You can run a couple of cycles and get back to normal with proper PCT after each cycle.
Test e 150mg twice a week Monday and Thursday for 12 weeks.
2nd cycle 250mg twice a week Monday and Thursday for 16 weeks.
Eat right and train hard with moderate cardio.
You will need to take a 12 week break between cycles. PCT will start 2 weeks after your last injection of each cycle. Clomid and nolvadex are the 2 PCT drugs you will need to get. You will also need to get anastrazole in case of high estrogen problems occur during cycle. There's a top rated source section here on this forum but I am not allowed to straight up give you sources names. You can get everything you need for your cycles.
This is the best advice you're gonna get anywhere! Just as long as you're patient, and stick to correct dosages. Actually staying at 300mg a week and not getting carried away, then doing your 4 week pct, then waiting 12 weeks before starting another cycle... you should have no reason to worry about messing yourself up. That only happens when new people take way to much, like 1,000mg a week. Or take several different things for the first time. They think I want to get jacked so I'll take 800mg of test, 600mg of deca, 600mg of tren and 50mg of dbol every day. Not only is that incredibly dumb for a first cycle its dangerous. Not to mention more doesn't always mean more! Meaning more gear doesn't mean more muscle!
Honestly you don't need to start to gear. Losing 20lbs is all diet and training. You can easily do that over the next 6 months with proper diet and training... or the next 3 months with 300mg of test helping you out!
But its not magic brother, it only helps as much as the work you put into it! If you don't train and diet, all the gear in the world won't help!
Also yes, oral only cycles are not the way to go! That's a fad becoming popular because of idiots on YouTube and tick tock. They have no idea what they are talking about, meanwhile promoting anavar like its the answer to all your dreams! Its not! A anavar only cycle will only hurt you.
As for the wonderful advice given above... I promise it doesn't get any better than that. I'm on a 300mg test e cycle, I love it! Absolutely love it.
I recommend you read and reread it until you completely understand what he said, if you have any questions please feel free to ask!
It can seem a little overwhelming at first. its not nearly as scary as it seems!
You need 2 vials of test. A bottle of Arimidex in case high est sides occur. that's something that you only take as needed!
Then you need your clomid or nolva. Some people do both, others choose only 1. That's your 4 week pct. Then you only need a box of 23g 1.5" syringes. When you break your list into the 4 main necessities, it gets easier.
1-main cycle (300mg of test)
2- Arimidex, for high estrogen sides if and when they occur
3- your syringes for twice weekly injections
4- Nolvadex and-or Clomid for your 4 week pct.
