Thought I would chime in here with my experience.....
I also experienced problems with SRC in regards to communication AT FIRST and gave them a good week or so to get back at me. Never heard back from them and also left them a voicemail, BUT due to the outstanding reviews I read, I decided to go ahead, trust in the users here, and make my purchase.
Once the purchase was made, I actually received a call back (they left me a voicemail) and they stated that if I had any questions or concerns, please call or email them. I was happy to receive the call, but I always check my SPAM mail and still never received responses from them on 2 of my email inquiries from the past. I did receive their "we received your inquiry" notifications, so I don't think that the problem lies within my or our emails, but rather within SRC.
If it wasn't for the GREAT reviews here, I would have most definitely passed on their peptides for this reason.
With all that being said, my order was shipped out the very next day and I received everything today. My wait time was around 5 days and that was just because USPS is slow!
I am looking forward to starting my 1st peptide cycle and if the potency is as good as many people state on here....i will be ordering from them again!! I state the problems above, so that SRC may be aware that there are numerous people out there trying to reach them and hopefully they can fix the "customer service chink" within their company chain of business.
