"Anything where the dose is released over a number of days like EQ, Deca, Enanthate, Cypionate is suited to the front-loading technique."
Check out some of the clinical papers on enanthate for example. While the parent drug is released over a number of days, the peak blood levels of test occur within 12 - 24 hrs following the dose. I'm not sure I buy the front load concept per se, I think what most are experiencing is a huge increase in blood concentrations of the AAS and probably an effect on secondary receptors beyond the AR and/or complete saturation and activation of the AR with an large initial dose.
I'll dig around for some citations.
