Payment Gateway for a Weight Loss Supplement?

After FDA issued warning against a particular weight loss supplement, most of the US processors are out of bounds. Most of the leading offshore processors are also out of bounds. Though we have extremely low chargeback rate, finding it difficult to sign a processor.

Any recommendations for an offshore (preferably European) payment processor with reasonable cost? Thank you!

The best way is to find a ISO that is registered with off-shore banks, You wont be able to simply contact the bank itself, too many different people in each department.

You can simply google ISOs associated with off-shore banks, but be careful who you work with as many of these places are "shady".
