To be honest, I’m not a fan of pulsing. Your HPTA is going to be just as suppressed by dosing ED or E3D. I believe you should just cycle or not cycle, and if you’re going to cycle then drive it home with an effective enough dose to make it worth your time
If you do choose to pulse, then Sustain Alpha may limit some of the HPTA suppression, but I would personally just recommend it for PCT.
BTW, you are getting about 120mg of 99% pure resveratrol and 70mg of 99% pure 7,8 Benzoflavone with each 5 pump application of Sustain.
