FAQ
Questions about HOLDFAST
Answers for shoppers considering Retainix.
How do I take HOLDFAST each day?
Mix one scoop (30 g) into 8-12 oz of cold water, milk, or a protein shake. Take it once daily, ideally alongside your GLP-1 shot routine, so it becomes an automatic part of your day.
What's actually in the scoop?
20 g whey isolate, 5 g creatine, 3 g HMB, 2.5 g leucine, plus vitamin K2 (MK-7), D3, B-vitamins, electrolytes, and chelated minerals, built specifically around what GLP-1 medications deplete.
Is HOLDFAST safe to take with Ozempic or Wegovy?
HOLDFAST is a daily supplement designed to complement your existing GLP-1 routine, not replace or interact with your medication. As always, check with your prescribing doctor before adding any new supplement.
How is this different from a regular whey protein tub?
Plain whey tubs deliver protein alone. HOLDFAST layers a full creatine dose, HMB, leucine, and vitamin K2 plus D3, the specific bone-protection pair, and electrolytes for hydration on reduced intake.
How many scoops come in one tub?
Each tub holds 30 scoops, a full 30-day supply at one scoop daily. Net contents are approximately 900 g per tub.
Can I pause or cancel my subscription?
Yes. You can pause, skip, or cancel your subscription anytime, no long-term commitment required. Your next order simply won't ship once cancelled.
What if I don't like it or it's not for me?
We stand behind HOLDFAST. If it's not the right fit, reach out to our support team about our return policy and we'll help make it right.
When will my order arrive?
Orders are processed promptly and shipped via standard carrier service. You'll receive tracking details by email as soon as your tub ships so you know exactly when it's arriving.
What does limited tracking mean?
Limited tracking means the tracking page may show only major checkpoints instead of every carrier handoff. Updates can pause between scans, especially while a parcel is moving between facilities or being transferred for local delivery. You may sometimes see extra detail on external parcel-tracking websites by entering the same tracking number. Free shipping options with limited tracking can take up to 30 days.
