Personally the blend will allow me to utilise the benefit of each compound without breaking the bank by buying them all individually. I know it's not ideal as most prefer to have all their gear ready however this will allow the purchase of one vial precycle and the other 3 weeks in. Although I'm sure the blends do attract some that perhaps don't understand the stack, for others it can provide an opportunity to cycle stacks they otherwise wouldn't have been able to financially.
