Who said it’s fake and bad product?
Some in the review says that it was a fake product or it contained worms, however it’s totally not true. So I got the parcel today within the expected delivery date and checked the authentication. It found that it was 100% authentic product and the quality of the powder is very good. So, it’s up to you which reviews you want to trust, however don’t just blindly believe whatever you see. Because I was the one who was disappointed with buying this from this seller after seeing the low stared reviews, but the product I got was true one and the quality is good tho.

Effective Mass Gainer With Noticeable Results and No Side Effects
I purchased the 3 kg pack of Optimum Nutrition Mass Gainer and finished the entire pack before writing this review. Over the course of using it, I gained around 2.5 kg in weight, which is a good and steady result.The product mixed well, was easy to consume, and I did not experience any side effects during or after use. Results may vary depending on diet and workout routine, but in my case it worked effectively as a support supplement for weight gain.

Honest review
I used this when I started going to the gym and it worked really well for me that’s why I ordered it for my friends too. On is one of the best and most trusted brands when it comes to protien abd weight gainers. This time I ordered two packs for my roommates- one doesn’t see results probably he drinks and smoke more than he trains 😂 and the other hits the gym only once every 4-5 days. So yeah it’s definot the product’s fault. So just make sure you’re serious, ambitious and consistent with workouts.
