Primo will not aromatize at all, and also supposedly has mild anti-estrogenic properties. So at least for the primo part of your cycle, you will not need an AI.
I wouldn’t feel comfortable recommending a dose, but my experience is as follows. First time I did Primo was 800 MG for I believe 14 weeks. I think it was real, not sure if it was properly dosed, and honestly I’m not sure how effective it was because training and nutrition weren’t ideal I was playing around with some other compounds and I didn’t do it right. I recently Did an unorthodox primo
cycle, with what I’m very confident was legit product. 6 weeks total, Front loaded 2000 MG the first week, and then 1000 MG per week for the next five weeks. Started working quickly, and I gained A good amount of hard, quality muscle. Became more vascular. Very modest strength gains, but Primos not known for big strength gains. But I was extremely happy with the results for a six week cycle. High BP when my frontload hit me, but went away and Only side I really had was inability to bust a nut starting around two weeks in i think and for the remainder of the cycle. Not a great side effect have, but unfortunately I am prone to sexual sides from aas. Another reason I like short cycles. Cycle ended two months ago, and still holding most of the gains on a TRT dose. Most people would say you need to run primo at least 14 weeks minimum, I’m not sure how effective my cycle would’ve been if I had run it much longer, but I like shorter cycles in general for number of reasons, And have noticed greatly diminishing returns after weeks 6 to 8. But if you can get real Primo, and can afford it, I highly recommend it. A typical primo cycle would be like 600-800 mg or even 1000 for 14-20 weeks. If you’re looking at orals, I would recommend tbol. I’m somewhat older guy, and am prone to BP issues, so I cant touch anadrol sdrol or dbol, So my options for orals are limited. Done var it was okay, but love tbol. very nice strength gains, decent size gains, quality muscle like primo, and no sides whatsoever for me except of course some stress to the liver. Although I have heard people mentioning they had blood pressure issues on it, this was not the case with me even though I am prone to that issue.
