Anything Wrong with My Cycle?

hello guys.

I ran my first ever cycle :
6 weeks of:

3 x 250mg test enanthate /week
50 mg oral winstrol ED

i faced severe testicular atrophy towards the end of the cycle.

MY PCT:
i started nolvadex 20mg ED for 2 weeks after 10DAYS (is it too early?, if yes what will it cause?) on week 2 i introduced clomid at 100 mg ED

i AM still facing atrophy on day 10 of my PCT, is it normal? will they grow back? or something like HCG must have been used?

Thanks
