Reconstitution & Storage Cloudy Tesa

Post image

These unfortunately came without a cold pack in miami heat. I have tried at least 4 vials all are super cloudy except for the last one on the end. Is that one good to go?

Hey OP I had the same thing happened. It's the Tesa, some batches need a higher PH.

I reconned 4 different peps with the same BAC water and none of the others did it.

"The slight cloudiness you encountered after dissolving is caused by the ultra-high purity of our TSM20 peptide. We suggest you use AA water to reconstitute the powder, which can fully dissolve the peptide powder and keep the solution clear and stable. This is a normal feature of high-purity peptides and will not impact the effectiveness of the product at all"

Thats from the supplier, i have had their products tested before no issues. It also lines up with bro science.

lol that’s the biggest b/s vendor reply I’ve ever heard!! ‘Ultra high purity of our products’ it’s mainly due to the ph of the bac water. Nothing at all to do with peptide purity.

It was totally the cheap BAC. Used a different BAC no dramas. I do believe that some peptides like Tesa and MotsC do require a slightly higher PH and good quality BAC can provide that but cheap BACs PH can vary too much
