Best Semaglutide vendors in 2026
Buying Semaglutide: what the field looks like
We track 33 in-stock Semaglutide listings across 11 US retail vendors, and re-read every one of them each night. Ranking below is by cost per milligram, which is the only figure that compares a 5mg vial against a 10mg one honestly.
The cheapest source works out at $2.16/mg against a median of $4.90/mg across the field — 46% less for the same milligram of the same compound. That gap is why this page exists: on Semaglutide the vendor you pick matters more than the size you buy.
The lowest total cart is $34.95 at coffeeandpeppers. That is the cheapest way to hold Semaglutide at all, which is a different question from the best cost per milligram — the two are the same vendor only sometimes.

Bulk and multi-vial pricing
Ranked by cost per milligram. A pack is always a bigger cart than a single vial — the question these answer is whether it is cheaper per milligram, not whether it is cheaper.
Semaglutide vial sizes compared
Vendors sell Semaglutide in 8 sizes. Cost per milligram is not the same across them, so the biggest vial is not automatically the best value.

Semaglutide price history
Median cost per milligram across the field, one point per day we crawled.
How we rank these vendors
Vendors are ordered by cost per milligram of their cheapest in-stock single vial. Nothing else moves the order — not commission, not whether a vendor has a partner programme, not how long we have tracked them.
The score beside each vendor is a listing-quality score, not a purity or trust score. We have no laboratory and we do not test anything. It is built from figures we measure ourselves: where the vendor's prices sit inside each compound's own field, how many compounds they carry, how reliably their listings stay in stock, and how many certificates they publish. Every input is shown beside the number.
Prices older than 48 hours are dropped rather than shown stale, so a vendor missing from this page is usually a vendor whose site we could not read last night.
Common questions
Who sells Semaglutide cheapest right now?
coffeeandpeppers, at $2.16 per milligram and $34.95 for the cheapest single vial. That is across 11 US retail vendors, checked within the last 24 hours.
How much should Semaglutide cost per mg?
The median across 11 vendors is $4.90/mg. Anything at or under that is a fair price; the cheapest we can find is $2.16/mg, and the top of the market runs to $9.57/mg.
Which vial size of Semaglutide is the best value?
Vendors sell Semaglutide in 8 different vial sizes, and the cost per milligram is not the same across them. The table above prices each size separately so you can see which one is actually cheaper per mg rather than per vial.
Are multi-vial kits cheaper?
4 vendors sell Semaglutide in multi-vial packs. They are usually cheaper per milligram and always a larger cart, so they are ranked separately above rather than mixed into the single-vial list.
Do you sell Semaglutide?
No. We sell nothing and ship nothing. Every link goes to the vendor's own store, and some of them pay us a commission — those are labelled on the row, and commission never affects the ranking, which sorts on price alone.
