I used Hospira. It's just strange that two of them were crystal clear and two weren't even though they were from the same batch and reconstituted exactly the same.

I purchased a LOT of peptides from EZ Peptides, including almost 30 vials of 10 mg Tesamorelin. Last week I was reconstituting a couple of vials, the same way as I always have, and one of them was noticeably cloudy. I decided to reconstitute two more (so I did a total of 4). The second two were perfectly clear, and after comparing all 4 of them, one was very cloudy, one is slightly cloudy and the last two I did were crystal clear. I wouldn't have noticed the one that was only subtly cloudy if I hadn't reconstituted those last two and compared. The two clear ones are on the left and it's easy to see the cloudy one second from the right. The one on the far right is the slightly cloudy one. I have never had this happen before and have reconstituted Reta, Tirz, SS-31, MT2, MT1, and over 20 vials of Tesa.

I'm not sure if there is any recourse with the supplier when this happens, but I wanted to get advice. Has this happened to any of you and how did you handle it? Should I just throw the two vials away and eat the loss? Or is it worth emailing EZ Peptides to ask if they'll replace them? Also, is the slightly cloudy one trash or would it be safe to use if filtered? I'm probably going to err on the side of caution and not use it, but just curious of any other opinions.

Great study, thank you for doing that and sharing the results!! One question...for the refrigerated temperature, did you mean 34 degrees, rather than 4 degrees, which is well below freezing?

@mtedeschi I saw it on Uther's price list

@brithus sounds like a great product, thanks for the link! I just ordered!

I bought two kits of R12. Super easy ordering system!

I was getting terrible welts from using GLOW, so I discontinued it and decided to try KLOW instead since it includes KPV which is an anti-inflammatory. I have been amazed at the difference. I now get zero stinging or welts. One thing to note is that I bought these from different vendors, so I can't be 100% sure that there weren't any other factors causing my reaction to the GLOW.

I've noticed that blends like KLOW often only show the mass of each peptide, and not the purity. Nexaph's testing group for KLOW specifically says "For this batch we will look for mass only and will not test for purity as it's not possible with peptide blends". However, I'm looking at another vendor's website (Orbitrex) and it shows a test report for KLOW that DOES include an "average purity" for the blend.

I'm strongly considering buying a kit from Nexaph since it's so much cheaper than single vials, but I'm not sure how comfortable I am without the purity testing. Anyone have thoughts on this? Another consideration would be to buy kits for each peptide separately and blend them myself, but what a pain.

Thanks. I looked again on Amazon but still could only find 30g or 32g luer-lock needles. The only 31g I could find were the needle/syringe combos. Strange. Oh well, I decided to buy the 32g 4mm.

@Randy I saw one of your YouTube videos where you were combining peptides from three different vials into one syringe. After you combined them into one syringe, you put a 31g 8mm needle on the syringe. I have looked all over Amazon and the internet and I cannot find 31g needles that aren't pen needles. I was able to find a couple of listings for 32g needles on Amazon but they were 4mm. Any suggestions?
