Sports Research Grass-Fed, Certified Paleo Friendly, Non-GMO and Gluten Free Collagen Peptides Powder, 'XL' Jar, 32oz - Unflavored

Awesome

The package arrived super fast. The product needs no introduction which is well reviewed and one the best Collagen Peptides available.

More expensive than 2 x 10 lb ones.

This is my second time ordered from this seller and they’re absolutely good of this. This collagen’s gives me better result than others.

Got the product in 2 days! Product is exactly as explained although there is quite a bit of unwanted space. The packaging is too big for how much product you get. Thst is the only thing I would comment on.

La poudre de peptides de collagène de qualité supérieure est vraiment pratique à ajouter à mes boissons, café ou smoothies quotidiens. Elle se mélange facilement sans grumeaux et n’a pas de goût, sauf dans les bouteilles ou verre en métal, alors important d’utiliser un verre en céramique ou en verre. Bref, c’est parfait si on ne veut pas altérer la saveur. Depuis que je l’utilise régulièrement, mes cheveux et mes ongles semblent plus forts et ma peau plus lisse et hydratée. La qualité est vraiment au rendez-vous et le format poudre permet un dosage précis selon ses besoins. Un excellent complément pour ceux qui veulent soutenir la santé de leur peau, cheveux, ongles et articulations.

I absolutely love these unflavored collagen peptides. Every morning I put a scoop into a cup and add hot chocolate to it. There is no taste or grittiness and it's super easy on the stomach. I've had no problems whatsoever with this product. I appreciate that the ingredients don't contain any GMOs and are gluten-free. The quality of the product is evident because It's been so beneficial for me. My skin is now super soft and hydrated all the time. My nails have noticeably strengthened and grown over the course of taking these peptides. I believe in this product so much that I even bought the 3.9 oz jar to bring with me when I travel so I don't miss taking a dose. I HIGHLY recommend these peptides.

I started taking these collagen peptides in 2025 and I’m now on my 5th bottle and wow, what a difference! I’ve never had long nails in my life, but after finishing my 3rd bottle, I started noticing real growth. Now my nails grow so fast that I actually have to trim them regularly. They’re stronger, healthier, and don’t break like they used to. I’ve also noticed my skin looks more radiant and healthy, and my hair feels stronger too. The results didn’t happen overnight, but with consistency, they’ve absolutely been worth it. I also take other products from Sports Research and I truly love them all. The quality has been consistent, and I feel confident recommending this brand. I recommend this to everyone at the gym and honestly to anyone who wants healthier hair, skin, and nails. I’ll definitely keep repurchasing!
