Being a newbie and knowing that testosterone is the father of all gains, what would happen if I went on a testosterone cycle only. I do have access to Deca 150 mg/ml and Trenbolone Acetate 75mg/ml but for a first cycle someone mentioned a Test only cycle first. I have access to Testosterone phenylproprionate 150mg/ml and injectable Dianabol 50mg/ml but due to limited funds I cant do aheavy cycle just yet and yes I have covered the PCT. Already have kids small testicle not a major problem but being a male would certainly like them to be normal

Advice on how much to use to make gains not necessarily huge, how often and any other info. Is it worth trying to get some Test Cyp?
Thanks for any help
