How to read a Certificate of Analysis, and what it cannot tell you
What a Certificate of Analysis records, which four fields matter, why the lot number is the load-bearing one, and what a COA cannot tell you.
What retatrutide costs, and what the price is actually paying for
Retatrutide 10 mg from $84, 20 mg from $120, 30 mg from $185. What drives price differences between suppliers, and why per-lot testing is part of the cost.
Is retatrutide FDA approved? The regulatory status, stated plainly
Retatrutide is an investigational compound and is not FDA approved for any use. What investigational status means, and what research use only means.
Does retatrutide need to be refrigerated? Storage and handling of lyophilised material
Sealed lyophilised retatrutide is stored at −20 °C or below, not in a refrigerator. Why the dry sealed state matters, why vials are equilibrated before opening, and why ambient shipping is normal.
