Masteron Vs Primobolan

[6ozSirloin]

Been seeing conflicting results, took a dive into the steroid * cycle thread and noticed alot more people than I thought are picking masteron as a secondary compound to testosterone regardless of cutting / bulking phases.

Curious about the general consensus between these two drugs. I feel like depending on the forum/Influencer (vigorous steve is a great example who definetely favours primo over mast) one is more perferred over the other.

I use primo with every phase and cycle.

Ive used both, I feel like I perfer primo more as it directly affects my estrogen and I use it as an ancillary or an AI (confirmed with bloodwork). It is also just much safer mg per mg than masteron on my blood levels (Despite being much harsher on my wallet mg per mg).

Doses ive ran: 100-400mg primo always with test at a higher ratio usually 1:2 (primo:test) or 1.5:2

No, primo tablets do not count and I refuse to recognize them as a potential oral for any scenario, unless maybe youre a female.

I want a general consensus, not what youd pick during a lean bulk or cutting phase, if you had unlimited budget what would be your go to to run for the rest of your future cycles.

Forgive me for sidestepping your question, I'm no authority on the subject either way. Just wanted to share a video from a different youtuber who takes an opposing stance to Vigorous Steve's position re: Primo VS Mast (etc).

Test, deca, proviron for the rest of my life non stop. Not expensive so budget isnt an issue. I mean unless your very high dosing and the food gets pretty expensive.

what does the proviron help with in a test/deca stack, I use mast to combat 19-nor sides will proviron do same?

Test, nandrolone and EQ. Dbol or anadrol for orals. Not all together of course. Nothing beats the bread and butter compounds.

 

[Sorbate]

depends on what you want to achieve.

Myself it’s more about being healthy as I age so pretty much test and primo.

If I was young and wanted to build the most mass and wasn’t worried about organs, test, dbol and pharma gh, with insulin.

To be honest, I find steroids to be pretty lack lustre. They are a great supplement, but never trumps the other two, eating and training. And I can spend what I want on gear, and lately my choice has been 200 mg of test.

 

[Sorbate]

I didn’t answer the primo vs mast thing.

I use primo because I feel like crap when I take mast. I believe that mast drops my estrogen more, or increases my dht too high, or reduces my SHBG too low.

Bumping this

Forgive me for sidestepping your question, I'm no authority on the subject either way. Just wanted to share a video from a different youtuber who takes an opposing stance to Vigorous Steve's position re: Primo VS Mast (etc).

I gave this a watch, really interesting stuff where Primo is compared at a molecular level to masteron, and it did confirm what I already knew about masteron being unable to function as an aromatase inhibitor, I didnt see him reccomend one over the other though, did you come to a similar conclusion?

 

[Pippyhippy]

As far as sides go primo stands alone. Mast was underrated and a solid compound but primo is thee best long term, markers, health.

 

[BanditNOLIMIT]

I've used my fair share of both of these compounds and prefer Masteron. Neither have a significant impact on my estrogen levels which sucks as someone who struggles to with managing that. For me, Masteron just wins across the board. Better gym performance, cosmetics, feeling "on", and of course a softer blow on the wallet.

Both are notorious for destroying HDL, however I've never noticed significant impact from either compound.

 

[bboy123]

if you had unlimited budget

Primo.

Whats your normal proviron dose.
I kinda like proviron even tho it doesnt do much and it feels like a waste until i come off it. Then i miss it

 

[storman]

As for primo or mast. I dont really like either. Primo is very mild and takes alot. Mast fucks with my prostate

 

[Mad Zuiki]

The 2 times I ran Masteron hair fell out of my head by the handfull , Not only that but all I could think about was Sex Sex and more Sex 2 the point I was Hitting on the Waddeling Obese that I would never even glance twice at in realities mind , Like women that out weighed me by double and I am 200 pounds " and I have a Hot Fit Girlfriend " so for me Primo all the way , I watched a funny video Titled Tren maid me Gay ! So some guy went Homo on Tren ! Well Masteron makes me want to smash and stuff Big Fat Cheese Burger McMuffin Lovin Princesses
So a Big F 2 the No for Masteron
And a Big Hell Yes for Primo !

I use 25 or 50 per day. I only would go higher then that for the hardening effect if i was really lean. I just use it for making me feel great overall. Im one of the guys that do notice it and like it. Always have since first trying it

 

[Mad Zuiki]

An older guy Buddy of mine Loves Masteron and Proviron he calls Proviron oral Masteron
He is in his 60s and makes most 30 year olds that go to the gym look bad , He swears by them both as a great finnisher when ending a cycle

 

[ajfromab]

masteron is the shit. makes you look wild, but i would personally save it for cutting phases. running it in my bulk was kind if a waste of money imo. i run primo all the time and its 5 star over the long period. i can run primo forever no issues. the masteron can sort of mess with my cholesterol so i have to keep it in check.

Would Masteron be an addition to your Primo, or a substitute when you use it?
