Tesamorelin testing shows 70% purity and 50% fills

[Scottjbco]

Finnrick has started posting results of Chinese suppliers. Under SSA, I noticed they have 4 recent tests for Tesamorelin.
1 test was decent
2 tests were 70-75% purity and 60% of the volume
1 test had high purity and was 10mg of the listed 20mg.
Essentially 75% of the tests are and they used 2 different labs so it’s hard to argue.

That's fairly worrisome.

I just checked out their website. After checking the testing results for Reta I went and found ZLZ Peptides. I’m going to give that source a test run.

Exactly. I’m going to send one of my Tesa’s in. I don’t mind if it’s off a bit but that’s terrible.

Guess im kinda glad I didnt order from SSA

How reliable is this website?
I did not know SSA even had 20mg Tesa.
Either way, will buy and send it in for testing next month..

Very few 3rd party testing for this on the forum..

Clearly some kind of error. SSA never sold 20mg Tesa. AFAIK no one ever has.

I'm assuming that's the 10mg, in that case the results are pretty good.

I like the idea on paper, but I've got a bad gut feeling about Finnrick. Especially since OP set up a brand new account to post about them.

There is at least one. Uther Pharmaceuticals. I have a kit of their Tesa 20mg in my freezer.

Anyone know how Finnrick makes money?

besides obvious speculation like being paid by sources, possibly sketchy and biased (time will tell if their tests match other testing services of same product, same batch etc)

They can't be doing this for free

 

[Scottjbco]

Yes. My account is new because I’m new to the peptide space. Finnrick is using other labs for the testing so it’s not their lab doing the actual testing.

As far as Finnrick’s motivation? The peptide guy on TikTok did a long interview with the Finnrick CEO. Judge it as you like.

The latest Tesamorelin Janoshik test I can find is 14 months old and my shipment was manufactured in June 2025.

Tesamorelin is really the one peptide that would benefit from single dose vials. It's very unstable. It is offered in 2mg vials, but the premium per dose vs larger vials is often very high.

Looks like SSA just added Tesa 20mg to their pricelist.
Can't lose out i guess lol

until I see another (hopefully trusted) party replicate those results via Jano, I'm taking Finnrick results with a grain of salt

Honestly in the peptides only market Uther is their closest competitors. I only buy from those two now.

Glad to see lower per dose pricing, but I'd rather pay more for smaller dose units.

It took Tesamorelin's developer 20 years to develop a stable enough formulation for a vial that lasts a week. It was delayed a year because the FDA wasn't convinced. They finally got approval and just released it.

The three previous formulations up to now have all been one dose, reconstitute and use immediately because of rapid aggregation.

Of course the manufacturer is gonna tell you this. According to the included paperwork, we're supposed to discard unused pharma Test Cyp and use a fresh vial every time too.
I'd like to see some jano data on reconstituted Tesa at 2nd day, 7days, and 28 days. They said this about MOTS-C too, and he proved that was BS.

I did not know this, Tesa aggregates rapidly, so was study done as in 7 days vs daily?

The price hasn't changed. The only difference is the new formulation is delivered in a single vial for 7 doses instead of 7 individual vials.

The tinfoil hat wearers are the ones who believe aggregation is a myth, perpetuated by a conspiracy of thousands of scientists, pharma, and the FDA and the Chinese UGL peptide makers are the real experts.
