When you say naps are stronger,do you mean If i take 10 5mg it's mg to mg they are stonger.At $40 a 100 for Russ it would cost around 200 bucks to get 5000mg worth but the ip are $100 for 100 tabs at 5000mg so $ to $ the IP are a better deal..I have always taken Russ but are able to get IP and they seem like a better deal..........
