Here is a list: 4 androstenediol (4AD or 4diol) converts to testosterone 19 nor-4-androstenediol (Nordiol or nordiol) converts to nortestosterone or nandrolone 1 androstenediol (1AD) converts to 1-testosterone (dihydroboldenone) 1,4 androstenedione and 1,4 androstenediol (1,4andro or Boldione) converts to boldenone and slightly converts to estrogen (the diol version does not convert to estrogen) 5 alpha androstenediol (5AA) converts to DHT 3 beta androstenediol (3 beta) converts to DHT 3 alpha androstenediol (3 alpha) converts to DHT 4 hydroxy androstenedione converts to 4 hydroxy testosterone which is an aromatize inhibitor (blocks formation of estrogen) 7-KETO-DHEA does not convert to any active anabolic compounds 1-testosterone (1-test) is already an active compound and does not need to undergo conversion Compounds you want to avoid: 5 androstenediol (5AD or 5diol) converts to testosterone at a very low rate and is an estrogen agonist 4 androstenedione (andro) converts to testosterone and estrone (estrogen) 19 nor-4-androstenedione (norandro) converts to nortestosterone and estrogen DHEA converts to androstenedione and can be converted to all other hormones Pregnenolone converts to progesterone and can be converted to all other hormones 5

In the absence of MTAP, the substrate methyl thionyl adenosine (MTA) accumulates and acts as a selective inhibitor of PRMT5 to inhibit PRMT5 methylation activity, 237 whereas MAT2A can produce the PRMT5 substrate SAM, 238 allowing PRMT5 to exert its oncogenic effect
