Welcome aboard bro. The earlier question about your goals was an important one. If you just want to increase your bench to 300, then getting on gear isn’t necessarily needed as you can switch up your training and/or find you a strength/conditioning coach.
If you are wanting to put on some size and develop your physique, then obviously gear would be more appropriate for these goals.
How much you bench has no relevance to how you look and I am sure most can agree that if you are walking down the sidewalk looking like a spartan that nobody really cares what you bench unless it is a fat guy wanting to brag he can bench more than you.
As far as what gear to cycle, do your research and gain the knowledge first. Don’t jump off the high dive with 3 different things when you don’t know how you will respond to test only. Also, make sure you health is in check and that starting gear isn’t going to put you at risk for anything else or complicate current health issues.
But if you choose to pursue gear after everybody’s advice, I would say start off with a simple 10 week run of Test E or C of 500mg per week to see how you respond and learn what to expect from it. Then on your next cycle, you know what to expect from Test and you can add something else with it such as Dbol or Anavar and go from there.
One last point, diet is key. Most people think their diet is on point but it usually isn’t. When you think you are eating enough, DOUBLE IT!
Crawl before you walk brother and don’t hesitate to ask questions.
Good luck
