Is the Ostarine a stand alone? I understand it's cheaper to do so. But there are products that have key ingredients to help combat sides, increase mood and productivity. I only take these for that fact. During cycle I feel more energized. As far as appetite, it's not likely that two days in, you are predisposed to an increase in hunger form Osta alone. I'm assuming you have begun cutting, changing your diet and routine. This on top of your cycle is going to naturally increase your hunger until you adapt from what you previous diet and intake was like.
As far as a Test booster homie, this is the best advice I can give you. I have ran Osta both stand alone and with a product such as Ostashred. If you want to avoid the ugly sides of test decline, certain predicts have libido and mood enhancers to help you on cycle.
I DO NOT recommend taking DAA and or a test booster while on cycle. If your only on day 2. I would stop now. Pending the length of your cycle and especially if you are prone to low test, you are about to paint yourself into a corner. Towards the end of your cycle you will be at the peak of decline. If you run a test booster the entire time, what is going to bring you back to equilibrium at the end? I truly understand the mind set of keeping levels stable during cycle. But that will only work for so long, and will not be nearly as effective.
My cycle 8 weeks. My first two cycles I began a solid test booster at week 6 to negate any sides. This way by the completion of my cycle, I was ready to roll for a nice test boosting cycle, not just leveling off.
I fear you may pay in the end for little benefit now...
Even with low test, you need to embrace the cycle. Choose a product or add in supplements to negate sides. Even if test dips at the end, you will reap rewards from the boos thereafter.
I'm 36 and am at the point that I don't start a booster until the day my cycle is over. But for you, I highly recommend starting towards the end. I will look for your log. I have ran many successful cycles, and will be more than willing to help in anyway. Best of luck...
