Masteron or primo what is your experience?

I know genetics is the primary factor but is hair loss guaranteed with any of these 2?

I’ve run both extensively.

- Primo : more expensive, gave me noticeable gym and aesthetic gains but only at the tail end of a loong cycle - 20 weeks. Had noticeable BP and Prostate sides. Crashed my E2 with it because I liked the gains so much I went over 1:1.

- Mast : affordable, gave me next to no gym (strength) gains. Aesthetically there is some benefit but seems to make muscles just harder and a bit more grainy…primo was definitely fuller but less definition. BP side is still present, seems to be the perfect AI at 1:1, my sex drive and performance is great, no prostate problems.

If I was a pro body builder and spending the extra money was in benefit of my career, then primo is a no brainer. As a normal human who is on gear and has bills and a gf I like to have sex with, mast all the way.

What dosages were you running?
 
Test + HGH is a solid base. Mast = harder/drier look, more mental drive, but harsher on hair/prostate. Primo = mild, clean gains, good for long runs, less “pop” but easier to tolerate.

Both together would polish you up, but Primo is usually the safer long-term add, Mast shines if you’re already lean. Proviron isn’t oral Mast, similar family, different compound.
 
What sources are we looking at for Primo? I see Ace Labs has reviews on several items, but notably Primo has no reviews. I’d love to run this with my Test as the backbone of my first cycle, but, definitely wary of where to spend my money.
 
I don’t know what brewers do to screw up primo bc it’s very hit or miss when I use it as far as getting fevers/terrible pip. It’s been about 50/50 for me. When it’s good, I love it. I gave up though and switched to mast. I don’t carry a pump the same way but I feel good on mast.

@P.S.L. and AA Solution but that good primo that has been user tested.
 
I am one of those that aromatize easily. I have to be very careful with Primo because it will crush my E2 in a heartbeat.

What do you run it at for a ratio out of curiosity?

To give you an example, if I run 250 MG of Test on its own, my E2 is in the 120s, the same amount of Test with 100 MG of Primo drops my E2 down into the low teens, so I keep at a 3 to 1. 300mg Test and 100mg Primo and my E2 stays in the middle of the reference range 25-30.

I also mix my test in Primo and sterile, vile and do one injection, that really helps with the pip.

I’d start with a low does of Primo then get bloods done see how far your E2 drops everyone is different.

I have spoken to a few guys that have the same issue with Primo crushing their E2, they also aromatize easily so it makes me wonder if there’s a correlation.

Oh the good old Masteron and Primo questions. Both incredible compounds. I used both for decades and no wrong here. Don't expect massive gains. Slow, steady gains with minimal side effects. Dry compounds.

Have you used them together?

I might dabble, on a test primo cycle rn, gonna pull bloods to make sure I’m all good soon and due to this drought I won’t be able to get more primo anytime soon, so I want to add mast while I can.

If you can find real Primo and Mast, they do work great together. I’ve found running test/primo for 14-16 weeks and then adding in mast for the last four weeks of a growth phase works great.

Many times. Test/Mast/primo 300 each is a wonderful cycle

Mast great for stacking it with trt. Sex drive, dry no water retention, very minimal sides if any, if your body fat is low enough veins pop up like crazy. 200 test and 200 masteron is great, at least based on my experience.

Primo I feel like superman. Feeling of well being, everything that masteron does also round full muscle bellies. Gains are slow, steady and you will keep all of it when you stop.

30 years using gear I only had to use AI couple of times for few days. I have never used AI when either masteron or Primo are included in my cycle. This is all based on my personal experience so others my have different reactions .
 
Wiseguy said:
Understood. That is the reason I tell everyone before using an AI make sure to do your blood work. Masteron never had a significant effect on my E2 go figure, but Primo definitely does.

I remember I was on Test Primo and was fine. Added an equal amount of Mast and I flattened out and joint went to crap. We are all different enough to make it an a very personal experiment. Probably if I added an equal amount of test I would have done better. Now I'm just to old for the experiment.

For me mast is the icing on the cake, it's completely cosmetic nothing can give you that look like mast, it makes you feel great, that said primo comes close but builds muscle too (some feel better on primo others on mast)
Just take both

You are asking to kiss your hairline goodbye with using both, primo makes my hair fall out and so does masteron, primo fucks with my libido too and crashes estrogen , but it keeps my skin clean and keeps my emotions in check when on high test

If you blindfolded someone and didn't tell them they were getting Primo or Mast, the majority wouldn't be able to tell the difference. The significant difference is in estrogen management. Love both.

Is this from your experience with coaching guys who've ran both? Have you seen similar gains with both compounds? Mast is like the most polarizing compound there is. Most guys swear that it's not anabolic whatsoever and then there's a smaller percentage who just love the stuff. Makes me wonder if the vast majority who claim it's not anabolic at all are just comparing it to something like dbol or deca, both of which add scale weight much faster, but not necessarily more lean mass? Thoughts?

Mast is certainly anabolic. I find Primo is "slightly" more which is why I prefer it in a lean mass phase, BUT when primo is swapped out mg for mg in the same situation there is very little if any difference aside from a "slight" water drop.

Guys associate with sides with whether something is working or not which is f'ing dumb. Primo and Mast have very little if any sides and work in the background similar to anavar.

A test, Primo and/or mast cycle can be used in literally any sitaution.

Combing the two? Unless money or access are issues I prefer not combining. There really is no point running them together. People say the primo will help keep you full and the mast leaner...bullshit. This is after many years of using with clients and myself.

Just my 2 cents.

It's literally anabolic. Is as anabolic as Tren? No, but it's still increases anabolism .
 
Primo crushed my estrogen until I dialed in my ratio. 650 test and 400 primo had me hovering right around 21 E2. Mast didn’t do much of anything for my E2 level but increased my Free Test.
