solid start bro, 300mg is a clean first run. pin twice a week and only touch ai if you really need it. around week 4 you’ll start feeling the test kick in. stay consistent with food and rest and you’ll grow steady.

Solid setup, bro you’re starting smart and not overdoing it. 300mg/week is perfect for a first run, you’ll see good gains without wrecking your hormones. I’d say pin twice a week to keep levels steady, and don’t touch the AI unless you actually feel symptoms. You’re on the right track.

whats up bro, solid plan for your first test e cycle, looks like a smart start for lean mass and strength. I’m new to this too, been training a few years like you, and I’d suggest pinning twice a week (e.g., 150mg mon/th) to keep levels stable and watch for early sides, and use arimidex only if you notice bloat.maybe check in weekly to adjust cals if needed, best of luck bro!

Hey man,
Solid plan for a first cycle. It's smart to start conservative, and the fact you've built a base and are thinking about this methodically puts you way ahead of the game.

300mg/week of Test E is a perfect starting dose. You'll make fantastic gains on that, and it allows you to see how your body reacts without throwing the kitchen sink at it. A lot of guys make the mistake of going too high too fast. Split that into two pins, 150mg every 3.5 days (like Monday morning/Thursday evening). This will help keep your blood levels stable, which can minimize mood swings and estrogen-related sides.

Having Arimidex on hand is the right move. Do not take it unless you need it. The goal is to use the minimum effective dose of Test and manage estrogen with the AI only if symptoms appear.
Early signs of high E2 (Estrogen) to watch for: Water retention (puffy face, bloating), sensitive or puffy nipples, mood swings, or getting unusually emotional. If you notice any of these, that's your cue to consider the Arimidex. A good starting protocol is 0.5mg, and see how you feel after a few days. Don't crash your E2—low estrogen feels awful (dry joints, low mood, no energy).
You didn't mention it, but a proper PCT (Post Cycle Therapy) is non-negotiable. Have your Clomid or Nolvadex ready before you start. Get bloodwork done now (pre-cycle) so you have a baseline, and then again around week 6-8 to check your Test and Estradiol levels. This takes the guesswork out of everything.

Your diet and training look good. At 3000 calories, just be prepared to adjust. You might find you need to nudge that up a bit as the cycle progresses and your metabolism kicks up. Listen to your body—you're about to recover much faster, so that 6-day split will likely feel great.

You've got a great attitude and a solid plan. Stick to the basics, focus on your diet and training, and manage sides as they pop up. You're going to have a great first cycle.

Good luck.
