Yes, and yes.
Love primo and has provided solid, quality gains that stay for me. It is slower and requires more volume, but hands down favorite. I run with Mast, typical spring cycle is test 400-700/ primo 800/ mast 400. Feel amazing entire time (do get tired of all the pinning by end) and simply works. I get no noticeable sides and run 16-20weeks. I will sometimes add in var for 6 weeks somewhere along the cycle—which will give me some sides seen in my lipid profile and muscle pumps. Primo/mast/var gives me wicked pumps, and have to slam a ton of water or go directly from pumps to cramps.
I personally view my results from primo as more solid and aesthetically appealing than anything else I’ve run except maybe tren. Newer to tren and results have been amazing, so see why folks run it, but also comes with additional costs. I only have a short time each year I can suffer the cardio impact, and both it and NPP makes me feel lethargic and typical heartburn/sleep issues suck. For me, if I had to choose only one compound to run with test and that was it, now and forever, it would be primo without a doubt.
I personally prefer Pcom’s primo great primo since It’s 200mg and all testing I’ve seen (anabolic labs) has been on point. It has a higher EO content I believe, but I don’t have reaction to EO so perfect for me. If EO sensitive, I’d suggest trying another lab. Other thing is Pcom’s cost for their 200mg which is ridiculously high compared to other UGL, but always proven worth it to me. I don’t mind spending more for peace of mind that what I am running is legit and sterile.
if looking to run lower dose, one of the sources here on Meso has 150mg primo E that doesn’t have EO, uses GSO as carrier and have run it a few times. Was on point in my experience, and hellova bargain at his price. I liked it enough that I recently grabbed more.
