Outstanding TB-500
Thymosin Beta-4 fragment can be tricky to source at high purity. NexPep nails it. Our independent testing confirmed 99.2% purity which actually exceeds the COA. Very impressed with this compound.
fast delivery perfect product
got it in 2 days. dissolved instantly. tested clean. everything you want from a peptide purchase. will reorder
Using alongside BPC
We run both TB-500 and BPC-157 in our studies and source both from NexPep. The quality is consistent across both products which is important for our comparative work.
Clean compound
Crystal clear after reconstitution. No particulates. HPLC showed a single clean peak. This is properly manufactured thymosin beta-4 fragment and the difference between this and cheaper alternatives is measurable.
Wish it was 10mg
Great product but at 5mg per vial, we go through these fast. Would really love a 10mg option for less frequent ordering. The compound itself is fantastic quality. that's not the issue at all.
Reconstituted beautifully
The lyophilized cake was in perfect condition. firm, white, uniform. Dissolved in bac water in about 10 seconds with gentle swirling. No residue, no particles. Textbook reconstitution.
