TB500 - Why the Massive Variation in Price?

[edjohn88]

I am ordering some TB500 from Liska and the price is pretty reasonable at $25 but i see it sold for as much as 3-4 times that on sites like Peptide Sciences. Even between peptide marts the price point is all over the place with this one peptide in particular.

Why would this be?

To get it out of the way for those unaware, it's important to distinguish between TB-4 and TB-500, I explained it here: MESO-Rx Sponsor - Cat Café EU & US domestic

Here's the prices for raws from a high quality source to illustrate the difference in pricing between the two. Since the price per gram drops further when purchasing bigger quantities, and lower quality sources are cheaper to begin with, you can assume no vendor pays more than that for their product and make approximate calculations on profit margins for TB500 (almost always TB4).


I couldn't find any verifiable third party labtests on peptidescience's website so further comment is out of my comfort zone.

QSC is selling the frag 17-23 or thymosin beta-4 as TB-500?

Check their Janoshik labtest, TB-500 looks like:

I must be dense… are you saying the cat stuff is the more potent or its the full sequence and thus cheaper?
