In three or four weeks you can lay a good foundation. It's unlikely that, unless you have a very low percentage of body fat, you'll be able to see any muscular development in three weeks. Your poundages, however, should increase, which will demonstrate a strength gain. There's no trick to it. Train hard, plenty of rest and sleep, and eat properly.
Do the basic, multi-joint exercises, namely, squats, deadlifts, presses, rows, dips, and chins. Focus on overall growth. You can also use other multi-joint exercises such as farmer's walk or sled pulling, but generally avoid single-joint exercises. You must eat correctly. For example, you should be ingesting plenty of protein from natural sources and avoiding refined processed carbohydrates. Drink plenty of water. Avoid over-training and get plenty of rest. It's better to think of it as a lifestyle. For the free exercise and eating plans to get you started, see the page links, further down this page, listed under Related Questions.

If you gain muscle mass then it will stretch it. But if you gain a lot of muscle mass then it will stretch it and make it fade color. Depending on how much muscle mass you gain will depend on how much it stretches and fades. the tattoo should stretch to fit with your new size. however using steroids will cause the tattoo to stretch too far in one direction or another, thus permanently disfiguring it. whether it will fade i dont know. but the tattoo will resize with you skin (Assuming natural muscle growth).
