Was going to leave a review on the main page, but in the drop down menu of peptides to choose from, Lipo-C and L-Carnitine are not listed. But I really like ordering from Penguin. They always seem to have great deals, and always sends a 10mL vial of BAC with every order. My only hang up is I think there should be somewhat of a discount on their L-Carnitine I ordered. It's listed as being 6000mg/10mL, or 600mg/mL, when in fact according to the testing, it's is actually 499.20mg/mL. But other than that they have have great products and I will continue to purchase from them.
