What’s your experience with primo?

[Eddie.]

I like primo but honestly I’m not seeing any legit reason to run it if you’re not a competitive bber or a rich person. The cost adds up like running a good amount of HGH. Also, I hate the pip and oil volume.

It doesn’t bulge my bloodwork much but I’m on ancillaries (like rosuvostatin and ezetimibe) year round so that doesn’t bother me much.

One weird thing I’ve noticed with primo is that every time I throw it in, for the first 5-6 weeks it tanks my libido even with e2 in check. Then something swaps and I’m all horny. In my current cut that I’m running I was with EQ, I had 3 bottles of primo left and decided to swap EQ for last 2 months to see if there’s any difference. Fullness is good but it tanked my libido again. Now I switched back to EQ and saved my ass some pip, some extra shots from the lower volume and obviously money.

If I had to push higher dosages and had the funds I’d probably prefer it year round as a healthier compound instead of EQ but since both reduce a ton my estrogen levels I only need 300 primo with 800 test or 200 EQ with 800 test to have a ~40 estradiol with no AI. So there’s that.

On the other hand i can’t imagine myself pinning absurd amounts of oil with 100mg/ml while I can use pip free EQ at 500mg/ml.

Primo hits my libido as well. E2 not crashed (lcms) , in zone where I normally feel great. Not bad just a meh. Every run is like this and I have a number now. 200mg of mast added in does the trick for me. Really makes a difference here for me moreso than others.

I feel like if it hadn't been discussed so much by certain social media figures in the recent past we would not be talking about it nearly as often.

All these AAS have been around for ever. There is nothing new under the sun.

The whole "influencer" side of things has destroyed alot for the bodybuilders...

And that in itself is a broad spectrum. From "science bros" to "all the gear at 16" and everything in between.

While on the treadmill today I watched Lyle McDonald on one of his rants. Classic.

Its sad i hate it so much, Lyle blocked me years ago, what was he saying ?

Going off on a fitness influencer for not understand what "maintenace calories" means in a scientific sense. E.g. she claimed surplus is only fat and muscle and stored glycogen cannot be counted as energy reserves.
I first chatted with Lyle on USENET 30+ years ago.

Good Lord, Lyle has always been "vocal" and sometimes a bit to vocal imo, but i get why he goes off the amount of BS he must see and "disprove" in his line of work, that would drive me insane.

VG Steve is to blame for a LOT of bullshit being spewed even with the CONTEXT of people strictly wanting to use gear naked. Biggest PED creator in like 2018-2021

 

[Testabolin]

I have to run test much higher. I am not an aromitizer, and can run 1g of test with no AI. If I add primo its at a 3rd my dose of test, else my e2 tanks. I don't have as much a problem with mast.

wanting to use gear to look good naked* big typo lol

How much primo do you guys need minimum to get the 'look' out of it?

Seems people start noticing results in the 100-800 mg/week range.

The same - although I have never used less than 300mg, I have been using primo since 2024 with breaks in doses between 300-1400mg per week - currently I am on 300mg and I still see its benefits

I've made all my progress the last two years on test and primo. Everyone shits on it continuously, and it makes me laugh. I can run high doses and have great bloodwork except for low HDL. No negative side effects. Makes me full, dry, vascular. I bought into the EQ hype recently and tried replacing my primo with it. Nothing but issues since I did that. I guess I got lucky and found what works best for me early.

I think it's the perfect drug for growth since you can run high doses with no sides for longer periods.

What is ‘high’ for you?

 

[Oakley6575]

What is ‘high’ for you?

I have to keep my primo dose at 40% of my test dose for my E2 to be in the 30-35 range. So the highest I've run is 1500 test 600 primo.

This 100%. We always hear how certain compounds like mast or primo provide “cosmetic effects” only. I mean sure, something like mast provides a nice cosmetic effect…however, the same argument can be made for nandrolone/tren/dbol. Nandrolone also provides a cosmetic effect of someone looking much bigger than they really are due to water retention in all the right places (which may be where the idea of it gaining “more muscle” could originate). For me personally, that similar cosmetic effect goes away within weeks of removal of that compound (and all that “muscle” I thought I gained was mostly water).

Npp/tren maybe can add more muscle to someone’s frame but it doesn’t matter if you can only use it for 4 weeks due to how much it is impacting your health. Real muscle is built over months and years, not just one cycle or 4 weeks.

I don’t think you can look at certain elite physiques and say, “oh yeah, that’s a nandrolone-built physique” vs someone who used test/primo or test/mast. Jacked is jacked.

I think what separates bodybuilders from wannabes is the diet, training, and anabolic use consistency over time more so than the exact compounds used. Too many variables in each and every one of our journeys to make the blanket statement that specific compounds DON’T build muscle compared to others.

I believe the true goal is to use compounds that allow you to stay in an “anabolic surplus” for as long as possible without negatively affecting your labs, blood pressure, sleep, mental, and resting heart rate. If that’s test/primo, test/mast, or test/nand, then that is what is best for YOU to get and stay jacked over the long term.

Sometimes people just need to experiment for themselves over 4-12 weeks to see the short-term negatives of the compounds they take so that it can be quickly ruled out and they can quickly pivot to a stack they can stay on long-term to stay as healthy as we can be for as long as possible on compounds that our body is not fighting against.

I'm not directing this at you necessarily, but your post allows me to make a point.

Low HDL is the primary short term side effect of injectable AAS. It's a key characteristic of injectables that cannot aromatize.

To say we aren't getting any sides - aside from the most significant and perhaps dangerous one - seems....odd.

I won't shit on primo per say, but when I see people saying it's "safer" than a comparable AAS so they will take 3x the dose to get similar results the relative health profile has gone out the window a while ago.

Reminds me of people who insist on taking 100mg of Anavar because it's "safer".
