1) I find your stack is great!
2) If one cap of RPM and one cap of Drive work nicely for you, you do not need to increase dosages at all. Your bottles would last forever! Count yourself lucky! I did up to 9 Drive and 5 RPM briefly at some point in time.
3) Both RPM and Drive contain Naringin, a compound, known amongst others, for its ability to enhance the absorption, and consequently, half-life of several other compounds. This, and coupled with the fact that RPM, Drive, and Activate Xtreme, all contain Icariin, suggests you may even want to start your Activate Xtreme dosage low (2 caps per day) and ramp up slowly, if you see a need to. I say this because if the RPM and Drive dosage recommendations for your weight category are too much for you, then it is likely that the full dose of Activate Xtreme would also be too much for you. So, start Activate Xtreme low and ramp up, if necessary.
4) Icariin, a flavonoid cGMP-specific PDE-5 inhibitor, is generally well tolerated at recommended dosages. In extreme cases, consistent overdose may produce gastrointestinal problems such as nausea and vomiting. Furthermore, dryness of the mouth, tachyarrhythmia (irregular heart beat), fever, nosebleed, dizziness, problems with tendon reflexes, and low blood pressure (dilation of coronary vessels) may be noticeable. Long-term use may produce aggressiveness and irritability.
These are extreme side effects, and are not to be expected with normal icariin supplementation.
5) I would recommend that you do your planned stack for a maximum of eight weeks, pause for four weeks, and continue for another maximum of eight weeks, if you wish to re-run the stack.
Feel free to let us know, if we can be of further support. And all the best with your stack. You should see nice gains :thumbsup:
