Where to buy AICAR online

We compare AICAR offers across vetted research vendors so you can buy with confidence. Every price above is pulled from a verified, in-stock listing — here's what to look for before you check out.

Compare vendors on price-per-mg rather than sticker price, and confirm a third-party Certificate of Analysis (COA) is publicly available before you buy. The comparison table above flags self-tested-only results and account-required vendors so you can filter those out first.

Stick to vendors with no unresolved legal issues or community warnings, and check that stock and pricing were verified recently — the "last checked" date on each listing tells you exactly when. Products listed here are intended strictly for laboratory research use.

Modern Aminos is a US research-use-only (RUO) peptide vendor requiring account login to view its full catalog. It advertises a multi-stage QA program with QR-linked, per-batch Certificates of Analysis, but an independent vendor reviewer (VialVerdict) reports that HPLC/COA data is actually available on request only and not standard practice — directly contradicting the vendor's own marketing. Independent lab aggregator Finnrick.com has only tested 5 samples (one product, Retatrutide), with 1 of 5 failing purity/fill standards.

AICAR Dosage Guide for Weight + Fat LossAICAR Dosage Calculator

AICAR is a lab compound often called an "exercise mimetic" because it activates AMPK, the body's energy-sensing pathway, similarly to a workout. Researchers explore it for fat burning, glucose uptake, and endurance. Not approved for human use; sold strictly for research purposes.

How to reconstitute AICAR

View guide

The materials you'll need and step-by-step instructions for safely mixing AICAR with bacteriostatic water.

Materials needed

Your AICAR vial (lyophilized)

Alcohol swabs

Bacteriostatic sterile water

3 mL syringes (Luer Lock tip)

25G or 27G needles (Luer Lock). Other gauges may also be acceptable.

Sharps container (optional)

Remove the caps

Remove the caps from both your AICAR vial and your bacteriostatic water vial.

Sanitize the rubber stoppers

Wipe down the rubber stoppers on both vials with alcohol swabs and let them dry for about 3 minutes.

Attach the needle

Take your 3 mL syringe and needle. Twist the needle's plastic hub into the Luer Lock tip on the syringe to secure it.

Draw the bac water

Pull back on the plunger to draw your desired volume of bacteriostatic water. If you overfill, just push the excess back in until you reach the right marker on the syringe.

How much bac water? AICAR typically comes in a 50 mg vial. We recommend 3 mL of bacteriostatic water, though anywhere between 1 mL and 3 mL is acceptable. For larger vials you can use up to 5 mL — more bac water makes microdosing easier, but insulin needles usually max out at 1 mL per injection. That means a lot of bac water might force you into multiple injections to hit your target dose. Unless you're microdosing, 2 mL per vial is a solid rule of thumb.

Insert the needle into the AICAR vial

With the bac water in your syringe, insert the needle into the AICAR vial at a slight angle to avoid pressure buildup.

Use a thin needle: Stick to 25G or higher to avoid damaging the rubber stopper. Higher gauge means a thinner needle.

Release the water gently

Let the water run gently down the side of the vial. Don't inject it forcefully.

Heads up: Sometimes the plunger pushes itself in as soon as the needle enters the vial. Hold the plunger back so you have full control over how fast the bac water enters.

Swirl to dissolve

Avoid shaking. Gently swirl, flip, and roll the vial to dissolve the powder.

Be patient: This usually takes 2 to 5 minutes of consistent swirling, mixing in a circular motion, and gently flipping the vial up and down. The water needs to run through the powder many times to fully dissolve it. Don't shake or get aggressive with it.

Check for full dissolution

The solution should be clear with no visible particles. If it's cloudy or clumpy, wait a minute and repeat the swirling step.

Cap, dispose, and store

Once you're done, cap the needle and dispose of it (ideally in a sharps container). Store the reconstituted AICAR vial in the fridge whenever it's not in use. It will stay good for approximately 30 days.

How We Rank Offers

We don't just sort by price. Here's how each offer's rating actually gets calculated.

Compared Apples to Apples

We score price per mg against other offers of the same dose size, not the sticker price, so a bigger vial doesn't look like a worse deal than it is.

Price Is Only Part of the Score

We weigh price-per-mg alongside vendor rating, COA purity, and account requirements, so a cheap offer from an unproven vendor won't outrank a fair price from a trusted one.

Trust Gates the Top Ratings

A sub-4.0-rated vendor can't earn "Great value," and missing third-party purity data caps an offer out of "Good" or "Great." No price is low enough to buy around it.

AICAR Buying FAQ

Straight answers on legality, pricing, and vendor vetting before you buy. For research reference only.

AICAR (5-Aminoimidazole-4-carboxamide ribonucleotide) is a nucleotide analog studied as an activator of AMP-activated protein kinase (AMPK), the cellular pathway that also responds to exercise. It's sometimes referred to as an "exercise mimetic" in research literature because activating AMPK triggers effects related to glucose uptake and fat metabolism. AICAR is sold strictly as a research chemical, not for human consumption.

Published animal studies typically use doses in the range of 50-500 mg/kg body weight, though these are not directly translatable to human dosing recommendations. Vendors commonly sell AICAR in 50 mg vials intended to be reconstituted with bacteriostatic water for lab and research use. There is no clinically established or medically approved human dosage — any protocol you see referenced online reflects research use only, not a recommendation for personal use.

Preclinical research has looked at AICAR's role in glucose uptake, fatty-acid oxidation, and mitochondrial biogenesis via AMPK activation. Some rodent studies have reported improvements in endurance and metabolic markers without exercise training. These findings come from laboratory and animal research — they have not been established in human clinical trials and should not be interpreted as proven outcomes.

Because AICAR is not approved for human use, there is no established human safety profile or clinical side-effect data. Animal and cell-based studies have noted effects tied to AMPK activation on metabolism, but comprehensive toxicity and safety data in humans is lacking. Anyone purchasing AICAR should treat it strictly as a laboratory research compound, not a supplement with a known safety record.

Lyophilized (powder) AICAR is generally reconstituted with bacteriostatic or sterile water immediately before laboratory use, following standard peptide-handling practices. Unopened, unreconstituted powder is typically most stable stored frozen and protected from light; once reconstituted, most research peptides are kept refrigerated and used within a short window. Always follow your product's certificate of analysis and storage guidance rather than general assumptions.

Reputable vendors provide a third-party Certificate of Analysis (COA) showing purity (commonly ≥98-99%) via HPLC or mass spectrometry testing for each batch. Look for vendors that publish current, batch-specific COAs rather than a single generic document reused across listings. Purity and identity testing is the main differentiator between research-grade and unverified suppliers when comparing where to buy.

In research and biohacking discussions, AICAR is sometimes paired with recovery-focused peptides like BPC-157 or TB-500, based on the idea of combining metabolic and recovery pathways. There is limited formal research on these specific combinations, so any stacking information reflects anecdotal use rather than clinical evidence. As with AICAR alone, this information is for research purposes only.
