I agree with like a weed. Everyone says if you are on here and pay attention sources will fall in your lap. Maybe I'm obtuse but that defiantly hasn't been the case for me.
I have mixed feelings about eroids. Their forum moderators are atrocious. Most of them seem to have borderline retarded IQs AND they are geeked out on huge doses of drugs to the point their anger, aggression, and ability to think rationally are severely compromised. There have been many mods who ended up getting banned for playing games with sources. I don't think there is any way you can avoid this. One man will never make it is his full time job to moderate these sites, and there just isn't enough money to be made in it. You'll always have volunteer moderators.
I don't participate much on this forum, mostly because I am busy, and am active on other ones. I heard about that mod here who passed away however, and he sounded very straight up, so I'm going to try to stick around more often. Basically, this is my 2 cents
1) Street dealers often can be better, depending on where you are. Here in NYC, a bunch of Chinese in Queens are into this game, and they have fire product. If you're in a small town, you will probably be out of luck. It helps buying from someone who is real. Even most black market dealers are not total thieves, otherwise of course - they'd just be thieves. There is nothing wrong with going to guys in your gym who are clearly on gear. Look at their trap muscles, that's a sure sign of gear usage.
2) What people mean on boards is stick around, be active in the community, make friends. It's a time investment. Sure, don't take a PM suggestion from a total stranger. But, if you've been interacting with someone for a year or more, or whatever your persona threshold is, it's probably ok. If you're at a site like Elitefitness, which is RIFE with all sorts of corruption - this is not true. Those sites have long-term pro scammers who work for many outfits. But, on sites like this, it's pretty safe. Back to elitefitness, need to build muscle is a huge red flag. They are a truly evil company. If ANY forum allows promotion of them, be suspicious. If there are no obvious flames, do not trust anything that goes on there.
3) If you're going to use eroids, my advice would be to AVOID the top 10 sources. ALWAYS check to see if a source is discussed on another forum. If it isn't, do not use. There are 1 or 2 GREAT sources that are always in the top 25, but never the top 10. One of them I've used for years.
