Primo or Mast

Depends. Moody as in weepy sitting around watching The Notebook? Or moody as in your act like an asshole switch gets flipped real easy? The latter is a likely sign of low E2. Easily angered, angry for no reason.
Moody as in get teary reading bed time stories about unicorns to my little girl.

I'm never reactive, people could get hurt.
 
I love Primo. But getting the test to primo ratio correct is a work in progress. I crashed my E2 so now I’m hitting pause and will try again in a few weeks. My libido was also great until I increased beyond 300mg and hit 400 a week. In fact Primo put my libido in overdrive.
In these situations take dbol and hcg/test prop until you get it configured. Just take note of what ratios are too harsh and adjust pin by pin.

A nice little trick I like to do is lets say one pin of 60/60 test/primo e2 gets low, and you’re now leaning towards 60/40 test/primo, you could just take 60/20 the following pin to correct the previous pin and move forward from there.
 
They're virtually interchangable and masteron is usually cheaper so that's my pick

Masteron blocks estrogen in the breast so less chance of gyno. Primo instead lowers e2 in most people so it's harder to dial in.

Why are they considered interchangeable when they do completely different things? Isn’t primo more comparable to eq?

I meant more in terms of anabolism and neural drive. Sorry, should have clarified that

EQ lowers e2 in some people, not all. Some people will get higher e2 since it does aromatize

The biggest difference between Primo and Mast is the amount you need to mitigate e2 sides.

Primo has a much stronger anti estrogenic effect, which is why it shines better for growth phases w higher doses of test where more e2 management is required.

If you tried to run a high test cycle w/ Mast, you are going to need a lot more of it for the same result as w Primo, which is going to have a harsher effect on lipids and limit how far you can push the cycle.

Masteron is much better for cutting where you’re running a much lower test dose; much less e2 management is required, so it makes sense to pick the cheaper compound to mitigate, in addition to being able to run more total milligrams a week.
 
Test 300
Mast 200
Tren 100

That’s looking like a decent cycle.


I’ve been researching different compounds and how much the tissue they can add in 12 weeks (providing diet training, stress levels-and sleep are on point)

Test 300, Tren 100, Mast 200: 3-7.5 kg (7-16 lbs) of muscle gain

• Test 500, Primo 400: 4-6.5 kg (9-14 lbs) of muscle gain

I dont think this is the mindset to have when picking compounds. You have a goal for your cycle, and you want to use the right tools for the job.

Test is for fullness and estrogen production; Masteron is for conditioning (anti estrogen);Ttren is for maintaining strength in a severe calorie defecit (anti catabolic);
Primo can be used as an AI for sides that cant be mitigates by a SERM / Mast (mental sides, blood pressure, etc)

Theres no point running tren until youre at the peak of your cut and eating a stupid low amount of cals, otherwise id just keep losing weight on just test and mast if cutting is your goal. You also could use anavar instead for this purpose if you just need to focus on fat loss, tren if youre trying to do a serious recomp, but I dont think the sides are worth it.
 

Dr Todd Lee is a crack up. He is always contradicting himself in his videos. This does not mean he does not provide valuable information.

The moral of the story is everyone responds differently to each compound and you need to find out how you react.

Example, I am currently trying Primo for the first time. So to prepare myself I raised my E2 to 126 to hopefully prevent an estrogen crash. My current dosing is
200 Test-C
400 Primo
300iu HCG EOD
3.6iu GH PM
20mg tamoxifen ED (don't want gyno with this high AF E2)

On Feb 4th I will get blood work (4 weeks in) to see how I react to primo. If E2 is still high I will increase primo. If E2 is low I will increase Test.

Fair, I haven’t seen a lot of his videos, just got turned onto him recently. I tried primo a few times and even after one dose I just feel terrible and get a huge injection welt and knot that lingers for 5 days. May try another brand but mast has like no observable side effects for me except shedding which Todd Lee says is impossible but definitely started when I started taking mast lmao

I think his perspective is very entertaining but I def would not listen to his opinions on primo vs mast; I think he’s overly biased towards mast just because he PERSONALLY had a bad experience w Primo (my assumption)

The fact he think you can run an infinite dose of mast w no consequence blows my mind, there absolutely a limit to how much you can take base on your test based, you will eventually get low e2 sides.

As I said before, mast for lower test doses, primo for higher ones, thats the way to go imo.

Try Primo 100 or 150 if you can find it. I was having issues with Primo 200 once I increased over 200mg a week. Knots and inflammation in my quads which is where I prefer IM. But I switched to Primo 100 and that stopped. I want to grab some of Stan’s 150 GSO when he returns and test it out, plus a vial of his 200 MCT. It’s possible the issue for me was the source and not all Primo.

lol if primo affects your e2, good luck with that, i added 150 primo to 275 test and my e2 from 106 went to 34 in just 4 weeks. I guess with primo double my test dose it would have went -34 haha

I appreciate your sentiment, and I’m not arguing, but tren is 5 times stronger than test, and I think a moderate dose of test and tren could be really good for a lean bulk.

It’s gonna be a much dryer cycle and will add quality tissue. With test, I blow up and lose a lot of my gains post cycle. Yes, I still smash the gym, diet, sleep and a good PCP. It makes no difference.

Test, Tren Mast he’s gonna put on slower steadier leaner gains that don’t just fall off when you stop. Plenty of people bulk on tren.

At the end of the day, if diet sleep and training are on point, you’re gonna put a good amount on the test alone. 100mg tren isn’t going to hold you back or make a huge diff vs 100/200mg more test.

The results won’t be that different I don’t think

Holy crap! So far I have no symptoms of low E2. In fact, my skin is kind of oily so I was thinking my E2 is still high. I will definitely let you know what happens. lol
