lol, NO..just the opposite...your body theoretically will sense an elevated level of hormones due to these products and thus could/will surpess your bodies natural production, and therefore cause shutdown and potentially slow down your recovery process or potentially even cause long term damage (highly unlikely with these products at least if used as directed. Now if you were dosing much higher or dosing more frequently or for a longer period of time than yeah the likelyhood of permantnt damage is significantly increased).
Bottom line is taking a 3rd dose (assuming you split them up every 5-6hrs) is only going to increase the likelyhood of supression and/or increase the level/duration that you'll need to recover from said supression (i.e longer wait for your next cycle).
So the question is WHY would you take on the added risk unless the gain was worth it which in your case espeically with an unproven product at a pretty low dose (2 pills) I just dont' see. The real question that you need answered is WHAT are you gaining form taking a 3rd dose INSTEAD of adding that into your other two doses and therefore INCREASING the levels of hormones in your body during the DAY while also hopefully letting your body natually produce during the night. This is the beauty of a short halflife product. If I had to choose though I'd either do 3-4 pills two times a day or accept the shutdown/supression and add in another 3rd dose at the same 3-4 pills.
If I had to choose between a 4 week cycle and 6 weeks though I'd go 3 pills x2 for 6weeks before I'd do 4 pills for 4 weeks if that makes any sense. I also wouldn't waste this product by running it alone but thats just me so by stacking other products you can effectively get an increased benfit from a lower dosage since its being stacked.....1+1=3, which is the only reason I'd be willing to go as low as 3 pills/dose
