No. The $250 test covers identity, purity and quantity by a chromatographic assay, with detection selected for the compound. Full testing to the USP Dihydroxyacetone monograph is available and quoted.
Solid DHA is normally a dimer that slowly turns back into the monomer once dissolved. The assay should account for this so results reflect total DHA.
DHA is sensitive to heat, light and high pH, and breaks down to products such as methylglyoxal and formaldehyde over time. Cool, dark storage helps keep results consistent.
DHA absorbs only at low UV wavelengths, so the lab uses a detection method suited to the compound.
