Ok. Before I get into this I want to be VERY clear. 25 is not far off, and you can still make great gains. Also, I'm absolutely going to get flamed for this.
First, if your doing it because your friend is doing it, that's just being an idiot. He may have done irreparable damage, he just won't know it for a year or two. When his penis stops working tell him we have a great HRT forum. Again, THIS IS A BAD IDEA!!!
First cycle, and maybe third, fourth, fifth, etc... until you stop getting good gains is test, then add another compound. I've played with some orals, hate them. I've always done test, sometimes with EQ solely for the increased appetite, which I get big time from it.
Make sure you research proper IM injections and sterile technique, don't f*** this part up!!!
Test only
weeks 1-10 Test E split twice a week. Thats 250mg monday, 250mg thursday. Hcg 250iu twice a week. if your balls are still shrinking you can up it to 500 x2/week
Adex .5mg EOD
take 2 weeks off to allow the test E to clear from your body
PCT
Clomiphene: 4 weeks @ 100mg ed first 2 weeks, 50mg ed last 2 weeks.
Tamoxifen : 4-6 weeks @ 20mg ed (40mg ed for first 2 weeks if you wish)
Get blood work before, and after.
One last note. You say your diet is perfect, please give a complete breakdown, what every meal is, macros, etc... Lets see if we can get you gains there instead of with AAS
