Shipping times with Cardinal Metabolic Clinic, post yours

Adding a datapoint rather than asking anything.

Honestly I only picked Cardinal Metabolic Clinic because they were cheapest and had a working checkout, which in hindsight is not a great way to choose.

Trying to work out if what happened to me with Cardinal Metabolic Clinic was a one-off or a pattern.

Worth noting there’s an Index Score of 87 for them published, which is more than I expected honestly.

Happy to be told I’m wrong, genuinely.

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

Correct, and the same applies to the quantity assay.

Mass spec gives you molecular weight, which confirms identity but says nothing about whether the sequence is correct. Two different peptides can share a mass.

That is the distinction I was trying to make, said better.
