hinestiy man, I had tren e in my first cycle, but it was stacked with test. Looking back I probably wasn't ready for tren, it's by no means a "mild" compound, it had some significant sides. You would be better off saving your money, and starting with test c or e.
Also, you never mentioned your age, training experience, goals, or diet. You really need to do some research on this stuff before you make the commitment of injecting an oil into your body. If you're looking to just add a few quality pounds, just eat more quality food. My advice, take it as you will, revisit your diet and training see if you can't make some minor adjustments there before you look to AAS.
