Primo is one of those steroids where some people just don't see the value in it. It's very expensive for the price. I would switch to Equipoise to be honest.
Superdrol is a very toxic oral steroid. I would not run it for more than three or four weeks. You can do 10 to 20 mg a day and you'll get perfect results.
Reta is one of the best things out there for fat loss. You want to take full advantage of it. Make sure you are eating great on it and you're exercising.
Reta is going to cause some side effects in the first 4-6 weeks. Once you get past that point, you can gradually start increasing the dosage and you'll be able to get away with it.
