The isotope pattern is consistent with the elemental composition of L-Glutathione (reduced). That is a second, independent check on identity and it agrees with the mass.

Section 2
Annotations
Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it. Where a handle has made the same point on several records, one instance is shown and the rest are reachable from the records themselves.
Identity confirmed and purity at 98.23 %. The two answer different questions — what it is, and how much else is in it — and a record carrying both is the version worth citing.
The isotope pattern is consistent with the elemental composition of GHRP-2. That is a second, independent check on identity and it agrees with the mass.
At this mass the monoisotopic peak may not be the most intense peak in the cluster. Picking the apex instead of the monoisotopic peak produces a systematic positive error of roughly the size flagged here.
The isotope pattern is consistent with the elemental composition of BPC-157. That is a second, independent check on identity and it agrees with the mass.
An orthogonal identity method on the same lot would make this the strongest class of record the index holds. Mass plus retention is already better than most.
The isotope pattern is consistent with the elemental composition of LL-37. That is a second, independent check on identity and it agrees with the mass.
Nothing here rules out a positional isomer with the same formula. Mass cannot; only chromatography can, and the gradient length on this record is the relevant fact for that.
The isotope pattern is consistent with the elemental composition of Liraglutide. That is a second, independent check on identity and it agrees with the mass.
The isotope pattern is consistent with the elemental composition of CJC-1295 (no DAC). That is a second, independent check on identity and it agrees with the mass.
Mass, retention and impurity profile all agree on this record. Three independent constraints pointing the same way is the strongest identity evidence the index publishes.
Identity confirmed, purity 98.03 %, mass balance closed. This record is complete against the index definition of complete and there is nothing outstanding on it.
