Okay, first of all, the guys on this post are trying to tell you the most important lesson you can learn. Yes, the books cost money, but if you want to see serious medical research from the Mayo Clinic, you would be amazed at how cheep these books you've been sent to really are for their value.
Check out Anabolics 2005-8, written by williamllewellyn. Newest year is the best, but I really liked the medical side of this book.
As for why, I'll be honest with you. The stuff you are thinking of using can be an amazing step towards better health and self confidence, however, if you don't respect the drugs enough to do about a good year of research, they can cripple you. Torn pec(not a pretty sight), blown HPTA-axis(This does recover in time, but you don't want to wait), loss of sexual interest, death...etc. AAS are some of the most powerful drugs on the planet and if used correctly can really help, but first ask yourself:
1. Am I the kind of guy who loses his temper(look at your post about the book and your idiot comment) Not saying that you don't have a right to defend yourself, but if you're this jumpy off AAS, you're going to fly off the handlebars when on them.
2. Can I handle getting a huge burst and watch most of it fade away, waiting long enough to ensure that your next cycle will continue to aid you.
3. Can you start slow, with just one, say just deca at 200mg/week for only 8 weeks. Remember, your receptors will build up a tollerance every cycle. Can you be happy with smaller, but more stable gains.
4. Do you understand the risks you're taking, both legally and bodily to the point that you even know how to have the stuff addressed to you? This isn't a joke anymore, especially with what's going on at the current moment.
5. Are you willing to accept that you really are new to this and take the advice from some great people here?
6. Do you even know why Anadrol 50 might be hard on your body?
If you can answer all those questions with an honest mind and heart, you are ready. Also, please don't take any AAS until after age 26. Your prostate begins a second growth phase at age 25, so if you're younger than 26, you should continue to push your body. It paid off for me and my left ventricle is still under 13mm in diameter(you should know why that is important).
Be patient, trust me. Reading as must as you can, with the internet at your fingertips, just type the drugs into google, visit medical sites, check out this site for questions like yours. No one here is a bad guy, but this question is posted nearly once a month, so check out other posts and when the time comes that you're completely prepared, then have a real cycle to post for suggestions.
Hope that helps and best wishes. Be safe, my friend, and research. It's worth it.
