Confirming other reviews... order in bulk with no expectation of shipping so DONOT pay extra because you won't get your product on time. 3 to 6 days mean 3 to 6 weeks. I ordered ipam, on the 14.. order filled on 18th still hasnt arrived at usps. No reply to email and no one answers the phone

Sent a email 24 hours ago they never responded. Called today left a message still nothing . At this point im wondering if ill ever get my order and they are a scammers.

After many orders from this company, I will say, the product is good but the shipping is terrible. In the last 6 months, my express and priority orders are taking 6-10 days. I spoke with the post office and this is not a USPS problem, but a problem at Extreme Peptides.
