You cannot base your gear on the color of oil. Like Dawg said there are many different oils. Sounds like it working just fine if you gained 14 lbs and nip soreness. Here's what people don't understand, you don't automatically feel different. Some people get a good increase in sex drive, some don't. Sometimes it's different with different esters, not sure why, or different brands. Some times test can increase appetite, for some it won't. I remember everyone use to recommend 8 week cycles for me on test E but it took that long to start getting really good gains, don't get me wrong I gained before then, but at 8 weeks I was really strong and gaining like crazy.
Give it time to work. You are way to nervous about there being a problem when you have had results. Soon you should start getting stronger and recovering faster feeling like you could spend more time in the gym. I have to force myself out because I feel like I could go for hours somedays others I go so heavy I'm burned out in 30 minutes. Just give it time to work and stop listening to your friend because if he thinks he can tell by the oil he's crazy.
