No need to take post cycle therapy (pct) for this. Yes ive tried and loved it. I know that sounds funny coming from a guy that uses prohormones but oh well. Prime does work for strength, anabolic pump does work to put food in your muscles (as glycogen ) instead of fat, and Powerfull makes you sleep and rest extremely well and recovery is the big difference here. Ive run about 4 Asteroid Stacks and saw results and felt its effects everytime. The only draw back is price.
