There aren't any protein powders specifically designed or aimed at 14 year olds, but whey protein would be completely safe for 14 year olds, since its basically derived from cheese. Insure it is just whey protein your buying though as some powders may have things in that would be dangerous to 14 year olds (mainly testosterone boosters)

At 14 years of age, the best supplements your son could take are eating eggs, meat, and protein powders with whey, but start small and work his way up.

Too be honest, I wouldn't recommed it. If you are performing you weight training at a high intensity, your stomach might not like the eggs very much. On the other hand, you are on the right track because taking a protein supplement before lifting is a good idea. Try drinking a protein shake before you lift, or some other good source of protein right before. If you cant, or don't have time don't really worry about it. The most important thing to remember is DEFINITELY get your protein intake right after your workout. This is a major contributor to muscle gain. Your body needs all the protein it can get after a hard workout. Just remember, your body can only metabilize (or break down) about 40 g an hour so don't over do it or you will just be wasting it. For instance if you come home from your workout and drink a protein shake at 20g, eat a chicken breast at 20 grams and eat 2 hard boiled eggs and 14 grams, your body will only use about 40g of that in a hour and you will get rid of the other 14. Hope this helps!!

is it common for teen girls between the ages of 12 and 14 to get streachmarks in the thy area
Yes. You do not specify, however, the kind of work out, so it is difficult to be more specific. However, make sure that calories from proteins do not make up more than about one-third of your total calories. Normally a post-workout shake should have, in addition to protein, some high glycemic index carbs to help transport the protein into the muscle cells.
