What's in the vial
Ipamorelin and Tesamorelin in one lyophilized vial. The blend is made and tested as its own lot, so its report covers the mix you receive, not the single peptides.

About the components
Ipamorelin
A synthetic pentapeptide described in 1998 as the first selective ghrelin-receptor agonist.
Tesamorelin
Full-length human GHRH with a hexenoyl group that protects its N-terminus.
Each component has its own page with sequence, formula and research background.

How each lot is tested
Samples from every lot go to an independent, ISO/IEC 17025 accredited lab. Its report covers three tests:
- Purity by reversed-phase HPLC: the main peak's share of the total peak area.
- Identity by mass spectrometry: the observed mass of each component should match its expected mass (Ipamorelin: 711.9 g/mol, Tesamorelin: 5135.8 g/mol).
- Endotoxin, measured for every lot.
The lot number on your vial is the number on its report. How to check a certificate of analysis walks through what to look for.
The amount on the label is the weight of the powder. Besides the peptide it includes counter-ions and some water; Purity vs. peptide content explains the difference.
Storage and handling
Store unopened vials at 2 to 8 °C, away from light, as printed on the label. Let a cold vial reach room temperature before you open it, so moisture doesn't condense on the powder. More bench habits are in Handling.
