NO , its due to your nuts not needing to produce testosterone due to it being injected in higher amounts that what the body normaly sees , so the breain sees the imbalance and tells the nuts to stop , the lack of use is called atrophy.
I use HCG during my cycle to keep them full and where they need to be , some guys use clomid during also with good results.
generaly guys will use clomid starting when the drug use stops and the expected time for it to clear the system.
From what I've seen and heard guys do they start 12-14 days after last test E injection , clomid at 200mg/ed for 2 days , then 100mg/ed for 3 days then , 50mg/ed for 10 days
Not 100% sure this is the best way but its how alot of guys do it
