Each test can be added to a package or ordered on its own. Results arrive in 3 to 5 business days.
Included in every package
How pure the TP-508 is and how much is in the vial: purity in area percent, quantity in mg per vial against the label. Details
Included in every package
Whether the sample contains TP-508, compared with a reference standard. Reported as match or no match. Details
Quoted
Whether the molecular mass matches TP-508, which helps catch look-alike products. Details
$70
How much TFA, acetate or chloride the powder contains. Other salt forms are quoted. Details

Sequence not shown: no sequence could be confirmed from a public record. Formula, mass and CAS number are from the PubChem record under Sources; send the expected sequence and mass with your sample and identity is checked against them.
TP-508 runs on the lab’s peptide purity and quantity method: reversed-phase HPLC on a C18 column with a water and acetonitrile gradient containing 0.1% TFA, and UV detection at 214 to 220 nm. Purity is the main peak’s share of the total peak area, quantity is measured against a reference standard, and identity is confirmed by retention time and UV spectrum against the same standard. LC-MS confirmation of the mass is quoted separately.
Send 1 vial for Level 1 Silver, 3 vials for Level 2 Gold or 4 vials for Level 3 Elite; raw powder purity needs a 50 mg sample. Results arrive in 3 to 5 business days; sterility takes 14 days.
Yes. LC-MS identity, quoted separately, checks the measured mass against the 2310.03 Da monoisotopic mass in the PubChem record.
Quantity is reported as peptide in mg per vial. Acetate or TFA counterions add weight to the powder but not to the peptide result; the counterion test ($70) measures them.
