Some additional thoughts on this whole Forerunner thing while I'm thinking about it...
Everyone's quick to point out the lower doses of the actives, but nearly all feedback on the Forerunner products is good. I have a theory about that, which runs parallel with a theory about testosterone.
Moderate doses of testosterone seem to be more effective than mega doses. I'm thinking that the moderate dose method of a testosterone precursor like 4-DHEA may hold true to that principle as welll, provided the delivery system is good.
Whilst you do not have the grapefruit to enhance absorption of the Forerunner products, the fatty acids in the carrier are very similar to the AndroSeries.
And yes, you could conceivably stack the Alpha Bulk (4-DHEA) with Alpha Mass (1-DHEA). However, almost all reports I've read indicate that the 4-DHEA by itself is not enough to mitigate the lethargy and loss of libido associated with the 1-DHEA.
Primordial also ran into this issue with the first version of AndroMass.
My suggestion would be to run a high dose of Forerunner's 5-Alpha Test, a healthy dose of Alpha Bulk and a lower dose of Alpha Mass. The synergistic effects of the two DHEAs would provide good clean gains and the synergy between the 4-DHEA and the DHT from the epiandrosterone in the 5-Alpha Test would help to eradicate the lethargy.
Dermacrine, obviously, would be a great choice, but it's no longer available.
