You want to do 300mg of prop ed? Thats 2100mgs a week. Do you mean 300 a week? Prop is also very different than sust. What is your cycle history and what are your goals and stats? Cant really give you any good advice without that
there's no way to answer which stack is better because what is good for one does not mean it is for the next... the best cycle is whats best FOR YOU...
I don't have any scientific evidence for this but I have always had the theory that you will get the fastest muscle growth by stacking together: 1. Testosterone or testosterone derivative 2. Nandrolone or nandrolone derivative 3. DHT or DHT derivative
I have seen fantastic results from using the aforementioned stack with clients.
For bulking a sample cycle might be testosterone, deca and primo
For cutting a sample cycle might be EQ, Tren and Winstrol
