what they’re claimed to say, and I’d like to hear from anyone who’s actually looked at this properly.
