Also known as Ibutamoren
A non-peptide ghrelin mimetic, usually supplied as a powder or solution rather than a lyophilised vial. Substitution with cheaper research chemicals is a documented problem.
What we measure
- HPLC purity (%)
- Identity by LC-MS/MS
- Measured content (mg)
What tends to go wrong
Substitution with unrelated compounds is well documented.
This is a pattern we see across submitted samples, not a claim about any particular vendor. The only way to know about your vial is to test your vial.
