You dont need a contact in Laredo, people will pull you off the street to sell gear to you. Although, most of it is more expensive than what you can get it domestically. It is all out of one warehouse and supposedly controlled by the Mex mafia. All prices are fixed at almost triple what you can get stuff in TJ for the only barganing is on the dealers profit.
Not to mention that if you look like you have ever touched a weight you will be pulled at the border and questioned.
Great prices on Clomid, novla, T3 and Clen though right out of the corner pharmacy.
