Been using MTS products for the last 3 years with great results. No pip problems whatsoever until recent order. Started a new bottle of Test 400 with extremely severe pip problems. The pain is absolutely unbearable after 3 separate injections for the past 3 weeks, with each injection in a different location. I'm still a loyal MTS fan and hope that this bottle is just an anomaly. I will probably throw this bottle away and try different bottle to confirm any problems. Anyone else have pip issues with recent orders?
