I decided to use Deca for the joint/pain relief and figured I’d use 200mg to get anabolic benefits in addition to that. Been on it for 15 weeks now. It has completely eliminated most of my joint/pain issues.
I can’t say I have had any negatives or side effects on 200mg. I probably wouldn’t be comfortable going higher for the possible cardiac risks you mentioned. The harmful heart studies were on rats that used doses around 1g per week what the human equivalent would be.
We know 200mg is safe for at least four weeks. Too bad this study didn’t go longer
Four weeks of treatment with testosterone or nandrolone had no beneficial or adverse effects compared with placebo on cardiac function in healthy young men.

Not that it is necessary in any way, but I am dosing it daily btw with my testosterone, so I am using 30mg per day to get to 210mg per week.
