Haha! Yeah, susp is pretty hardcore. Instead of the test being nice and smooth dissolved in oil, it's little undissolved crystals mixed with water. It's like injecting shards of broken glass into your muscles. Hurts like @#*& about 12-24 hours after the injection as all those little sharp edges rub against the insides of your muscles. While on susp, you can basically forget about doing legs because they will be too sore. Your quads will be in constant pain from multiple recovering injection sites, making it hard to walk, climb stairs, get into and out of your car, etc.
