Primo at 400mg for the last 3 blasts, was the price actually worth what it delivered for me?

Primo is on my list once I have more cycles behind me. The no-AI benefit appeals to me specifically - managing estradiol has been the hardest part of learning this. A compound that naturally controls it without needing to dial in an AI protocol sounds like a worthwhile investment even at current prices.

Primo at 400mg is correct minimum dosing. My experience over three blasts: 300mg produced essentially no measurable effect on body composition versus test alone. At 500mg the difference was clear and the bloodwork confirmed what the mirror showed - E2 controlled without AI, leaner harder look. The price increase since the raw ban has unfortunately pushed it out of reach for regular use.

Primo at proper doses is the most underappreciated compound in the community. The reason it has a bad reputation is guys running 200mg thinking they will see results. You will not. 500mg minimum for a male, 600-700 if you are serious. The raw ban pricing is the only legitimate argument against it right now.

Primo and mast together is the premium lean stack. Expensive but the quality of the physique change is different to any wet bulk. The combination keeps E2 in check naturally, stays dry, and the muscle you build has good retention post cycle. Just needs budget and patience.

Primo is the compound closest to my preferred aesthetic approach. Clean, dry, no aromatisation. The price is the only objection. I ran it for one cycle at 350mg and the quality of the physique change was unlike anything from a wet bulk. Saving for another primo cycle next year - worth planning the budget around.

Primo is the best compound nobody can afford anymore. Ran it at 600mg two years ago before the raw ban hit hard. Dry hard muscle, zero water, kept most of it after. Would love to run it again but at current prices it is hard to justify when more test gives a similar lean bulk at a fraction of the cost.

Primo is the compound I keep coming back to even at current prices. Running it right now at 400mg with test 350. The body composition change is different to anything else I have run. Drier and harder without the aggression or lipid hit you get from harsher compounds.

Primo is worth every cent when you can get legit product. Ran it at 500mg for 14 weeks two years back and the quality of muscle added was different to anything from a wet bulk. With the raw ban hitting primo hardest I have shifted to EQ for the volume work and keeping primo for the final 10 weeks of a prep.

My Primo bloodwork at 400mg showed E2 at 28 pg/ml without any AI, down from 41 pg/ml on the same test dose without Primo. The anti-estrogenic mechanism is measurable in blood, not just anecdotal. SHBG was also elevated which reduced free test slightly - worth accounting for when planning the dose.

Primo is on my list for a future cycle once I have a few more blasts under my belt. The no-AI aspect is appealing to me since dialing in aromatase inhibitors has been the hardest part of learning this. A compound that manages E2 naturally sounds worth the extra cost.

Primo at 400mg is the minimum. Ran 300mg on my first primo blast and felt absolutely nothing. Doubled it the following blast and the difference was clear - harder dryer muscle, no AI needed. The price is eye-watering now with the raw ban but for a 12 week lean bulk the quality gains justify it if you can verify the source.

Run primo at 400mg a week across my last three blasts now and figured it was worth a frank writeup given how much the price has climbed. The honest truth is primo does not put scale weight on the bar, anyone chasing numbers on a wet bulk will be let down. What it does give is hard dry muscle quality, no water and no bloat, and that clean look holds well after because there is nothing to drop when you come off. At 400mg it is a real working dose, the guys running 200 to 300 and saying they feel nothing are just dosing it too low. The question I keep coming back to is whether that aesthetic is still worth what they are asking for a vial in 2026, because the methenolone raw cost has got silly. Keen to hear from anyone else running it properly what you reckon.

400 is the floor, anyone telling you they felt something at 200 to 300 is kidding themselves, the compound is too mild to register below that. At 400 it gives that dry hard quality look on a test base, no water and no real scale weight, the mirror is where you see it not the bar. The problem now is purely the price, sitting north of 120 a vial since the raw situation and you need two vials a week to run it properly. For a lean bulk or off season hold it earns its place, but if you cannot verify the source you are paying primo money for oil with a bit of test in it.

Primo earns its place if you can source it real, the issue has always been cost and fakes, not the compound itself. 400 a week minimum or you wont feel it doing much. Best run in a lean bulk on a test base, anyone running it on a wet bulk is wasting good money.

The threshold point is well made. Members who run 200-300mg Primo and feel nothing almost always conclude the gear is fake when really the dose is just too low to move the needle. At 400mg you are in the working range. The price per vial right now makes that a significant weekly cost, which is why fewer people are running it properly.

Where it earns its money for me is the lean hold and off season work. Paired with a moderate test base you stay dry and add actual quality tissue rather than a water balloon. The aesthetic is the payoff, not the scale weight, and if you understand that going in you will use it correctly. Running it into a sloppy wet bulk just wastes the compound and the money.

The threshold dose thing is real. Ran 300mg twice and felt absolutely nothing, convinced I had bunk gear. Third time at 400mg alongside 500mg test and the difference showed up around week 6 - slower than anything else but the quality was there. Problem now is the price makes it hard to justify unless you have a solid source you trust.

This is exactly why I stopped pushing primo on anyone watching their budget. At 400 it does what it says, dry quality tissue, no bloat, estrogen stays controlled without me touching the AI much, but you are paying test money several times over for the privilege. The trap I keep seeing is guys running 200 to 300 convinced they got fake gear when really they just dosed too low to feel a thing. If you can afford the 2 vials a week and you run it in a lean bulk on a solid test base it earns its keep. Outside that case I would honestly put the cash into more test or EQ and just accept the wetter look.

Prefer to have higher estrogen, the look (slightly fuller as I can get stringy) the libido and the mental clarity. Sadly I was never that impressed with primo, would rather use test NPP and mast

Primo does one thing really well and that's dry quality tissue with almost no sides, but it was never going to put scale weight on you the way test or deca does, the look is the payoff not the bar. The 400 floor is real too, every time I see someone running 200 to 300 swearing they got fake gear it turns out it was just dosed too low to feel anything. At 120 a vial now with the raw ban it's a luxury compound, it earns its money on a lean bulk paired with a test base where staying dry matters, run it on a wet bulk and you've thrown the cash away. Bloods are the only way to actually know it's real, methenolone is one of the most counterfeited compounds out there precisely because the price draws the scammers.
