i am so confident in the GP brand that i bought a bunch of the product that i will stash away for a couple years. They are excellent with shipping and know how to get it to me safely. i am loving their products. communication was smooth no worries ordering a bunch. packaging was solid tight with no problems. i ordered lots of test, winny, dbol, tbol, masteron, and ancillaries. results are impressive been using them for 12 weeks. Great results.
