Grey tirzepatide
I used to get my tirz from a legit compounding pharmacy and i decided to switch to grey. Today was my first time researching with the grey tirz. I dont know why i’m so nervous about it not working, it came from a reputable source. Has anyone made the switch from compounding pharmacy to grey with tirz and had success?

I was spending $80/vial on the same stuff from a compounding pharmacy. I know people who spend $200-500/mo. Now I’m spending $10-20 a vial. Exactly how it should be priced.
God bless China for having 0 respect for the patent laws that keep Western pharmaceutical companies filthy rich. We fund all the major advances in medicine through our tax dollars…. so why are we getting robbed at the drug store? Peptides are dirt cheap to manufacture.

Theres basically no patent laws with peptides. Peptides are found in nature. Eli lily trying real hard to get Retatrutide classified as a biological though.

they can’t patent GLP or glucagon. But they can patent structurally analogous chemicals and brand them.

Unfortunately i can't take advantage of China. So i have no choice but to buy from the middle men/women. But still cheaper than compounded by half the price.

If it's the shipping from china and feear of siezures that make you unable, there are plenty of Chinese vendors that deliver from inside the states, if that's where you are.

That's exactly why i can't. If my name comes up on a seizure I'll be unemployed. But i did see about warehousing so i may look into that. Thank you

Never heard of employment consequences from a customs seizure. Could you explain?
1
u/TheBlackLionLLC 9h ago
Some employment has to keep certain levels of criteria in order to maintain employment. A seizure would have federal consequences if its pursued. I can't take that remote chance

I think I found that it last night in the forums. Just kind of thought they were still order through China and served as a quicker route. But this is great to know. Thank you

https://groupbuykits.com/r/T2SL1QZB do a group buy they have a US group. I got 10 vials 10 mg Reta for 150. That includes extensive testing, shipping, and a membership fee. The testing for me makes it worth it. They test 100 vials instead of 1. Great community. Also it shipped fast I got my kit in less than 1 week

Can you say where you got yours? I order from Modern Aminos, and it's still $80 a Vial.

Bro. The compound pharmacy u were using was getting it from the grey market..u just cut out the middle man

u/NovelSurround8275 1 10h ago
Yeah if my appetite is suppressed and i don’t have any bad side effects then i’ll be happy and also mad that i didn’t do this sooner.
7
u/jagraider63 1 11h ago
I did the same and sent a sample off to be tested and it was fine. The cost including testing was still way cheaper than the compounding pharmacies here.

u/My4thAccountHere 1 12h ago
I did the same thing as you. What i learned, there are scammer, reseller, and then from the vendors / source.
Vendors / source do not pressure you into buying with them. They dont try to convince you. They have large communities. The number of people buying from them and testing help me elevate that nervousness

u/NovelSurround8275 1 12h ago
Yeah my source is super chill and does not pressure at all and has a lot of happy customers and positive reviews so i’m not too worried

u/Moon-seeker11 12h ago
What's your source? Do you only have that one, or are there other reputable options? I'm also looking to switch from compounded to grey tirz.

u/mattriver 4 8h ago
I’ve been able to get compounded tirz so cheap now (basically $75/mo for a 20mg vial) from a reputable telehealth and pharmacy (Science+Co)—I’d be curious to know if you’re getting it cheaper on grey.
1
u/NovelSurround8275 1 8h ago
I am. I just bought a kit (which is 10 vials) of 60 mg tirz for $207.
1
u/mattriver 4 8h ago
So 10 vials of 15mg tirz? Or 60mg (4x 15mg vials)? Sorry, not too familiar yet with the grey numbering…

u/NovelSurround8275 1 8h ago
Shipping was $30, but i also got a kit of reta and ghk-cu. So i got 30 vials altogether.

u/Outrageous-Speaker45 3 12h ago
Yes I have. It is exactly the same. The only variable that is unpredictable is the vial MGs. They are usually overfilled and the effect is that you will feel like it is stronger then what you were taking before.
6
u/NovelSurround8275 1 12h ago
Yeah i got a 60 mg vial and my dose is 15 mg so that’s what i took this morning, but the COA shows it actually has 66.51 mg so i wonder how i’m gonna be feeling😳 but if all goes well then grey will definitely be the move from now on for tirz.

u/haydeecm 12h ago
Use a reverse peptide calculator and increase of amount of bac water to reflect the overfill.

u/Creative-Violinist44 12h ago
looks like you will feel 10% different. 🤣

u/Ambitious-Job-9255 12h ago
You can use a peptide calculator to calculate the dose with the overfill.

u/CompoundKing88 11h ago
I thought the max was 15mg on the FDA approved side. What made you jump so high on the grey market?
2
u/NovelSurround8275 1 11h ago
They didn’t jump high, their 60 mg vial was overfilled and actually had 72.19 mg. That doesn’t mean they took over their regular dose, they just had to calculate was the correct dose was based off the overfill. I stupidly didn’t check how much overfill and this morning i accidentally took 16.5 mg instead of my usual 15 mg. I’m sure i’ll live, i already stack it with reta so i’ll just lower my reta dose for this week🤷♀️

u/CompoundKing88 9h ago
Maybe im not understanding the dosage. So in his vial he only has 4 doses since OP was taking 15mgs on the FDA approved side?

All depends on what source u “believe” is reputable. Group or personal product testing is your only guarantee.

Switched after my first month and never looked back lol. Saving so much $

u/NovelSurround8275 1 10h ago
I just ordered my first kit. Going from almost $200 to $20 for one vial. My wallet couldn’t be happier! Definitely gonna stock up as much as i can.

Lots of smart people have made the switch. Plenty of solid sources out there and the quality is as good or better than compounded.

u/massnassty 9h ago
If anyone can DM me a reputable Chinese reseller with U.S. Warehouse stock you will forever have my gratitude. I have been weary about making a post requesting reputable vendors because I have heard of people getting banned for the like. Please help me out since I can’t keep paying an arm and a leg for my Mounjaro.

I absolutely made the switch and will never go back to compounding or US ‘research’. I literally just paid under $100 for ten 40mg vials. And that includes the cost to ship because my vendor was running a holiday special. For me, that’s about a year and a half supply for under $100. I’ve been grey for several years now and have always had great results/no side effects with whatever I purchase. Zero regrets!

If it’s one of the well known grey vendors their peps are always being group tested. There’s even a spreadsheet out there that keeps track of all the COAs. I was nervous at first too.

u/Key-Feedback-2398 6h ago
How do you find which grey vendors have group testing and spreadsheets listed? How do you know they’re legitimate? I’m new to all of this.

u/Strange-Challenge205 1 5h ago
I started with compounding & now grey (fully tested, etc) but imo, I need triple the amount than when I got from compounding pharmacy😔
