I know everyone is different on how they react with drugs so I would start very low to see how it affects your body. I started out taking a quarter of a ml and now I take a half of a ml every 4 days. It's dosed at .50mg per ml.
There are some other good side effects that I've noticed as well.
#1 Popping various erections throughout the day for no reason at all (some might say this a bad side effect but I like to think its a bonus)
#2 After unloading during intercourse (fucking) it's rather easy to stay alert (sporting wood) only a few minutes after.
#3 Improved hand eye coordination. I operate heavy equipment (cranes, track-hoes, back-hoes, the wife, extenda boom fork trucks etc.) and I've noticed an improvement just in those actions of operations. In the gym I've noticed a marginal improvement over control of free weights.
#4 I sleep better throughout the night. Caber makes some people tired after taking it so I take it before bed.
The bad side effects
#1 The first two days I noticed my blood pressure had dropped. It was enough to wake me up after falling asleep!!! I also had shortness of breath The first two days.
If you take blood pressure medicine you definitely need to monitor your blood pressure if your still planning on taking it.
# 2 There's some information you need to research on your own about long term effects associated with higher doses that may have a negative impact on valvular heart disease. Some studies suggest that there are long term sides and some studies suggest that there isn't.
Anyways I wish you luck in your endeavors and as always have a great fucking day guys!!!!
