Hi fellas, thanks for letting me join.
I'm 6'4", 225lbs, former athlete (pro mma) I'm 51 and still an avid gym rat. No stranger to aas.
Question: I'm currently on TRT. 200mg/wk Test Cyp. With an estrogen blocker. I want to stack with Masteron. An experienced friend told me that with Masteron an estrogen blocker was absolutely not needed. Even though im on Test as well?
I understand that Masteton does not aromatize. But Test still would. Wouldn't it?
Any input would be greatly appreciated.
Thanks

From my understanding it will mask some of the symptoms of higher E2 levels but doesn’t actually lower the number on paper. I will let someone a lot smarter than me confirm this though

it’ll prevent some estrogen from binding but most will still bind. Chances are youll still need an ai
 
Thats such a low dose an ai probably wouldn’t be needed but only bloodwork can tell. Do you have recent labs?

If you’re using an AI already on 200mg Test chances are that you will need one with Mast also, but hopefully less AI. Try 200/200 Test/Mast and see how it works for you, it’s unfortunately not the same for everyone.
 
I do.
1st lab, baseline. No trt. : test = 386, estradiol = ?
Lab1of trt: w/ 200mg test/ week no blocker
Test = 1573 estradiol = 103
Lab 2: 100mg test/wk 1 arimex/wk
Test = 400, estradiol = 44
I'm going to go back to 200mg/wk of Test as I'd rather be higher than lower.

My body is extremely sensitive/responsive to AAS. Always has been. I can't do nearly the dosage that other people do.

What AI are you using and what dosing protocol are you following?

Those numbers you posted above is fairly normal, I get as high as 1800’s on 200mg for an example and my Estro can get around the same as you. Start with 200/200 Test/Mast and see how you feel.

Btw if you don’t already have the Mast, be careful when you order, it’s a shortage right now of Mast.
 
In “most” people Masteron will have little effect on E2.

If you want estrogen suppression from gear look I to Primo and/or EQ.

Normal is ~20:1 so for instance 1200 ng/dL total test, 60 pg/dL. The ratio is more important than the number to a point. So, you are slightly high on your 200 mg/w. Really, decent is probably 15:1 to 25:1. It depends on your tolerance to estrogen. Masteron will act like a SERM like tamoxifen so it will block some estrogen, which is fine for estrogen control. You will look leaner and drier especially if you are on the lean side. I would not do both AI and Masteron. For me, I would get achy joints. I would be able to do well on 250 test and 300 Masteron.

When you say “to a point”, could you elaborate on this?
For example, I’m on trt and had TT of 787 and e2 of 52 starting out, and also had spicy nips.
Am I understanding you correctly that even if my TT was 1000, and my E2 was 52 (the ratio is lower), that I would or would probably not still be facing the same symptoms? I know there’s not a definitive answer, just wanting to make sure I wrap my head around this correctly.

Seems there are a few different E2 tribes and it can be frustrating for a noob (or anyone for that matter) to figure out what’s best. Comes back to “everyone’s different” most of the time.

Tribes:
-Keep it in range. Period.
-Keep it close to in range with no symptoms (but no hard number target)
-Just manage symptoms no matter the number
-Just manage symptoms as long as it’s not “too high” (no target number but don’t let it get “too high”)
-Keep T:E ratio of 15-25 with no symptoms (sub tribe of that “but not ‘too high’”)

In the end, it seems E2 is a choose your own adventure book, as the advice I’ve scoured here and elsewhere spans pretty much all the above.

To me, no symptoms makes sense, no matter the number. Also staying somewhat close to range (but here some tolerate higher E2 well so it gets fuzzy - I don’t feel it until I’m in the 90’s, but I don’t run it that high anyway). There’s some risk to higher E2, but it’s not clear to me from the literature where that starts (50’s, 60’s, over 100, a point over normal?).

PEDs use entails some health risk. High E2 probably does as well. So it’s a matter of balancing risks and comfort. I lean toward risk minimizing (not eliminating or I wouldn’t be on this forum, obvs), but it’s an individual thing in the end

This is the answer to almost everything. Having set ranges, ratios, etc is counterproductive.

Soe people feel great and have zero sides with E2 at 90, while someone at 60 is getting gyno.

Get bloodwork, see the data, monitor how you are reacting mentally and if any sides are being seen. Of course, if you're blood work shows it's crushed or through the rood that's a different story, but for the avg lifter don't make it harder than it needs to be.

The body is not a textbook the sooner people realize that the better they can dial everything in. "So and so told me or I hear" people need to stop and figure themselves out.

With my T =1573 & E = 103 my temper had no fuse! Slightest thing and I was "Hulk smash" status. After the AI my Estro went down to 44 and my temper was back to normal. I know its trial & error and "what feels right". But wanted to other people's opinions & experiences. Also, (a hard habit to break) is that I'm a numbers person. So....
 
So this was my experience with Mast. I tried it out once, along with my 100 mg test c , ran the mast 1:1 . I kept reading about how well it paired with TRT so I got the bug, only thing I can say for sure was a bump in libido, saw nothing in E2 change, but it’s pretty small dose so…as far as Ai goes , again for me, my endo started me out really high at 5 mg. of Anastrozole, which when looked into it, it looked like over kill, my E2 at the time was 200 and I guess she wanted to get it down fast, anyhow I started lowering the amount on my own and did my labs, I got it down to 2 mg. And I knew something was changing , got my labs and my E2 went from 40 to over 70, this is all based on 100 mg of test c per week. I could feel” my libido going down , plus just didn’t feel as good, so for me I went back to 3 mg a week and I feel like I did, it still seems like a lot, but the bloodwork doesn’t lie. Sorry for the long post.

Dude I totally get it! I’m a numbers guy, too, and want to target specific things wrt bloodwork and doses and all kinds of correlations.

What I’ve found (for myself) is that even the numbers can be misleading depending on what aas you’re taking. Like I “feel” E2 levels less when I run masteron, but the levels are high nonetheless, so I need to manage them somewhat even so. Without mast (say with EQ or NPP), I “feel” the emotional E2 sides at lower levels than when I have mast on board. So my management of E2 doesn’t change much, but I tend to implement an AI earlier and at a slightly higher dose to prevent the “hulk smash” or “hulk sad” modes

The more I’m at this (and I’m a noob for this by the standards of this board, for sure), the more I get why people say to start with test and learn your reactions at different doses and how to handle them, add one compound and learn the same, add a different one and learn, then think about combining (like test, EQ, NPP after running each pairwise) and learning that.

And everyone is different, which is the most frustrating thing lol. That said, I still think that learning different people’s experiences teaches you what to look for and how they handled it.

While the plural of anecdote is NOT data, it helps. ;)
