    Primo-A vs. Mast-P

    Looking for any feedback on these compounds as far as cutting ability and lean muscle production. I know primo is the most expensive and a high dosage is needed, as for mast is relatively cheaper and seen some guys cut up with Mast. Just wondering if any one has tried both compounds and what results where seen? Is primo worth the high prices and high doses?

    I've used both, twice now. I used to be a big proponent of Primo but mast is more cost effective at lower doses. Both require a body fat close to 12% to yield the greatest effects. A concern with mast is that it's a DHT compound and increases your risk for prostate enlargement. You'll need to keep an eye on that and watch for symptoms of prostate enlargement as this can lead to a number of secondary problems and risks.

    Mast is great for getting that grainy look.

    What's the lowest doses you guys have used to get results? 600mgs of each?

    400mg/wk primo was ok. Improved vascularity but not as much as I expected. 600mg was better for a harder, leaner look. 800mg/wk was sort of the sweet spot for me (I bumped my 600 mid cycle) but that started causing some prostate issues.

    I saw better results at 450mg/wk with mast. Vascularity was superior compared to primo at 600-800 but I was also leaner when I started mast (11.8% vs 16.3% mast/primo, respectively).

    Right now I'm around 13% approx? not far off from my picture/avatar. How long were you on mast? Primo?

    I always run 12-16 wk cycles with long esters.

    You're welcome. Yes, it (primo) gets more hype than it should. It's not a bad compound but having used both, I'm sold on mast from here on out.

    I usually only run mast for 4 week at the end of a prep just to get that finishing look

    Yes sir. Like AShop, I know guys that run it for 6 weeks or less. I really like the longer cycle and the vascularity is reinforcing. I usually find by week 10, there may be voiding (peeing) issues if your sensitive to DHT and prostate enlargement. I usually increase my cialis form 10mg daily to 15-20mg/day around week 8 or 9 on mast and run it at that level until end of cycle or as symptoms necessitate. Only issue I've had with 15mg and above are infrequent headaches. Worse with 20mg; 15mg is less of a problem.

    I have been getting headaches lately, so maybe the mast is the culprit.

    He's saying the higher dose of cialis gave him headaches.
