What’s your experience with primo?

[maxrep24]

ive only ran primo a couple times and this was before the shortage, i still needed an ai on 2:1 test/primo, noticed i shed pretty bad on it, and the pip from 200mg/ml sucked. I much rather use EQ. It’s craaazy to me that people are paying $180 and up for a 10ml bottle.

How’d it affect your hematocrit? I’m running 750 test, 450 primo and 8iu Gh. Hemo is at 51%. Pretty steady, tested 4 weeks in

Not bad at all. Esp compared to deca or tren. I typically run higher end even when I had low test (like 47-50). I did 20ish weeks of 600 primo/500 test and usually 200mg of mast a few times. Never really got over 52/53 from memory.

Mine was 200mg/ml but nothing horrible. Felt it a bit but not major issue. I'll say this - if I had to use 100mg/ml I'd definitely not use it again. Way too much hassle.

The response to a given compound can vary wildly. Great if it works for you.

I personally think Arnold was full of shit when he said primo was his favorite compound. He was a serial bullshitter, he would say anything to get an edge over his peers (probably helped him later in life when he became a politician) He once told Oliva after beating him in a show that Oliva needed to come in fuller next time and that this would help him win. Serge came in fuller but sloppier and lost the next show.

I start to actually like primo(as an AI). Simply because I need to run it test/primo 10:1(yes 10:1) and it keeps my estrogen in range.

Mast makes me flat, eq has no AI effects for me. Primo NUKES my e2 so perfect for a high test cycle.

No experience but I want to try it sometime for sure to know why everyone rates it so highly.

I say that, but honestly. looking at the price of it … I will probably just keep going with EQ and put the extra money into more gh or better quality food or ten other things. Not like anyone ever needed this stuff to get big or in shape when there’s test, eq, nandrolone, tren mast and winstrol — but please, correct me if I’m wrong.

Too expensive

Primo is a good aromatase inhibitor.

Phenomenal additions to the conversation.

I will say that I’ve had a better experience with higher dosed EQ than primo. I do like it, but I also have not noticed the AI effect a lot seem to get. I also do not aromatize all that much though. Mg for mg (and $ for $) I’d take EQ. Especially nowadays. That said, I am sitting on a stockpile that I will use eventually once healthy again. I was so intrigued by the reviews on a certain sponsors acetate version that I bought quite a few. The price was unbeatable so why not. It’s just not some magical unicorn of a drug that people want to believe it is.

Ive used it 1:1 a few times with my trt nothing crazy as far as dose goes. I am a high aromatizer and it definitely has an AI effect for me. Ive done 8 weeks as high as 250 and feel like i saw saw more in my blood work than in the mirror. E2 was in check and hdl was in the high 20s. I have a vile of primo e on hand I may use just for the hell if it after my annual blood work the doctor orders in a few month.

I've used primo 1:1 on a trt dose and it had my e2 at 16..surprisingly my joints/mood felt good still.. I've crashed my e2 with aromasin before and my joints ached and cracked.. Not looking to replicate the experiment again but interesting observation I guess

I noticed the same with my joints. Not really aches at all. And I've also crashed my e2 on adex, like my report just said >5 .

Love test and primo. Fuller look. Strength is good. Mild AI effect. Helps immunity. I've gone as long as 11 months and blood looked great, felt great. It's not "the strongest" but it's the cleanest and most versatile from my experience.

Crank test and up: slow lean mass and strength, around 400-500 test and up to 500 primo was great, these were tested rimobolan amps years ago and very impressed.
More recently, long runs (6-10 mos) test at 250ish and primo at 100-200mg keeps estro where I need. The 11 months was 200-250 test/100-150 primo. Didn't impress me as much in the mirror obviously but felt great and blood work was spotless.

Been TRT only for 6-7 months... planning a moderate "blast"/cruise with test/primo only... trt test is 180mg weekly (60 mg 3x a week) will add primo 100/week for cruise portion and "blast" will simply be 300 test/200 primo.

I've been off here for months and seems several sponsors disappeared... and those remaining have had to crank pricing up. Will need to reload a bunch of primo asap so scouring posts for results/review posts... I've had primo that was EQ years ago and can't make that mistake again lol.

Care to elaborate on helps immunity? On page 1 someone mentioned this and I asked about it and they didn’t respond..

Well there isn't REAL testing data I can point to. Old animal studies and individuals repeating my experiences mostly.

High dose/strong androgens are typically shown to be immuno-suppressive ... Does not seem to be the case with moderate dosed primo. In my personal history I've never been sick while on primo and I've done several runs 6 mos... 8 mos... 11 mos... at least half the year on primo for the last 8-9 years. I've gotten sick weeks after stopping a few times. Coincidence? Maybe. But I somehow FEEL healthier on it also. Could be in my head but it seems moderate-dose methenolone may indirectly support immune resilience by improving recovery, reducing catabolic stress and modulating inflammatory signaling. There is little evidence to support this though.

Likely it's just that it's so mild that it does not negatively impact immunity like it would on virtually anything else.

Hits my bloods more than it alters my look.

Zero strength gain.

High RBC/HCT/Hgb

Low estrogen


Not worth it for me to run anymore. I’ve tried it with tons of different test doses and when you start getting to 10:1 what’s the point anymore.

Especially now that it’s pushing $200 a vial. Wasn’t worth it at 100, definitely not at 200.

I have no data but I've always heard primo being said to be immuno stimulator. I think deca too.

Per above poster stronger androgens I've heard similarly. Not sure I've noticed anything one way or other in life but who knows.

$200 for a vial...? Bro, someone's making a lot of money off you

$180-200 for 10ml is pretty common now for most US sources and it sells out within days

That is the first really good reason in this thread that would make me consider using it. I mean not missing out on 2-4 weeks a year on training and eating due to being sick would be big.

The topic of Primo comes up from time to time because for years, opinions have circulated that Primo works somewhat differently than most steroids, and many people claim that they get sick less often on it, recover better, and generally function more "stable."
Of course, there are no solid studies showing that Primobolan magically improves or boosts immunity, so I don't want to make it some kind of health product here, because it's still an AAS and still affects the body, lipids, etc. But the topic didn't come out of nowhere, as there are certain factors that may partially explain these observations.

First and foremost, most stronger drugs simply damage the body more. Tren, orals, high doses of testosterone, and 19-nors often worsen sleep, increase inflammation, overload the nervous system, deregulate blood pressure and blood glucose, and simply make people feel more "sick." Primo has been considered one of the cleanest drugs for years. It doesn't aromatize, doesn't increase inflammation, and actually reduces it. Many people experience a more stable mood and simply function more normally on it than, for example, on tren or orals.
And I believe this may be a large part of the answer. Primo doesn't so much improve immunity, but simply disrupts it less than many other agents. And that in itself makes a huge difference.

Interestingly, there are also old studies showing that different anabolic steroids can affect the immune system completely differently, and not all of them have the same immunosuppressive effect. Furthermore, Primobolan was once used medically for emaciation and anemia, so it's possible that this is partly where its "health-promoting" reputation in bodybuilding comes from.
Similar discussions have been held for years around Anadrol, which also had medical applications for seriously ill patients and problems with anemia and emaciation.

Honestly, I believe more that Primo is less disruptive to the body than most AAS, rather than directly boosting the immune system. But at the same time, I've heard this from many people over the years, and there may be something to it, especially when you compare how the body feels and functions on Primo versus, say, Tren or orals.
