WTF?? This is a serious condition. Stay clear of ALL gear until you KNOW FROM MORE THAN ONE DOCTOR what the cause is, for CERTAIN. Nandrolone can exacerbate the condition -- this is well known. Two of the most overlooked issues in AAS users -- prostrate and pancreas. The fact is, on this one your doctor is probably correct about a correlation between your gear usage and the condition. Don't look to people on the board to convince you to do something stupid.

Remember, nandrolone actually increases intramuscular fat. Fat accumulation of any kind impacts insulin use in the body, and the pancreas generates insulin. That's just the the tip of the logic iceberg. You have to factor in the redistribution of water as well, and then the altered use of carbs, all topped off by the elevated triglycerides. These ALL impact the pancreas. It's the gear, my friend. Lay off until the condition vanishes, and if you do decide to go back on, do so under a doctor's supervision, and I recommend avoiding Deca like the plague.
