If your prone to anxiety Eq is not good for most. Sure smaller frequent injections are better but it's playing with fire. Boldenone propionate could be used too.
Tren was mentioned... best thing ever but again the anxiety will get really bad. I feel tren changes you mentally more than any other aas. If you have anxiety/depression issues it may cause havoc on your system. I believe tren e was a predominant reason I started getting panic attacks (they lasted over a week and my anxiety continued after that). Obviously if you ever did try it tren a would have to be your choice... small daily injections would be best.
If you really want to try mast go for it. It is the best compliment to test. I know many who use it in every cycle they do. It acts as an anti-estrogen. I don't believe in using AI's and SERMS unless I had gyno issues or started doing much higher doses. High estrogen is fine if your test is high too... the interrelationship between the two is important. Therefore mast is great with test. There is no need to go above 350mg for most but everyone is different. I feel really good on mast and have nice aggression... not rage like tren can bring but just a nice feeling. Just adding AI's are very important if you wish to keep dry and hard etc... letro dries you out in days and you can look a different person. But for on cycle protection I would recommend aromasin then arimidex a close 2nd.
For the reasons mentioned above I don't rec fina... again it is harsh on the system. I have heard of it but am not aware of the other drug you mention so can't really comment. Just keep your mast dose at a reasonable level and you should be fine.
Deca is great... I love it. Obviously diet dictates your goals but for things you listed test and mast would be excellent. Throwing in avar or tbol would be great too. Look it proviron too (not needed with mast). Then of course primo but it is pricey... I have yet to try primo but it is my no.1 to try so will do soon.
So yeah look into test and mast. Test and primo. Orals such as tbol and avar. I hope I have helped.
Wonderful post Elvia, very well done.

I'll spin off some of the things you said.
Let me start by saying I don't put a lot of stock in the myth that is roid rage. If you get irritable on AAS, likely you get irritable off them. Having said that, as someone who does have a short fuse off AAS, when I pair both mast and tren that fuse gets even shorter and I must have a constant cognitive control over my temperment.
I'll concur that it seems for most guys the sweet spot of mast is 300-400mg a week. If you have mast-p I'd say 100mg EOD is a simple and easy way to do it. I've used 600-700mg of mast a week and there was not a perceptible difference to me. So if 350-ish is all you need go with that.
Reminds me of an old principle regarding many things in life including AAS dosing: As little as possible, as much as necessary.
The reason so many call test mast tren the trifecta is it flat out works.
Again just speaking personally I dose test at 175-250/wk, mast around 350/wk and tren 525-700/wk. This just flat out works for me. Now I've tried this trio with varying doses and nowadays I actually use as little as possible [the above dosing] but it is enough to give me results. Since neither tren nor mast give cause for aromatization concerns you only need to work about estrogen from test and at 200-ish the mast only might be enough to handle that like Elvia said. Now granted if someone was running over a gram of test and pair that G+ of test with 350mg of mast I would not say definitively that the mast alone is enough to control estrogen; but thats a topic for another debate.
So again to the point at hand for the OP. Mast clearly seems like your next move. Whether you add the third compound of tren is your call. One thing to remember is with deca and tren the conventional so called wisdom is that one needs more test than the deca or tren. Myth. If you have a trt dose of test thats honestly just what you need for sexual function. So called deca dick is not a result of a lack of test but rather a side effect of the mere presence of deca itself. Thus its cure will not be more test but rather an ancillary which corrects a problem deca induced whether that be progrestin or prolactin related.
As always and like anything just keep your eyes open for sides/issues and have the proper ancillary in hand prior to commencing this run with whatever compounds you end up selecting.
