What is RETAIN?

A daily, unflavored powder built to support muscle and strength while you're losing weight. One serving brings together creatine, electrolytes, hydrolyzed collagen, vitamin C, and glycine — the inputs muscle and connective tissue draw on most when intake drops. It's made for the window while the weight is coming off, and for staying consistent well beyond it.

Who is it for?

Women who are losing weight — often with the help of a GLP-1 medication — and want to hold onto the strength and muscle they've built while they do it. If your weight loss is working but your strength feels less consistent than it used to, RETAIN was built for exactly that.

Do I have to be on a GLP-1 medication to use it?

No. RETAIN supports muscle preservation during any kind of intentional weight loss. Women on GLP-1 medications tend to feel the relevance first, because appetite and intake drop quickly, but the underlying need — supporting muscle while in a deficit — applies whether or not medication is part of your routine.

I've reached my goal weight. Is RETAIN still for me?

Yes. The strength you preserve while losing weight is the strength you keep afterward. Creatine, collagen, and the rest of the formula continue to support training, recovery, and connective tissue long after the scale settles. RETAIN is built for the window and for the consistency that follows it.

What's actually in it?

A five-part formula, fully disclosed, no proprietary blend: Creatine Monohydrate (5g), Electrolytes (Sodium 400mg, Potassium 220mg, Magnesium 60mg), Hydrolyzed Collagen Peptides (5g), Vitamin C (250mg), and Glycine (500mg). Every ingredient is there for a reason tied to what the body needs during weight loss.

Is RETAIN third-party tested?

Yes. Every lot is tested by Light Labs, an independent ISO/IEC 17025-accredited laboratory (PJLA #128155), for creatine content, heavy metals, and a full microbiological panel. The signed certificate of analysis for the founding lot is published unedited on our testing page, so you can read the results yourself.

Is RETAIN gluten free and soy free?

Yes. RETAIN contains no gluten or soy ingredients, and the finished product was screened by ELISA to confirm it. Gluten was not detected at a detection limit of 1.0 ppm — the FDA threshold for a gluten-free food is 20 ppm. Soy was not detected at a detection limit of 0.32 ppm. Both results are published on our testing page. If you have celiac disease or a severe soy allergy, note that the product is made on shared equipment and worth discussing with your provider.

Why creatine?

Creatine supports cellular energy and muscle output, which matters most when energy availability is lower than usual — exactly what happens in a deficit. It's the anchor of how RETAIN works.

Can't I just take creatine on its own?

Creatine alone is a strong foundation. During weight loss, though, hydration shifts and connective tissue is under more demand at the same time. RETAIN keeps the creatine and adds the electrolytes, collagen, vitamin C, and glycine that support those other changes, so it can take the place of a standalone creatine in your routine.

Will the scale go up?

Creatine's effect on water is intracellular — it moves into muscle cells. On a loading protocol, around 20g a day, that shift can be large enough to show up on the scale in the first week. RETAIN uses 5g, the daily maintenance dose, with no loading protocol.

Will it make me bloated?

Most reports of creatine bloating come from loading protocols. RETAIN doesn't use one. If you've had a reaction to creatine before, check with your prescribing provider before adding anything new.

What about the tiredness?

This is the part most women don't hear about until they're in the middle of it. When appetite drops, intake drops — and that includes sodium, potassium, and magnesium, not just calories. Electrolytes support fluid balance and normal muscle function, which is why RETAIN includes 680mg of them. It isn't a treatment for fatigue. If tiredness is significant or persistent, that's a conversation for your provider.

Why collagen?

Hydrolyzed collagen supports connective tissue, skin, and joints — the parts of you that change alongside the weight. Skin and connective tissue shift while the weight is coming off, around the arms, the jaw, the inner thighs, and most women don't hear about this until they're in the middle of it. Collagen is here to support that, paired with the vitamin C its synthesis requires.

Does it taste like anything?

It's unflavored by design — no sweeteners, no flavor masking, no sensory load. It's meant to disappear into whatever you're already drinking: coffee, water, a shake. It stirs in without clumping and doesn't change the taste of what it's in.

Does RETAIN contain any allergens?

RETAIN contains no major allergens as ingredients. It's produced on shared equipment in a facility that also processes milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Before each production run, the equipment goes through a full cleaning and changeover procedure that's verified by swab testing — not just visual inspection. The finished product is then screened for gluten and soy, and neither was detected. If you have a severe food allergy, check with your provider before use.

How do I take it?

One scoop a day, stirred into whatever you already drink. No loading, no timing window to manage, no cycling. Consistency is what makes it work, so the easiest approach is to attach it to something you already do every day.

Can I take it with my GLP-1 medication?

RETAIN is a daily supplement, not a medication. It contains no stimulants and no appetite-affecting ingredients, and every ingredient is commonly used in general health routines. If you take a GLP-1 or any other medication, check with your prescribing provider before adding anything new.

How long until I notice something?

RETAIN is built for preservation over time, not a same-day effect. Creatine works by saturating over consistent daily use, so the value is in steadiness rather than a spike. The most meaningful signal isn't something you feel. It's what you don't lose while the weight comes off.

Do I take it on rest days too?

Yes. Creatine and the rest of the formula work through daily saturation, not around individual workouts, so the benefit comes from taking it every day — training or not.

What is the founding batch?

The founding release is RETAIN's launch. The founding price and free shipping apply to the first 500 orders. After that, RETAIN moves to $80 at retail. Founding customers also get their orders first, and first access to future GLYM releases.

What does it cost?

The founding price is $69.99 one-time, or $62/month on subscription. Retail moves to $80 after the founding run. Founding subscribers keep the founding rate.

Why subscribe?

Preservation works over time, so consistent use is the point. Subscription holds the founding price, ships automatically so you don't run out, and can be skipped or cancelled anytime before your next shipment.

When will it ship?

RETAIN is in stock. Orders go out within 1–2 business days, and you'll receive tracking when yours ships.

What's the guarantee?

Every order is backed by a 30-day satisfaction guarantee from the day it arrives. Open it, use it, and if it isn't right for you, email us for a full refund — no process, no justification required. Subscriptions can be skipped or cancelled anytime before your next shipment.
