Honestly, at your age and body fat you shouldn't be using steroids at all. But I know you will do it anyway because nobody ever listens once they have their mind set on it.
The dosing isn't bad. I like 300mg Test with 600mg EQ but I don't know your experience level. My first Test/EQ cycle was only 200 and 400 and I saw solid gains.
3 weeks also isn't long enough for Tbol, I'd go 6. I don't really even start noticing it until week 3-4, then I usually see solid strength gains from weeks 4-6.
Again, I'd suggest not using steroids at your age. Your Test levels should be through the roof naturally and better nutrition with a lower bf would probably raise it more. Maybe throw in a SARMs stack if anything. Trust me dude, keep using steroids this early in life and you'll regret it. If you're not a pro bodybuilder making a living off of it, it's not worth it.
