I'd say 10-Undecenoic acid.@janoshik Would you concur that, based on the GCMS results, the main impurity in the Boldenone Undecylenate raws is most likely free esters (peaks #1 and #2)?
Based on my limited knowledge and experience I'd guesstimate that 10-Undecenoic acid is the main and mostly only impurity and it is not quite volatile (so you are not seeing it in the GCMS). However, some of it did form methyl and ethyl esters (#1 + #2) which are volatile and can thus be seen.
noAnd that the remaining impurities are free Boldenone, which potentially doesn't show up due to co-eluting?
