I've been looking into a really good pre-workout stimulant and it sounds like JACK3D or a RPM/Drive stack is what I am looking for... Is there anyone who has used these products and if so what is your opinion on which is better? Also, I was wondering if there was any negeative CNS side effects after use... Any help would be great!
Whether you use Jack3d or RPM/Drive would depend primarily on your goals, and also whether or not you are using a separate creatine product.
If you ARE using a separate creatine product, then I would recommend wither NOT using jack3d, or using Jack3d and stopping use of that creatine product.
RPM/Drive stack is great if you are looking for leaning effects and improvements in performance.
You can also actually stack Jack3d, RPM, and Drive together.
You shouldn't get any CNS effects from any product. If you had these, it would be more due to your training and OVERtraining.
RPM is awesome as is. Jacked is good but I need to take like 3-4 scoops of it after the first coupe doses. Nutra has a good deal on black cats 19.99. Ill be trying RPM/Black cats real soon. Looks like it could be a killer preWO combo.
LOL. Be prepared. I'd recommend starting out with only 1 cap of BLACK CATS and HALVING your usual RPM dosage!
any tips on dosage, or when to cycle on or off?
On what?
Dosing/timing instructions for each product are on the product labels.
Re "cycling", any product that contains stimulants (i.e. Jack3d, RPM, etc.), it's recommended that one uses in cycles, so to allow their body a break from the stimulants, but it really depends on the individual as to how long they use each product for...RPM/Drive can be run up to 12 weeks before I would recommend taking a 2-4 week break.
