First Cycle!

Test Enan 375 mg/ weeks 1-14
Letro .25 mg/ ED

weeks 16-20 Clomid 100mg ED/ letro .25 mg

Age 23
Height 6 1
Weight 220 soaking wet
BF% 15-17

Couple Questions:

Will it make a difference to run a 14 week cycle rather than a 16 week cycle in terms of safety?

Would it be more intelligent to run the letro EOD because of the severe estrogen suppression?

Is there any difference in safety if I run Test E 500 mg instead of 375?

What should I use to combat the estrogen rebound after I discontinue letro? Is there really proof that there is an estrogen rebound?

Thanks in advance and cant wait to get constructive criticism!
