So, I do a little work with Matt and love his products, etc. so I am heavily biased.
To me, BMP over Follidrone no questions. I am biased, and I would take BMP over any "Natty Anabolic" so it isn't a knock on Follidrone. I've used both. I have purchased, literally, dozens of bottles/pouches of BMP from Matt. I purchased one 2-bottle run of Follidrone.
Exotherm vs. DCP - tougher comparison. They are both geared differently and while I haven't used Exo in a long time, I ran 3-4 bottles of that and it was enjoyable. Being more of an AI angle vs. DCP being more PPAR and energy burning....they could both be complimentary.
If you are looking for straight fat-loss, Exo and DCP combined may be an interesting combo. If you could buy 3, throw in BMP.
If you can only buy two and want to lose fat but go for more of a recomp, BMP & DCP is the combo, IMO biased opinion.
I hate the idea of "recomp" though. You can lose fat much faster than you can build muscle...so limiting your fat loss to the rate at which you can build muscle seems highly foolish to me, to be honest. BMP does have a "recomp" angle...and I guess people see it as being great for this, but I see it as more of a muscle builder/strength product with some benefit in remaining lean/slight fat loss.
