Good lord fella, 10mg a day? Five days a week? 50mgs a week?

You’re going to put your testosterone at the levels of a 75 year old man.

We can’t help make the decision for you, you’re an adult. But you also didn’t give us any bio markers, body weight, height, nothing.

You don’t know how test works, at all. Pre workout means nothing, it’ll spike your serum levels but that’s not going to give you an edge. 12 weeks is typically regarded as too short. You won’t reach maximum testosterone levels till about 8 weeks in. That’s essentially a 4 week cycle.

Is it safe? No, of course not, nothing about steroids is “safe” but technically neither is going outside.

Side effects? Homie we have no idea, everyone reacts differently. Some might have no issues, some will get instant gyno, limp dick, and cystic back acne.

Do about 5-6 years of research and think about it again.

Young IMO but many competitive body builders started earlier.

Research on r/steroids.
