I have heard that power feeding can cut down on your snake's lifespan because it is stressing the organs and body to grow at a quick pase. I would not call every five days power feeding, but once they are adults I would stick to every week. Once a week but with larger prey items or two prey items of equal size. I have been doubling up on feeding for a proven breeder female that has been fasting and is on the line of 1600-1700 that I want to get up to 1800 and breed her a bit late this year. I acquired by female pin four months ago at weight 97g and now she is 247, for comparison.

I would say go for it till they hit the mark you want them at, then slow it down in baby steps
