^^^ yeah exactly. there is a downside to everything. a newb won't like the high molecular weight of primo and its 100/ml heavy injections using a 22G needle.. ouch.
i actually think a great first cycle is 4 weeks of 30mg dbol stacked with 50mg proviron, its not an injectable like what the OP wants but it is a guaranteed winner or you can just grab a bottle of beastdrol (a buddy of mine runs a cycle a couple times per year and always raves about beastdrol, its all he runs) run it at just 20mg a day with n2guard and the sides won't be bad at all
