In all honesty, it's not a fair comparison. You're literally comparing the reliable family sedan to the exotic sports car. Don't take this the wrong way, I love primo as much as the next guy; but it is really a mild and overrated compound in terms of results. In terms of side effects, well than obviously primo is the superior. Studies show that primo actually boosts the immune system, and in opposition tren is extremely taxing on the body. However, side by side, a test and primo cycle vs. a test and tren cycle... the results would speak for themselves; as would the cost.
