NETs are flavoring, WTAs are a form of nicotine that may have a slight flavor. The only substantial relation is extraction from tobacco.
n-e-t .com has done testing of their NETs and they actually test the extract rather than ejuice made from it for greater sensitivity. Trace levels of TSNAs and diacetyl even then.
I haven't tried that Analogs flavor but everything except Wrangler I've liked of Goodejuice NETs. Patriot especially, however that's also an example some extractors aren't sure is 100% NET because they can't explain the flavor.
