I would start the Test E on week one as it takes a few weeks to build up in your system. I would buy some AI I found some from research labs online for like 50 bucks. Take .5 of that EoD or 3 after you start feeling it build up. I don't know about the Hel I might drop that and save it for next cycle. Make sure you got all your PCT stuff before starting too. and me personally if im going to shut myself down at age 25 ( I wouldn't ) I would run some Hcg or whatever its called to keep your own test producing so you don't have no issues. your gonna regret it one day when your own body don't produce its own test and your shrinking up fast and having issues with soreness, tired, ect. you have to think long term sometimes because weather you realize it or not you will be old one day and be dealing with the decisions you made.
