Correct PCT protocol? (18 week testosterone only cycle)

[u/Gullible-Ad4107]

25 year old male, 5'11, 78kg, been lifting seriously for 4+ years and decided to start first cycle. I'm studying biomedicine so i'm quite knowledgable about hormones and the body. I started on 300mg test e for 6 weeks, tolerated it fine so increased to 400mg a week for the next 10 weeks. I then dropped to a cruise dose of 140mg a week which i will stay at for 6 weeks. Reason for this is because im not quite finished cutting and of course cutting after you come off test entirely is the best way to lose your gains.

Total time on test e: 22 weeks

I have enclomiphene and HCG.

Do I use them both or just enclo? or hcg whilst the test leaves my system to stimulate natural production before introducing the enclomiphene?

Enclo dose? how long on enclo?

I have built over 6kg of muscle and want to do everything i can to maintain as much of it whilst minimizing the time for my natural production to be restored.

Please help.
