First of all, i started with the cutting andro kit and had a 6lb increase and the best definition i had in a year. It worked great, but i was a fan of LG SCIENCES now and i wanted to see what else i could do. I cycled off for 8 weeks and started this Battle Hardener kit. The 17 Andro works great, but i am really impressed with the P-Bold. I have upped my calorie intake on this kit to 3600 calories from my maintaining intake of a strict 2800. And i went heavy in the gym. This kit is really a bulking kit with the 17andro to keep you from gaining unwanted fat. It works and my abs that are finally showing are proof. I will be using this kit again in the future, but with the advice of lg reps, i will be extending the cycle by adding in an extra bottle of P-Bold to get even better results. Highly recommended!
