seems plausible that if primo inhibits estradiol conversion then DHB would to a certain extent too. But the thing is it varies from person to person.
Ratio of 2:1 might not work for some guys to really block estradiol on test: primo...some/most might need 1:1 to start to drop estrogen.
Remember, trestolone is itself a progestin and has affinity for the estrogen receptor too so it is theorized....so before its even converted its giving you progestin/estrogenic effects. You can block some of the metabolites with an AI or with primo but really man, use common sense, how much are they really effecting you at a total dosage of 100mg ment/week? That would be hardly anything if ment converts to methyl e2 at roughly the same rate that nandrolone converts....even if it converts at the same rate as testosterone....its still minuscule. The drug itself is activating estrogen and progesterone receptors and the only way to block that is to run a SERM while using it and control the total dosage.
100mg ment/week shouldn't be a big problem for most people especially you run some kind of dry anabolic like primo or DHB or anavar, whatever.
Your best bet is to run 60mg ralox and start with 5-10mg trest a day and titrate upward. I got to 15mg a day before I got into problems, even with 60mg ralox and an AI....you can run as much AI as you want, you'll crash your estrogen and you'll STILL have high estrogen sides because ment itself is an estrogen in action. Its a synthetic estrogen/progestin you're injecting.
