True Cost of Peptides

The Real Cost of Peptides: A Conversation on Total Cost of Ownership (TCO)

Lately, I've seen a lot of debate about pricing and even more posts asking for vendor recommendations. One topic that doesn’t get enough attention — but probably should — is Total Cost of Ownership (TCO) when it comes to buying peptides for "research" purposes.

When sourcing peptides, there’s more to consider than just the sticker price. Factors like ease of ordering, speed of delivery, payment methods, and most importantly, testing and verification all contribute to the real cost.

Let’s break it down with an example using Tirzepatide:

Scenario 1: Self-Testing “Cheap” Peptide (Least Risk if you get what you bought)​

• Tirzepatide @ $0.50/mg
• 10 vials of 30mg each (300mg total): $150
• Shipping: ~$50
• Jano test + shipping: ~$350
• 1 vial used for testing, leaving 270mg usable

Net Cost: $550 for 270mg = ~$2.04/mg

Scenario 2: Well-Known Seller with Verified Group Testing (increased risk that you did not receive what you bought)

• Tirzepatide @ $0.85/mg
• 10 vials of 30mg each (300mg total): $255
• Shipping: ~$50
• Many 3rd Party tests and Group Tests (does not guarantee that's what you get)
• 300mg usable (no loss)

Net Cost: $305 for 300mg = ~$1.02/mg


So while the first source looks cheaper on paper, the actual cost per mg is nearly double once testing is factored in. That's the value of TCO: it looks at the real price — not just the invoice.

If you buy from a completely unverified vendor and skip testing entirely, you might get lucky… or you might end up with the wrong peptide, poor purity, or worse. That’s not just a financial risk — it’s a health risk.

Why Testing Matters​

• Verification: Are you actually receiving what you ordered? Mix-ups do happen — and they can be dangerous.
• Purity: Is it 98%, 99%? Consistency matters.
• Content: Is there overfill? Underfill? A few milligrams off can significantly change your actual cost per mg and your dosing accuracy.

There are no guarantees in this, only choices you make to *reduce your risk. Testing (either personally or via trusted group buys) is essentially insurance for your wallet, body, and peace of mind. (*there will still be some thing that can go wrong)



I’d love to hear more thoughts or experiences with this. TCO is important when considering sourcing decisions.

This is why I like group buys. I'll buy from the SRY's, the QYC's and the Nexaphs or Debs out there, but group buys get a better price per mg, and they include testing by Janoshik or the other guys. Safety first when were putting things into our bodies.

A well organized group buy is worth the premium over the cheapest vendor. I'd much rather have a referee (the GB organizer) in case things go wrong, than for me to convince a random vendor that their pep tested poorly and should be replaced, etc.

I’m sorry, new to this… what is a group buy?

When a group of people get together and buy several kits from same batch, pitch in on sending a few for testing and split costs. resulting in a test of that batch while all paying a fraction of testing costs and sacrificial peps

First, welcome. Second, how grey do you think you wanna go? To make it easier, what is your Discord and Telegram handle?... If you have no idea what I'm talking about, buckle up... The ride is about to take off!

My user on both is jseven7777777, I can only imagine how difficult this would all be if I had no clue what you were talking about

I’m new to grey, tired of compound prices… looking into SRY and amolist currently, where is that on the greydar

Both have had good and bad events, but they would rank among most reputable. Get in with a good group (you'll see some pop up from time to time) and get your own testing, or put some blind faith in the vendor (most of us have at some point). If you do, don't reinvent the wheel and go with some low bidder who hit you up via dms. That could be ugly.

Read up, join Qualligator.com too, and start out with the vendor list here. That should get you nice and grey...

I thought this would also include the accessories, equipment and time

At the end, given how much time and effort I did put in, I am not break even yet, but what I like is freedom.

I don't have to depend on a pharmacy or a doctor filling my prescription. I can also try other things without much more expenses (in time and materials).

Freedom is definitely the first reason I'm doing all that

If you are buying 1 kit at a time (I know that many people can't afford more than one at a time), then you REALLY should be looking at either getting from a high quality source that has peer tests already done/in process because if you can only afford one kit, you most likely can't afford independent testing most likely.

For all other situations, not buying in some level of bulk is insane IMO. You have a "fixed" cost of testing, regardless of how large your order is, but the more you purchase spreads that testing over more vials/kits so the $/mg is much lower. Not to mention free shipping.

I've made 2 purchases in my little over a year being in this community, my first was 4 kits of T60 from Amo and got it for ~$500 a kit, and testing 1 vial out of each kit, bringing my overall cost down to (including vials/BAC water/syringes/filters/etc.) to $1.24 per mg.
Cost Breakdown:
- Product - $2092.00
- Group Testing - $249.00
- Extras (I bought like 2X what I ever needed): $342.63

$2683.63/2160mg = $1.242

My other purchase was 2 Kits of 30mg Reta from GYC for $636 total, or $1.13/mg. I had worked with some people in GYC to make sure that if I was not chosen to participate in their post shipment testing, that I could throw in $100 for a test vial of my own product. Luckily I was one of 2 people to volunteer, so the cost was just shipping (I think was like $12 or something). Still have a TON of supplies from my first go around.

$648/570mg = $1.136

I ALWAYS pay extra for alipay so that I can dispute if needed (haven't had to thank goodness)

If we repeated the T60 now, with prices being around $0.50/mg, then I would probably be around the $0.80/mg rate after testing and supplies

TL/DR, Don't buy single kits if you can help it in any way, you will save a LOT of money overall (sometimes close to 30-40%) and also, research a HELL of a lot before buying, it will also save you a lot of time/headaches.
