Best Creatine for GLP-1 Users
Stay at 3 to 5 grams and keep lifting. This is not a reason to stop the medicine.
Pete's #1
Thorne Creatine
Thorne has a 5 gram scoop. There's nothing else in it. It's NSF Certified for Sport, the stamp drug-tested athletes look for.
Check the exact size and label before buying. You don't pay extra. I might earn a commission.

More pros and cons
You get a canister and a scoop that make a half serving easy, which is what I'd count for people on a GLP-1 drug who want an NSF canister.
For people on a GLP-1 drug who want an NSF canister, you can lean on NSF Certified for Sport on a plain 5 g powder.
The canister costs more than the pouch for an NSF listing the pouch also holds.
I'd pass if the canister price is the whole reason you'd say no, and I wouldn't pick it for people on a GLP-1 drug who want an NSF canister.
Everyday pick
Momentous Creatine
Momentous has about 90 servings. One scoop is 5 grams. It's NSF Certified for Sport, the stamp drug-tested athletes look for.
Is this the right fit?
You want about 90 servings of plain creatine, not a sample jar.
Keep in mind: Skip it if you need the cheaper month.

More pros and cons
You get NSF Certified for Sport on the 90-serving tub, which is what I'd count for people on a GLP-1 drug who want the 90-serving jar.
For people on a GLP-1 drug who want the 90-serving jar, you can lean on a plain 5 g serving after the June 2026 source change.
The source change will annoy anyone who bought it for the Creapure name, and the small jar is a worse buy.
I'd pass if you need the Creapure logo on the label in 2026, and I wouldn't pick it for people on a GLP-1 drug who want the 90-serving jar.
Everyday pick
Optimum Nutrition Micronized Creatine
Optimum Nutrition has a 5 gram scoop. There's nothing else in it. It's tested by Informed Choice, a third-party lab. An NSF logo on Optimum Nutrition is for their whey, not this powder.
Is this the right fit?
You want a tub you can keep using on a rough stomach.
Keep in mind: Skip it if you get drug tested and need the NSF stamp.

More pros and cons
You get a finer mix in a real tub, at 5 grams of one ingredient, which is what I'd count for people on a GLP-1 drug who want the weekday tub.
For people on a GLP-1 drug who want the weekday tub, you can lean on an Informed Choice listing on the unflavored micronized powder.
The finer grind and the batch program cost more than a plain pouch, and that pouch holds the stricter sport listing.
I'd pass if you need NSF Certified for Sport for a tested season, and I wouldn't pick it for people on a GLP-1 drug who want the weekday tub.
Budget pick
BulkSupplements Creatine Monohydrate
BulkSupplements has a 5 gram scoop. There's nothing else in it. It's NSF Certified for Sport, the stamp drug-tested athletes look for. The bag flops over.
Is this the right fit?
You want the testing stamp and you can live with a bag.
Keep in mind: Skip it if a floppy pouch will make you quit.

More pros and cons
You get 5 grams of one ingredient, so the serving matches the dose I use, which is what I'd count for people on a GLP-1 drug who will use a certified pouch.
For people on a GLP-1 drug who will use a certified pouch, you can lean on an NSF Certified for Sport listing on the unflavored 500 g pouch.
The bag flops over in a gym bag, and measuring a half scoop out of it is annoying.
I'd pass if you refuse to scoop from a pouch, and I wouldn't pick it for people on a GLP-1 drug who will use a certified pouch.

Compare their cost per 5 gHow we chose
By Peptide Pete. Updated .
I checked the ISSN position stand and the NSF Certified for Sport list. The method sits on how we research.
I compare the label, the testing line I can look up, what the same amount of creatine costs, and whether the format fits a daily routine.
Read our full research methodWhat should someone on a GLP-1 drug buy?
The scale is dropping and you're worried the muscle is going with it. Creatine on a GLP-1 drug is still plain monohydrate at 3 to 5 g, taken with lifting. Skip the fat-loss blend. In STEP 1, semaglutide cut body weight 14.9% at 68 weeks against 2.4% on placebo. A DXA subset lost lean mass along with fat. No finished trial has tested creatine in people on a GLP-1 drug. Don't stop the prescription because a tub says so. Skip the loading week if the medicine already upsets your stomach.

The muscle papers aren't a GLP-1 trial
Chilibeck's 2017 meta-analysis of 22 trials in 721 older adults found about 1.37 kg more lean tissue when creatine was paired with lifting (PubMed 29138605). Those adults were not recruited as GLP-1 users. The write-up for that age group is creatine for women over 50. The scale, separate from a prescription, is on creatine and fat loss. If one scoop bothers a stomach the medicine already bothers, read creatine stomach discomfort and stay at 3 to 5 g.
What the weight-loss trials measured
You still take 3 to 5 g a day. That range is the one I keep from the ISSN position stand (Kreider 2017). Lean mass on a scan isn't pure muscle.
Wilding and colleagues, STEP 1, randomized 1,961 adults without diabetes to 2.4 mg semaglutide weekly or placebo for 68 weeks. Mean weight change was -14.9% versus -2.4%, and -15.3 kg versus -2.6 kg (PubMed 33567185).
Mechanick and colleagues read the STEP 1 DXA subset as a 6.92 kg drop in lean mass on semaglutide versus 1.48 kg on placebo, about 40% of the weight lost in that subset (Obesity Reviews, 2024). The scan can't say how much of that lean mass was muscle.
Who should talk to a prescriber first
- If your kidneys are already in trouble, or a medicine hits them, talk to your doctor before you buy. Read creatine and kidneys.
- Pregnant or breastfeeding? I won't pick a tub for you. Ask your clinician.
- If you're a teenager, don't treat this ranking as permission. A parent stays in the decision.
- A label that says third-party tested and never names the lab fails the test. Use the label checklist.
GLP-1 creatine questions
Will creatine stop muscle loss on Ozempic or Wegovy?
You don't have a finished trial that says so. Protein and resistance training are the levers the obesity reviews name. Creatine is a maybe on top of those, at 3 to 5 g, not a replacement.
Should I load creatine while the medicine makes me nauseated?
Skip the load. A loading week is a lot of powder. Stay at 3 to 5 grams a day. If you can't keep food down, call the prescriber before you add a supplement.
Is this medical advice?
No. Adding the powder doesn't rewrite the prescription. Kidney disease, pregnancy, and the medicine itself belong with the clinician who wrote it.
Do I need a special GLP-1 creatine?
No. A blend with stimulants, or a gummy full of candy, isn't a better idea beside an appetite drug. Plain monohydrate is the whole list.
The canister I'd buy beside a prescription
If I could only buy one, I'd buy #1, Thorne Creatine. For the next pick, get #2 and buy the 90-serving tub. Get #3 if a weekday tub matters more than the sport listing.
