well Im pretty knowledgeable about creatine. I'm guessing you just got some cheap creatine monohydrate from gnc....that's fine...mix 5g after your workout each day. No need to load, it's a waste, you balance out anyways in the end. To do list for starting creatine
1. Stay consistent with lifting....don't skip like 3/4 days, even 2 days in a row...creatine will work if you put in the time
2. Drink water, drink more water, and even drink more water.
3. In the end to get bigger you need to raise your calorie count...eat clean foods if you want to gain good weight
4. Creatine will make you gain weight in your lifts and in muscle size...but if your just starting to lift I recommend you lift for at least a week or 2 or more without creatine...let your body gain without anything. Beginners lift gains usually are huge-you should figure out where your at first before creatine
Thus you can see the effects of creatine and let your body get used to lifting weights CONSISTENTLY first.
In the end creatine is a good product for people who are serious about lifting. Not like body builder serious, but serious meaning your going to lift weights at least 3 times a week-preferable 4-6. Also, you need to take creatine even on days you don't lift weights, it is a product that needs to be consistently taken. Taking a few days off of it will make it worthless. GL, it's not that big of deal, creatine is taken by pretty much every athlete just know if you want to see the effects of it your going to have to lift, eat, drink water. Thats all hope it helps
