Institute GHRP-2 results thread, discussion

Searched first, found bits of this scattered across old threads, so figured I’d start a proper one.

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

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.

For what it’s worth the Institute has 4 published GHRP-2 reports, which is where I started.

Not looking for anything other than what people have actually run into.

Worth separating two things here. Purity tells you what fraction of the material is the target compound. Identity tells you whether the target compound is what the label says. A product can pass one and fail the other, and they are different assays.

For anyone arriving from search: the compound reference page has the evidence grading, and the testing tab has the actual results. Two different things, easy to conflate.

Correct, and the same applies to the quantity assay.

Yes, and the same page has the older cycle for comparison.

Quantitative amino acid analysis is what actually verifies content. Weighing the lyophilised powder does not, because you are also weighing residual salts and moisture.

Good thread.

To answer the methodology question directly, Purity & Testing carries 25% because it is the dimension we can measure most reliably. The full weighting is published on the methodology page.
