Lowest efficacious dose of primobolan

I’ve been scouring these forums and many others for well over a decade now and I’m pleased to (generally) see a trend towards more intelligent, conservative dosing with many different compounds. I just wanted to get an overall idea what your own personal opinion is as it pertains to the lowest efficacious dose of primo in a very basic test/primo cycle?

Example:
325mg Test-C / week
400mg primo / week

I know from experience personal makeup, diet, exercise regiment, sleep, genetics, etc are all massive factors that’ll skew the data…. But I used to see guys on here constantly saying you need 800-1gram of methenolone (primo) IDEALLY, and maybe a minimum of 500-600mg to see any results AND it needs to be run a minimum of 12 weeks, 14 if possible.

I see much lower dosages purported to give good results nowadays. What’s your experience been like when primo is the main AAS in your cycle?
 
I'd say primo is very comparable to masteron not only for the cosmetic effects and gains, but also with the recommended dosages varying a ton. Like you said some people run it at 200mg on cruises, some recommend much higher dosages on blasts, but I think the dosage you laid out of 400mg/week looks solid with that test dosage (could you get better results at 600mg? Absolutely. But to say you'd get no benefit at 400mg would be false). I think the primo sweet spot is somewhere between 400-800mg/week personally, but this also depends on how much test you're running as well.

It's been a while since I've ran primo, mostly because I can get better efficiency/$ with other gear, but I'll be adding it to my next blast. I'm all about the feel-good cycles now. Currently running test/mast/var, then I'll cruise for 10 weeks, then probably do a test/primo/var cycle, with maybe a splash of masteron again (but I'm not sure If the mast+primo will dry me out too much, stil reading up on this)

I’ve continued to see solid results with my primo at 300mg/week and test 600mg(along with other compounds). While that Primo dose is generally considered low I can say the 2:1 Test/Primo ratio has worked extremely well for me but as you mentioned there are many variables that play an role and everyone is different. In the end I think it takes a little experimenting to dial in the most efficient and effective primo dose for you. It’s important to find the right primo dosage and maximize efficacy given the higher cost compared to other available compounds. But more does not necessarily mean better. I buy a higher concentration primo because it makes easier to pin less volume and Primo has far more injection site pain/soreness

I went as high as 600mg Primo but after trial and error I found that 300mg/wk turned out to be ideal cruise for me.

I wish I found this to be true in my experience but unfortunately it's not the case. For me, at an equal dose primo yields much better gains but with that comes a whole lot more injection site soreness

Same here! Solid primo is at the top of my list despite being a literal pain in the ass.

Yeah I mean it is technically stronger than masteron, I just found Primo to be a bit underwhelming when I ran it, but I also don't think I ran it high enough, or I was getting some underdosed stuff, which is why I'd like to try it again next cycle at a higher dose to atleast get a better idea.

Primo:
"It possesses an anabolic rating of 88, while Testosterone’s anabolic strength rating is 100 – this demonstrates Primobolan’s fairly weak strength in terms of anabolic capabilities. The same holds true for its androgenic strength rating, which is approximately 44 – 57 in comparison with Testosterone’s androgenic rating of 100."

Masteron:
"Its anabolic strength is generally regarded as moderate at best (anabolic rating of 62 – 130), while its androgenic strength is fairly low (25 – 40)."
 
Primobolan would be amazing, but it's not for the reasons:
1. Expensive.
2. Mg/ml concentration is only 100, so adds up quickly.
 
Allows you to run more test and more accurately dial in E2.
But I used to see guys on here constantly saying you need 800-1gram of methenolone (primo) IDEALLY, and maybe a minimum of 500-600mg to see any results AND it needs to be run a minimum of 12 weeks, 14 if possible.
Read between the lines. They're really saying you need to run 1-2 grams of test to optimally build tissue. The primo is to control test sides.

Yeah the 100mg sucks means more oil/injection to reach doses, I know a few ugl that have it at 150 and 200 but they charge a arm and leg compared to other Compounds
 
I asked this question about a week or two ago and got mixed answers so I just decided to find out for myself.

I personally feel that different people respond to different steroids and steroid dosages differently. This isn't science based but my personal thoughts.

So run it yourself and see if it benefits you. I've read some people responding great to just 200 test 100 primo, While others claim that they only see primo effective at 700+
 
I've ran lower doses of primo on and off, fourth cycle here now. Keeping me super lean and loving it.
I paired primo 1:1 with test at 200mg/wk for 8 weeks and ramped to 250mg/wk for 8 weeks. I'm getting older and am a little scared of higher doses of test for BP.
With diet dialled in like an absolute psycho and zero alcohol I was able to get to where I thought I'd be first cycle and maintain abbs year round since.
This next pct I'm thinking of cruising with 75mg/wk, though still have to read more about that yet and have a month to make a decision.

Primo E at 200mg/ml, solves all those issues other than the $ problem.
For me personally, primo has not given me any pip in either the acetate or enanthate preparation, but then again, for me anything brewed properly in standard concentrations in MCT doesnt give me any pip.

as for minimum effective dose, ive ran as low as 350 on blasts, or 100 on cruise, and id call both effective anecdotally.
 
No, primo is primo. Bayer primo is no different than primo from any other UGL
Well one would hope but I wouldnt be so sure. There are about 10 or so large scale producers of raws. It’s synthetic and one of the more elaborate, time-consuming and expensive AAS substances to produce hence the higher cost. I’ve gotten BAD primo raw before, traced back to error in manufacturing process. Although I will say there are a fair number of UGLs on here that make some high quality Primo! Love that stuff.

so you:

1 ordered raws from some distributer
2 brewed it and found it to be bad from pip
3 somehow managed to get your distributer to tell you who and where manufactured it
4 you called up that manufacturer in perfect Chinese, and asked them "hey i bought this steroid powder from a guy who got it from a guy who got it from you, did you guys mess it up"
5 they told you, "yup, sorry man, forgot the tequilla, your next marg is on the house"

not calling you a liar, but if that order of events went down even remotely similar to how i outlined it its pretty unbelievable.

God if this isn’t the truth. I always opt for the 100mg/ml because the 200 sounds like it necessitates some solvent utilization and I don’t want the synthetic shit & systemic inflammation etc etc and have to pull bloods and include C-reactive protein to make sure and pay for that etc…. Awful big depot’s of oil and multiple injections though, my gawd…
 
I have added 100mg of primo to mty100mg of TC that i take for TRT and my Dr and others comment that i must be working out more.
Haha that’s excellent! Awesome to hear from a mega veteran such as yourself brother. Much respect & thanks

Hell yea it adds up quickly. Monetarily and in my ass cheeks. Some of those primo depot’s just sitting in my body waiting to disseminate make a muthafucka so sore dude
