Blasting and Cruising is indeed healthier and safer for your body then cycling. When you come off gear and go into pct, your body is shocked with various drugs (Hcg, clomid etc.) to restart its natural hormonal process, this is hell on your body as it doesn't want to change, it wants to stay the same. Your body is working its arse off to try get your hormones at a stable level which could take awhile, and your hormones will most likely never be optimally good again unless you do something like one or two moderate cycles and leave it at that for the rest of your life, but it would take a few years. An example of this is chestbrah, Aziz's, also known as "zyzz" brother use to use steroids. After being caught fined and discontinued his use he got very small. But if you take a look at him now, he's shredded and has gained..so he has recovered over a number of years. Wether he still uses is unknown, but seeing as he competed in a few drug tested fitness model comps I pretty sure he is.
Blasting and Cruising has more pros then cons if you do it RIGHT. A cruise is not a stack of compounds together ran at mild dosages..its a time were you give your body synthetic testosterone at a dosage let's say 100-200 mg a week, what it produce naturally. Now after blasting, this does allow the body to have a break and recover..and your body will not have to deal with the stress of trying to stabilise its natural production. You will retain most, if not all your gains from your blast as long as you continue to have a good diet and training program obviously. The cons are somewhat to think about though: Increased chance of heart attack or stroke, increased cholesterol & blood pressure, more side effects depending on the person. And the chance of your natural hormones ever coming back gets slimmer and slimmer.
My opinion is, if you know you're going to be using anabolic steroids for awhile, it might be worth your wild blasting and cruising. You will also not have to play catch up every time you hop back on, as we all know most of your gains will disappear post cycle. I believe with a good diet, a trusted doctor who you can see on a monthly basis to get your bloods done, and reasonable dosages in both the blast and cruise that it is a much better option to go rather than cycling. Saying that, if you have a family, or plan on having one, it might not be a good idea. Also, if you're not financially stable enough to fund for your goods then you'll just lead yourself into a whole of no money. Sit down and make an informed decision and ask if you're ready to make this commitment and next step in you're life. Not someone else's, YOUR decision. And if you have a wife or loved one you live with, don't try hide it from them.
It's a life decision that will either make you or break you. If anyone's thinking about doing it I hope this might've helped.
