My first cycle I ran Test E 500 mg a week for 12 weeks. My experience since then confirms what howwedo107 says, after week eight gains slow down drastically. That extra two weeks will give your body time to adapt to the new muscle so you can keep more after PCT.
I agree with everything he posted. I would run 500mg a Week as 250 a week is more of a TRT dose...but if hairloss is an issue then slow and steady might be the best approach.
Make sure you get clomid or nolva for PCT. You might also want to have an AI on hand in case you start to get heavy estrogen side effects like bloat or gyno (I like aromasin / extremestane and forma stanzol as they are suicide aromatise inhibitors and won't cause estrogen rebound when you come off them like arimidex can). Everybody's body is different and you have to listen to your body, know what you are doing, be scientific about this, and know how to treat yourself if you start getting sides.
Good choice starting with test for your first cycle bro. I am of the opinion that any cycle should only include ONE new drug at a time, so that if something goes wrong you know what is causing what and how to treat it. You will get AWESOME gains off of 500mg a week of test E or test cyp. If this cycle goes well for you then next time around you can add something else on top once you know how you respond to the test.
Also, you might want to get some test prop to use as a kicker for the first few weeks. Test cyp and test E take about 3-4 weeks to really start kicking in. That's when you will feel "on" cycle and start feeling like jesus haha. But if you run test prop every other day for the first three weeks then you'll get more time "on", as the prop will kick in right away. It's metabolized by your body fast so you have to go every other day with it. Every M/W/F would be fine too. In that case you can get one 10 ML vial, which will last you 3 weeks at 100 MG EOD.
I would run something like this for my first cycle:
Test Prop 100MG EOD Weeks 1-3
Test E / Test Cyp 250MG every 4 days Weeks 1-10
Week 12 run clomid 50/50/50/50 mg ED for four weeks.
If you really want to do this right and be responsible, have some nolva and some aromasin or forma stanzol (mr supps) on hand in case you start to get puffy nips or get really bloated. Me personally, so far I'm not prone to gyno at all, but I bloat like a mother****er without an AI which I ****ing HATE. Also, I am not genetically prone to male pattern baldness judging by my family history but I'll be damned if I didn't shed a bit while on cycle. I can't really tell a difference or tell if it was permanent but I did shed.
Oh and the reason for injecting the Test E / Test Cyp twice a week, even though you technically CAN do it once a week, is that it seems to keep your blood levels more stable. Less spikes in test and estrogen (test aromatises into estrogen) mean less sides. When I inject twice a week sides are better. Once a week and I get more bloat, start getting some bacne, etc.
Good luck bro. Be responsible and do this right, and you can break barriers that mere mortals don't even comprehend. Proper PCT and ancillaries and being responsible is just as important to making permanent gains as the amount of anabolics you inject. Slow and steady wins the race. Get stupid and you'll **** your **** up, not keep any gains, and won't want to touch roids again.
Go kill this **** bro. Welcome to the table.
