My Current (& Limited) Deca Experience:
I'm about 12 weeks into 400mg of Deca (750Test/600Mast). First run. Significant shoulder and knee joint relief by week 3-4. I'm overhead DB pressing again
and my right knee always felt a little irritated for around 24hrs post leg day.... hasn't bothered me once while on Deca. Definitely notice a slight "depression cloud" hanging over my head though, but after recognizing it for what it was, it's completely tolerable for me. Gains have been consistent, but a bit watery. No negative libido effects. I'm enjoying it thus far.
Pushing dose up to 600 for the final quarter of the blast. Not sure if I will blast Nandrolone again, but I definitely think a small dose will be a staple in the future for how good my body feels on it.
