Great value ### ⭐⭐⭐ Do I feel anything or supposed to? *by T***S on 28 May 2026* I feel no difference in my system after taking these. Weight loss? Nope. Duration un ok, sleep quality nope but easy to swallow. There ### ⭐ Buyer beware! *by A***S on 17 April 2026* I started taking this supplement mid year 2024 to replace the nitric oxidie supplement I had previously been taking, but became unavailable. At first the supplement was a decent, cheaper replacement for the high quality supplement I had been taking. During late fall of 2024 is where things unknowingly started to go south. I started developing itchy areas on my body, starting on one of my ears and the stomach area. It would come and go but it was extremely irritating. I purchased some itch creams and antibiotic ointments thinking I had gotten into something in the yard or bitten by a spider or other insect. The itchy areas also started developing sores. After treating the areas the symptoms would dissipate after a week or so, leaving me to think the issue is resolved. However, the itching would start back up in other areas on my body, moving to my chest, the top of my shoulders and neck. The itching became so intense that it would wake me up in the middle of the night. I would literally feel like ripping my skin off it itched so bad. It was unlike any itching I had experienced before, down to the bone itching that scratching would not touch. Think of the worst itching mosquito bite x 10 that you can't get to under your skin. I tried every itch cream known to man and none of them would give me any relief. This went on for months where the itching would come and go from area to area. Every time an area would stop itching, I would think it's gone away, but within a few days a new area would start. I finally decided to go see my doctor and they could not identify what it was for sure and prescribed me a strong steroidal cream. This helped, but did not fix anything. I went back to the doctor and was referred to a dermatologist. I had itched my shoulder area so much that the skin dried out and turned leathery, which he mistook for eczema. It didn't even look like eczema but he didn't know what was causing the itching so he threw antibiotics and more itch cream at it which did nothing at all to solve the problem. After going through 4 large tubes of prescription steroidal itch cream, 60 antibiotic pills and 3 trips to the doctor I decided they weren't going to get to the root of the problem and to cancel my 2nd followup appointment and take matters into my own hands. I became desperate for any relief, I hadn't slept through the night in a year, was constantly ripping my skin off and putting creams on. I tried ivermectin to see if I possibly had parasites, that didn't work. I tried other natural remedies and nothing would help. One day recently I decided that I had to eliminate any other possibilities and stopped taking this nitric boost. After the second day of not taking the nitric boost I noticed that the itching had reduced to one area on my chest. This kept going on for 3 more days and then the next night for the first time in over a year, I was not woken up by severe itching.. With each day removed from the nitric boost, my symptoms were reduced and by the 7th day I had no more itching. I have no doubts after a year and half long struggle that this supplement was causing all my issues. I have not slept well in over a year, spent hundreds of dollars trying to find relief and a solution to find out that this supplement was the culprit. I cannot stress enough the hell I have been through. Imagine getting woken up every night for over a year and literally wanting to rip your own skin off. Maybe it's my fault for not thinking of it sooner but I have taken supplements for two decades and have never had any issues until this one. I would never recommend this product to anyone because of this. Don't even take the chance, this issue caused me mental and physical hardships that's going to take me a while to recover from. I literally had open sores bleeding everyday from itching so much. This product needs to be discontinued until fully evaluated as I am not the only one that has had allergic reactions ## Frequently Bought Together - Extra Strength Nitric Oxide Supplement 3X Strength L Arginine, Citrulline Malate, AAKG, Beta Alanine - Premium Muscle Supporting Nitric Booster - Natural Energy & Heart Health Support - 240 Capsules - Nutricost Nitric Oxide Booster 2250mg, 180 Capsules - 750mg Per Casule, 60 Servings - Gluten Free and Non-GMO - Snap Supplements Prostate Health Support Supplement, Saw Palmetto for Men Plus Stinging Nettle Root, Magnesium Citrate, Zinc and Plant Sterols, Supports Male Urinary Tract Health, 90 Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/439498689-extra-strength-nitric-oxide-supplement-l-arginine-3x-strength-citrulline](https://www.desertcart.sg/products/439498689-extra-strength-nitric-oxide-supplement-l-arginine-3x-strength-citrulline) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-12*
