I use the following drugs for post cycle therapy:
Crucial:
Clen
Clomid
Liquidex
Optional but very helpful:
HCG
Anavar
The most important thing is to end with a fast acting drug, my favorite being prop or anavar.
For example:
W1-8 Test Cyp
W1-10 Eq
W9-12 Test prop
W11-14 Anavar...low dose 15-20mg
You want to make sure all the long acting esters are out of your system by the time you do clomid.
Clen is crucial because it keeps your intensity in the gym...after 12 weeks of lifting you tend to get lethargic in the gym so clen is the way to go.
The trick to feeling good on clen is to start very low. 20-40mcg the first day and work your way up to 80-100mcg Slowly by going by how you feel. Don't rush into it or you will feel miserable. Clen also gives you a very slight rise in testosterone.
Liquidex is one of my favorite drugs and it's crucial in helping you keep your gains post cycle, and it also helps with acne from clomid.
HCG, I've never really liked. What can I tell you I've never really used it or needed to.
