I'm a test guy so primo is not my thing. I can accomplish just about anything I want physique wise with test only cycles as long as I get bloodtests and keep up with my ancillaries. I just manipulate my quanity, diet, cardio volume and intensity, weight training volume and intensity. But, and it's a big but, I have to keep close tabs on my BP, HR, prostate and cholesterol.
Nothing I know of comes without sides. I eat to damn much steak and my cholesterol goes up, I eat any salt added to my food or don't watch the salt content of packaged foods and my BP skyrockets. Too much test, my bp goes up and my prostate will enlarge. Too much test and not enough anti-e's and dick is not dependable. I'm sure primo has sides at certain dosages but I'm betting from what I'm told by some that are smarter than me that, in reasonable dosages primo has minimal sides. I don't have the experience to back that statement up personally but I have the experience of trusted training partners that leads me to believe that much of the low sides hype of primo is true. Until I have first hand knowledge to the contrary I'm believing those guys I trust and see almost everyday.
Guys I know that like primo like it because they claim sides like high bp and such are much easier to control at moderate doses of primo than they are at the same doses of test and they are willing to sacrifice size for health. These guys are 35 to 50, healthy and look solid because they are able to do a few cycles a year that are not very toxic or long term. I see their results all year long and they are undeniable, solid, strong for their size, cut up pretty good and lean (a bit too lean for me). For them it's a compromise. They want to be on several times a year because they can't achieve their look naturally. So, they do a moderate dose primo/var cycle a couple times a year and they get a compromise look and they sleep at night when it comes to their health. They also claim not to have any dick dysfunction. Now I don't know if I believe all of them and I really don't care. But why would they lie to me?
Everything fits a purpose and when one of my bros says I'm goin on primo/var cycle I might be thinking bitch cycle but I'm saying go for it bro. I like to keep my friends and don't want my next sentence to come out of my mouth while I'm on my back.
When I was 25 I wanted to be 5"8" and 235lbs with 10% BF. If I couldn't push the weight or gain the size I wanted to back then I'm the kind of guy who would push the test to 1000mg/wk deca to 800 mg/wk started the anadrol at 75 mg/day and by wk 3 I'd be at 100mg/day. That's if I could get all that and ancillaries were a necessary evil that I never got enough of. I'm twice that age now and I've gotten smarter about dosage and I'm realistic about goals. A solid 5'7" (I shrunk an inch) 195-200 lbs dry and solid is doable and I stay reasonably healthier. I determine my BF by using a mirror.
To each his own I do my thing and some of my bros do a different thing it happens to involve primo and they justify the cost with better health and fewer sides. I believe there health is generally better than mine as we will occasionally compare numbers. My health is pretty damn good but it could be better. But I'm a test freak. Test gets me feeling much younger than my years. It's the balls to be older and almost as strong as I was when I was 35 and just as confident and cocky as I was when I was 25.
Just my longwinded .02. BTW I see plenty of guys, of all ages, at the gym who don't juice who could make some hair transplant surgeon a rich man.
