What’s your experience with primo?

Just wanted to say thank you to everyone who replied. The information has been invaluable and I’ve concluded after trying a few compounds over the last year that I really enjoy primo and its results and low side effect on my bloodwork. Seems like the 60%-70% of test dose for me works like a charm for my estrogen and lipid effect is minimal. Next blast is going to be 1200 test 750 primo and see where that takes me. Going into a lean phase next. Might throw in some mast towards the end. GH @ 6iu/ed on top and I’m feeling like the king of the world rn
 
Masteron is also okay in my opinion, but it has a much greater impact on health parameters than Primo.

I choose Primo as something I use for most of the year.

What parameters do you think Masteron is harsher on compared to Primo? I'm asking because a few months ago, I ran testosterone and Primo for several weeks, and my labs looked good. I then swapped Primo for Masteron at the same dose, and my follow-up labs were very similar to what they were on testosterone and Primo at the same dosages.

In my case, Masteron didn't seem to negatively impact my labs any more than Primo did.
 
It's not. If side effects bothered me less, I'd just run 2g Test and an AI - which would still be much more water retentive even with equal e2 compared to test / primo.

But I like feeling good, and I'll take 80% of the growth while feeling good any day.
Did you try the 2g test + AI? I tried 2g test+AI by itself and 1gr test 1gr eq for example and hardly notice a difference in look.

To be fair, no. I've taken test to 1500 for very brief periods and have stayed at 1200 for extended periods. In any case, it does feel like regardless of e2, there's more water.

It still affects the RAAS independently of estrogen, but the magnitude of that effect probably varies. I tend to be very water retentive.

If you dont grow on that stack your problem is not the primo ;)

You know, I think that in the short term the differences between Primo and Mast probably won't be very significant when it comes to bloodwork. And honestly, I'm not even talking mainly about blood markers here, because that is very individual anyway.
I think the impact on bloodwork would be fairly similar with both Primo and Mast, and the difference probably wouldn't be huge.

However, this is just my opinion, but I believe the higher androgenic nature of Masteron may have a more negative effect on the body over time, even if standard blood markers don't show it. What I mean is mainly increased oxidative stress.
In my experience, and based on what I've observed over the years, more androgenic compounds tend to increase oxidative stress to a greater extent.
More anabolic compounds seem to do this to a much lesser degree.

That's only my theory and it's also what I've personally observed over many years of using and watching these compounds in practice.

Thanks, luki for sharing your opinion. I had never thought about that, but that actually would make sense, and it may be something to think about long term when choosing these compounds. I'm glad you brought it up.
 
I've only tried Primo twice at a dose too low to be worth it so I can't really comment on how well it works. What I did notice, whether coincidence or not, is that when I did Primo, I'd reaggreavte disc issues in my back. I don't know for sure if Primo actually had any correlation but the coincidence was enough for me to stop experimenting with it
 
I've used primo a few ties for contest prep and noticed good results, but It tends to be way overpriced and later on in y bodybuilding career I switched to Masteron and found the effect to be very similar but the overall cost was uch less expensive.
 
I'll be the contrarian here.

I think Primo is overpriced and over hyped.
I used it way back in 89-90 when amps where easy to get, along with Parabolan. I tried it again a few years ago. Not impressed at all.

Nothing unique in my experience despite what others have reported. Maybe I'm the outlier - after all I'm the guy that likes nandrolone more than test.

It's relatively weak per ml, so unless you use large doses, which I am not fond of in general, you're not going to get much.

If a client has used it and liked it I won't dissuade them, but I don't use it.
your not alone my friend. masteron was equally effective to primo during prep and given that fact I stopped primo completely and switched to prep with masteron and a great side effect I saved a shit ton of oney which I then used for gh.
 
currently doing a low dose course. Been training over 30 years and have a lot of muscle built so doing 200mg Primo with 250mg Test e E5D and so far, the gains are solid. 8 weeks in test dose is helping me with more energy etc and the primo is helping to bring out the shape of my muscles planning on running this course for 16 weeks.
 
Loving primo. Currently running 600 test cyp 600 primo and 6iu gh

night and day difference from my test and mast cycle. Much better size and fullness. Strength and overall feeling. As well as libido. Would definitely use again.

Pip is an annoying but manageable.
Personally home brewed my own 200mg/ml in Mct. 25% bb 1% ba.
I split it 0.5ml primo and 0.5ml test cyp in same syringe heat and mix and that alleviates most of the pip. That concentration injected on its own causes way too much pain.

Yes.. I feel that mast is much " harsher" over time.. of course dose dependent. My bloods running test cyp at 425mg and mast at 300mgs had no effect on my e2 levels at all.. but diffinitely " hid" any estrogen sides for the most part.. when i eliminated mast.. waited 4 weeks to add primo at 300mg and then ran bloods 5 weeks later the primo ran down my e2 pretty quick.. by half.. but oddly enough lipids were roughly the same .. the difference in how I felt was a bit more apparent.. i felt a bit worse on mast.. just a general feeling that I didnt want to run it very long.. primo I felt great. . The good feeling on mast lasted about 4 weeks before I felt a bit off.. the great feeling on primo was constant.. so its anecdotal at best.. but many feel that mast hits them the same way.. just a bit more " toxic" over time..

Same here. PiP can be a bit of a bitch sometime but I heat the vial on a coffee mug warmer first and it help quite a bit. Currently at 750 test, 600 primo. Doesn’t crash my estrogen so much and I feel better at this ratio

Agreed I always warm mine and mix it as well as I can with my test in the barrel so far it’s been like 1 out of every 10-12 shots more inflamed then others but for the most part the daily shots going well

Same, every now and then I get the peg leg butt but usually no prob. There’s an art to it, I’m running a 150mg/ml solution too. Easier with 100mg/ml. Glad I never got any 200’s haha
 
I’ve been running 450 primo, 750 test, and 10iu GH for a few months now and have had tremendous results. Pip is a bitch sometimes but the 150mg solution is tolerable. Whats your two sense on primo, pip, and dosages. Just did bloods and I’m lookin solid. Going to continue blast. Everything in normal range, 51 hematocrit, 580 igf-1, 2337 total test.
If you have the patience to wait for the results in the long run , it is a mildly ok compound . If you want fast results like me , any compound except for trenbolone , winny , gh + slin , superdrol , anadrol is overhyped and weak . Primo , npp , boldenone never gave me any jaw dropping results . Testosterone is another category obviously as it is the base of each cycle . I would use primo to maintain my muscle mass between my actual cycles with the compounds stated above . Or use it as a 3 rd compound to get the mgs up in a cycle .
 
Everyone responds to things differently, same with Primo. We are in a world where everyone wants things instantly. Primo isn't like that. We gauge a lot of our anabolics off of 'feel' and side effects and Primo is something that has minimal sides if any and you really don't feel like your on anything, results are slow and subtle. Another factor is a lot of people really haven't used Primo. It's faked a lot so u might have been injecting just oil or something else entirely.
 
Primo is extremely expensive right now per kg so be cautious when buying. I like primo but I don't think it is anything special. It's a great compound but taking everything into consideration there are better options. If you love it then go for it because it can be a great compliment to test and for many you won't need to use an AI whilst combining both. At the same time you need a decent dose to get noticeable results so if you have even a medium budget it's a no go. Granted mast is expensive as well but nowhere as much as primo. Then you have the likes of bold 300 or deca 300. If you are a beg/int with some sort of budget just go with test and deca/npp/bold/mast. For the more advanced guys who know their response they might want to pay out for it because of it's various attributes and minimum side effects.

Sounds like it’s treating you well. If bloodwork and BP are staying in check and you’re not dealing with high E2, Primo can be a great addition. The PIP at 150 mg/mL is pretty common, but rotating injection sites and warming the oil can help. Just keep monitoring hematocrit and lipids if you’re planning to stay on a long blast.
