After trying, what seems like hundreds of different products, Vintage Build is a supplement that actually works. At 50 years old and a competitive bodybuilder, recovery from one workout to the next is essential. Vintage Build has given me that recovery that I've been looking for and after only three weeks of use, I've also noticed a substantial increase in strength. Old School knows the importance of the ingredients in Vintage Build and has made a product with just those ingredients. Thanks for a great product!!
