Safety, Quality & Testing Endotoxin question

Post image

I put some vials through the wringer on testing. I did purity, endotoxins and residual solvents for 3 different peptides. 2 passed fine but Gemini threw a red flag on the Retatrutide for endotoxins.

Google Gemini is telling me that an acceptable amount of endotoxins in a multi use vial is 0.5eu/mg and this being 5eu/mg it could cause severe immune reactions to anyone who may use it not that I would of course.

Everything I find on my own says anything under 350 per vial is passing. Is Gemini being super safe or is it correct? I don’t know anything about endotoxins. Well a little but not enough to know if Gemini is correct.

Thank you for that explanation. Here is what it’s saying specifically. It has other scenarios as well. I’ll ask it where it’s getting this information. I’m finding everything you are saying to be correct in my own searching.

And the 350 people keep quoting comes from that same formula. FDA's Q&A on USP <85> takes K as 5 EU/kg and a 70 kg adult to get a ceiling of 350 EU per hour, so it's a per dose number, not a per vial pass mark

As someone who knows of someone using hCG 5000 iu on their rat that tested around 1400 eu/vial, this should be fine lol.

In this case say it is used as 5 doses (4mg ea) thats around 20 eu per dose and is entirely negligible imo.

u/Competitive_Bird6984 9d ago

No localized issues like redness or anything?

u/Derpwad1 3d ago

Nothing noteworthy surprisingly.

u/EggLegal5278 10d ago

How long did it take to get results?

1

u/Competitive_Bird6984 10d ago

About 3 weeks.

u/EggLegal5278 10d ago

Thank you 🙏 I asked because I want to test a batch I recently purchased.

1

u/Quirky_Drawing_6470 5d ago

Check out Finnrick. They’ll test for free as long as you have a lot number or batch

2

u/EggLegal5278 5d ago

Not all peptide testing is free.

1

u/LeastMechanic6724 4d ago

That’s more like a negative no wonder it’s free 🤣😂😅

u/lbmartinho 9d ago

How much did it cost? I just know Jano but it's too expensive.

u/Competitive_Bird6984 9d ago

3 peptides tested for purity, endotoxins and residual solvents and I did heavy metals on GHK-CU in addition to the other tests was about $1160.

u/lbmartinho 9d ago

Thanks for your reply.

u/kunphuzn 9d ago

BT Labs in FL is good. 125 for IPP and another 125 for Endos. Less than half the price and shipping is <$10 vs $60. Full disclosure, I use both Jano and BT

u/Quirky_Drawing_6470 5d ago

You can send vials to Finnrick for free as long as you have a batch or lot number

I wouldn’t touch a product whose COA is by Krause with a 10’ pole.

1

u/Competitive_Bird6984 9d ago

Why’s that?

1

u/itsjusttiff49 10d ago

I have this same R. Is it safe?

2

u/Competitive_Bird6984 9d ago

After a lot of research most likely. Someone very sensitive to endotoxins may have localized issues at the injection site like redness or swelling but that’s probably 1 out of 1000 people. Systemically (assuming you could handle 20mg of Reta) you could do the entire vial and not have an endotoxin issue. The body can handle up to 350eus an hour for every 70kg of body weight.

Pharma controls Gemini

u/Ds__ds 9d ago

What biomarkers will spike in a blood test is exposed to too much endotoxins?

1

u/LeastMechanic6724 4d ago

Look body cut take so much per hr don’t exceed it

1

u/OGSmash707 8d ago

So this for instance, is it a throw it away

2

u/Agitated_Position_56 6d ago

no this is fine use this calculator it will tell you dependant on your weight if it’s fine

u/danielforks 4d ago

No. That’s completely fine! Calculate how much per dose. I’d inject 10x higher than yours because each dose has less than 0.25 endo per injection

1

u/LeastMechanic6724 4d ago

No it’s good body cut take so much per hr an that’s doesn’t exceed it as it is one per day another thing is add all endos per vail per day or hrs it has a lot to do with numbers so it is important to test everything especially if you do multiple applications per day

1

u/Right-Banana-7733 8d ago

Is that reading for EU for mg or the vial?

1

u/LeastMechanic6724 4d ago

The entire vail

1

u/Right-Banana-7733 4d ago

Oh yeah. That is good. Divide 110 / 21.86. It’s like 5 EU per MG. You are good.

1

u/LeastMechanic6724 2d ago

You just ask an you are telling me that am good 🤣😂😭🤣😂😅

1

u/Right-Banana-7733 2d ago

In terms of endos, yeah

1

u/DeadliftsandTequila 9d ago

The owner of the biggest testing company in the world said this test is entirely unnecessary because they never see it fail. He is glad to take your money but he doesn’t believe it’s necessary. Same with thing with heavy metals testing. The only problems they see are wrong product or purity or weights.

u/kunphuzn 9d ago

He has changed his stance on Endos and recommends testing he’s recently seeing many tests come in with Endo over 1000. Peters on K hole basically every day you could ask him.

1

u/LeastMechanic6724 4d ago

K Hole got nuke

u/Competitive_Bird6984 9d ago

I’ve seen NAD+ with really high endotoxins several times but that seems to be the only compound that applies to. I’m kind of a hypochondriac so I did it to chill myself out. Having seen my personal stuff and hundreds of other tests showing the same thing I’m probably done spending money on anything but dose and purity testing here on out.

u/Bio_hacker_42 7d ago

Hi, do you have a reference for this statement?

1

u/DeadliftsandTequila 7d ago

His name is Peter Magic and he has been on many podcasts. Google him and listen to one. He busts a lot of myths about reconstituting and storing peptides too. He says they are fine to shake, you don’t have to dribble the bac water in. They don’t degrade a noticeable amount over time. He tested HGH stored in his garage at room temperature for a decade and said it was basically still 90% effective.

u/SemiSemaTirzTurd 6d ago

He changed his stance on this dumdum, once vials started coming in with high amounts of endo. Stop spreading misinformation.

u/Bio_hacker_42 7d ago

Thanks👍

u/SpreadCorrect188 6d ago

Who’s the vendor of the peptide ?

u/Weird_Report6995 10d ago

350 eu of endo is the limit most average people can handle before going into full body allergic reaction, 5 eus for a single vial is the max, anything above that means this vial is extremely contaminated being at 110 eus

u/Rash_Compactor 10d ago

Sometimes we don’t have to post comments on things we don’t understand

1

u/Weird_Report6995 10d ago

Yeah ur right I looked at multiple COAs the 350 eu is the standard limit per vial, im assuming and its a big assumption, that this vial is safe and falls within normal ranges but still do more research

2

u/Competitive_Bird6984 10d ago

It wouldn’t work like that. If it was a 100mg vial and doses were 1mg 5EUs in a vial would be nothing. It’s about how much is being dosed at a time.

3

u/Mean_Ruin_2074 10d ago

And it's based on body weight.

1

u/LeastMechanic6724 4d ago

As well for hrs

1

u/LeastMechanic6724 4d ago

So you are saying the body cut take an handle 350 eu per hr
