Sigh.... where to start. You have ONE positive indicator already. Short fuse. Easily angered.
Take a breath dude. Listen up, would ya?
Let's for a moment assume that you are a healthy young male. Your natural test levels are decent to high. The instant (oversimplification ) you stuck that 1st 750 in your body, your natural test production STOPPED! So,while you build this artificial test level up, your natural test level crashes. That takes a little while to overcome.
Next, if you started with a whole 750, and if you are accurately calculating, and then went straight to a 250 3 times a week, and if you are shooting only enanthate, it will take 7-8 weeks for your test levels to peak. I just spent 5 minutes on roid calc punching all YOUR numbers. I'll post a pic of the graph myself if I have to. But you should know how to do this stuff yourself. It's part of being a responsible AAS user.
You should note some effects and the typical 'kick' that everyone comments on (read a few logs, would ya?) At week 6-ish.
What will you notice?
Body changes? No effing way. That takes months and months.
Will your weight change? Depends on your calories! Has nothing to do with test levels. You don't eat, you don't gain.
Strength gains? Yes, it won't be huge but if you were truly plateau then progress begins again.
Acne? For some yes
Oily skin? Yes
Could your gear be bunk? Maybe. Could it be under-dosed? Possibly. Could it be you don't know how to read a syringe or how many Mls x test concentration = mgs of test? What do I look like, your math teacher?
Can a bunch of strangers on a forum tell you if it's gtg? Eff no!!!
