We're nearly the same! Lol I'm 16, 17 in a few months and yeah a guy.
I haven't started yet, still waiting on my HCG to come, but I've done a fair amount of research. What you need to buy is HCG + a mixing kit. It sounds to me like you could do with a 23 day plan, maybe, because men seem to lose quicker than women on this diet (or in general). You could lose about 20 pounds on a 23 day plan, maybe more or (not likely) less. With the 23 day plan, you only need 1 bottle of HCG. You can do a 40 day plan which uses 2 bottles of 5000 IU HCG, so more expensive, but you can lose around 35 pounds with that.
You start by doing 2 days of loading, where you eat a lot of high-fat foods to ensure that your body will have enough nutrients to survive the diet, and to prevent hunger. You also start using the HCG during these 2 days. After that, you start the 500 calorie a day meal plan. It sounds like nothing, but the HCG makes you not hungry. You may need to adjust your dosage if you're hungry, usually to a lower amount. 150 IU is the recommended starting dosage. This is when you lose the big pounds.
I haven't looked much into the phases after the first 2, so someone else will need to tell you about that.
I got all of my supplies for about $80 total, and that's with the 40 day plan. If you choose to do just the 23 day plan, it'll run you about $60. You can order your kit from here http://hcg-injections.us, but that doesn't include the HCG because it's illegal to sell within the US. You order the HCG (I'm linking you to Hucog HCG because that's the most common brand) from this website https://www.reliablerxpharmacy.com/H...0-1-18014.html. Buy 1 bottle if you're doing the 23 day plan, or 2 for the 40 day plan. It's shipping from India so it'll take a while to ship. You don't need a prescription. They only accept Visa for credit cards, but they accept eCheck and some other methods.
Also, check out some of the sticky threads in the Newcomer Info section, there's some very helpful info
