TOP NOTCH COMPANY. This is my first time ordering peptides . I'm a novice. But the gentleman who call me from Peptora regarding the shipping, was so kind to help me understand what to expect and how to better prepare. The vials arrived in no time, even though I'm on the opposite side of the country. Well packaged. I will not hesitate to recomand or reorder from them. My phone calls were answered in the most professional manner. I am a 56yo female.I ordered RT. Looking forward for more collaboration. THANK YOU.
