first of all run test of some kind and chose either primo or deca - they are close to being the same so running them both together is a waste of time IMO
also shoot twice a week to keep blood levels more constant - I agree that cycle you have is bogus and not very well thought out
here is a little primo info from Big Cat;
Because it is a widely available steroid its often used as a replacement for nandrolone or boldenone to those who have no access to Deca-Durabolin or Laurabolin or Equipoise. When stacked with a heavy mass steroid like testosterone and/or methandrostenolone it can deliver almost similar gains. Those seeking to cut will most likely be very pleased stacking it with drostanolone, stanozolol or trenbolone. Women and beginners also stack methenolone WITH nandrolone because this gives a mildly anabolic stack that is generally regarded as one of the safer stacks around in an androgenic perspective. But alas, with the nandrolone, also a very suppressive stack.
see where it says when used with nandrolone it is very supressive? not what I would want to use together in a cycle
