I have heard from others on this forum that gear such as Sustanon needs to be injected at least twice a week because it has a 3-4 day half-life. On my first cycle, I injected once a week (every Sunday) and I made great gains. (I was also stacking with Deca-Durabolin and Dianabol (tabs)).
Is it reliable to make gains from injecting once a week?
How about Deca?
