The 19-Nor-DHEA would convert to DHT, but only a little so I doubt it would provide enough of a Test Base for LGD. LGD has super lethargic side effects in some so you'd want a pretty strong Test Base, something like OL's Super-DHEA, Dermacrine, 4-Andro or EpiAndro.
Test Base+Spartan Mass+LGD would yield some pretty impressive gains tbh, especially if you had everything else dialed in right
