No need to run that much primo for a cutting cycle. Cutting comes down to diet, not steroids. They are not fat burners. If you want to run steroids, just do a low dose of test and focus on diet/training.
You are way too small to be using steroids man. I would focus on diet and add a bunch of muscle naturally first. You have an easy 20-40lbs to add to your frame.
It is so awesome to hear that the community is what pushed you over the edge to commit to competing. This is what it is built for......supporting each other. I can bet that your logs will do the same for multiple other people!!! Happy birthday broski!
