Every offer, by form

None of these listings is a vial, so each form is shown in its own section and none is priced per milligram.

Capsules and tablets

Priced per bottle. The size shown is what the listing states, usually one capsule or tablet, so a price per milligram would not compare with a vial.

Three things the price does not tell you

A cheap sticker price only counts if the package is right.
Labeled amount

The label is a claim, not a measurement

The amount printed on the pack or spray bottle is the vendor's claim, not a lab measurement. Compare offers by what each label states before judging value.

Landed cost

Shipping and card fees are not in these numbers

Shipping is often flat, so it hurts small orders most. Several vendors add a card fee and discount for crypto. Two offers a dollar apart can swap places at checkout.

Package size

Bigger packages look cheaper and expire just as fast

Compare capsules and tablets by the amount per unit and the count per pack, sprays by their stated contents and amount per spray. A larger package only saves money if you can use it within the product's labeled shelf life.

What you are actually buying

Regulatory status changes what a price means.
GB-115 vial, mock product photograph
Regulatory status

Research only

Not approved in the US and, as far as the published record shows, not approved in Russia either. It came out of the Zakusov Institute of Pharmacology in Moscow, where a related program also produced Noopept. The human evidence is a single study in 31 patients with generalised anxiety disorder, using 1 mg tablets for 21 days, whose stated aim was to determine an effective dose and assess safety and tolerability. Vendor listings describing a completed phase 3 program are not supported by anything we could locate.

What that changes

Nobody stands behind a research product

There is no pharmacist behind it, no dispensing record, and nobody on the hook for what is inside the pack or spray bottle. The lab report is the whole quality system, which is why it sits next to the price here.

Research use only is a claim the seller has to keep making. A vendor that adds dosing instructions, health claims, or personal-use wording has stepped outside the framework it relies on, and that says something about the seller.

What customs and carriers do varies by state and by shipper. This describes how these products are sold and is not legal advice.

Before the vial arrives

What actually shows up, and the vial math that decides which size is the better buy.

Storage

Frozen dry, refrigerated wet

Freeze-dried powder keeps for a long time in the freezer and for months in the fridge. Once liquid goes in, most people work to about 28 days in the fridge, away from light.

Mixing

Bacteriostatic water and insulin syringes are extra

What arrives is powder in a sealed vial. Water goes down the inside wall rather than onto the powder, and the vial is swirled instead of shaken. Neither the water nor the syringes are in the prices above.

Vial economics

The bigger vial is only cheaper if you finish it

A larger GB-115 vial costs less per mg and expires on the same schedule once mixed. The saving is real only when the vial runs out inside that window.

Nothing on this page tells you what to take. Full walkthroughs live in the guides.

How this table is built

What decides the order of the rows, and who gets to be in them.
Ordering

Cheapest per mg first, and nothing else

Rows sort on one number. There is no combined score and no weighting, so no vendor can be pushed up the table by a rating you cannot check.

Inclusion

Doing badly does not get a vendor removed

Vendors that publish nothing stay in the table, marked. Taking them out would make the market look tidier than we found it.

Prices

Every price has a date on it

Prices are read off public catalog pages and saved with the date. If a check runs late the row says so instead of showing an old price as current.

Money

Sorting never reads who pays us

Commissioned links are marked on the row and listed on the disclosure page. They never move a listing up or down the table.

How these prices are collected

Prices on this site are read from vendor websites on the dates shown. A starting tag means the vendor publishes only a from price for that product. A wall means the seller hides the price behind an account, and we publish that fact rather than hide the gap.

We report prices and never rate or score an offer. There is no value grade, no ranking of vendors by our opinion. A row carries its size, its price, its price per milligram, and any plain fact about the listing worth knowing.

When a vendor's site disappears, its rows stay in the tables as a dated record, drop out of every count, price range and ranking, and lose their links. Ninety days after a vendor's site disappears, its rows leave these tables and remain in our records.

Some vendors pay this site a commission when you buy through our links. Every one of those links is marked, and every vendor with that arrangement is labeled on the vendor page. Commissions never change the prices we show, the order of any table, a vendor's badge, or anything in the audit record. The data is collected the same way for every vendor, paid or not.

We accept no payment for coverage, placement, or ratings. Warning letters come from fda.gov. If a paying vendor earns a bad mark, the mark stays.

Questions about buying gb-115

Cost, sizes, and how this table works.
How much does GB-115 cost?+

We track 2 listings across 2 vendors, which is too few to publish a reliable per milligram range. The table above shows every price we have read.

Why is the same product so much cheaper at one vendor?+

Package size, sale cycles, payment method discounts, and how much testing evidence a seller publishes all move the number. A cheap price is only cheap if the product holds what the label claims, which no price column can tell you.

Do you make money if I buy?+

Sorting never reads whether a vendor pays us. Any commissioned link is marked on the row and listed on the disclosure page, and it never changes where a listing lands in the table.

Is gb-115 legal to buy?+

Not approved in the US and, as far as the published record shows, not approved in Russia either. It came out of the Zakusov Institute of Pharmacology in Moscow, where a related program also produced Noopept. The human evidence is a single study in 31 patients with generalised anxiety disorder, using 1 mg tablets for 21 days, whose stated aim was to determine an effective dose and assess safety and tolerability. Vendor listings describing a completed phase 3 program are not supported by anything we could locate.

How current are these prices?+

Every price is read off a public catalog page and stored with its date; this compound was last read Oct 18, 2026. Nothing is overwritten, so a stale row says so rather than pretending to be current.
