Unless you have had blood tests and the results say that you are low on your natural hormone production, I would advise against running any sort of steroid cycle. Yes, there are as stated by the posters here many products that could juice you up. The only problem, you are naturally juiced up already. If you need a boost, there are a lot of supplements designed to increase hormone production safely, and support what you already have. I don't need to go into brand names and stores, I am not an advertiser. I will tell you that at your age, you are just off the assembly line. You are at the peak of your game. My best advice in this would be to start with legal supplements, and if you do not get the results you want with those, then try the 'roids. I tried several Test boosters that were not on the legal market, and a couple other things years ago when I got out of the army. I didn't get anything all that much better than I did while stacking powerful LEGAL supplements, and considering the help I had in selecting the products (several trainers/manufacturers, they made the stuff and had very elaborate production facilities) I had a lot of educated help. It is up to you, but at your age you might get better results in the long term (both in side effects and in long term results) by going the legal route. Good luck either way, and look up the side effects of abusing the products you intend to use. Hair loss and small balls would be the least of your worries if you screw up your cycle and misuse the products. Hope you have the results you are looking for!
What are these products.??
We did a load of testing here in NZ last year on popular market test-boosters, most didn't work full stop, only one or two from memory improved baseline by negligible amounts..
