I started my training regimen last October, initially using a protein blend that did a great job helping me lean out. However, as my goals shifted, I needed a solution that would help me pack on clean mass without absolutely destroying my monthly grocery budget. That is exactly when I found Transparent Labs Mass Gainer (TLMG).
The Ingredients & Formula
What I really appreciate about TLMG is the total lack of "bull crap" filler ingredients. It’s rare to find a gainer that skips the junk, and the inclusion of a solid dose of creatine monohydrate right in the formula is a massive plus. It has easily become my go-to post-workout shake, and it even doubles as a highly convenient, decent meal replacement when I'm on the go.
The Results
The proof is in the results. Since adding this to my daily routine, I have successfully put on 5 lbs of muscle. As a major bonus, it has actually helped me cut down on my overall supplement spending since it ticks so many boxes at once.
Flavor Breakdown
So far, I have tested two flavors:
Sweet Vanilla: The definitive winner for me. It has a great taste profile and mixes well. Honestly, I find myself craving the sweet flavor profile of this blend, and sometimes contemplate taking another dose just for the taste.
Strawberry Cheesecake: Decent, but I find myself much more partial to the vanilla for daily use. I'm a huge fan of strawberry, but after tasting the Sweet Vanilla flavor, the sharpness of the strawberries leaves a trace of a sour aftertaste.
The Verdict
If you want clean ingredients, no useless fillers, and a formula that actually delivers on muscle growth without breaking the bank, this is a top-tier choice.
Love the taste of it; it gives me so much energy; I feel supper strong; glad I have the monthly subscription; best mass gainer I have ever had:
I’m writing this review as I drink my first shake made with this product. It tastes absolutely amazing, so much that I had to write this. It’s by far the best mass gainer I have ever tried. The scoops are not massive, it mixes very well, does not taste chalky or artificially flavored and has no odd after taste; plus the ingredients are some of the cleanest on the market. Transparent labs has made a believer out of meeee
My first time using it and I will definitely be ordering more, amongst other products to try as well, I have definitely been putting it on my socials for recommendations of trying a newly discovered slamming product. Thank yall so much, and I am excited for my orders to come.
I’ve never used products that brought about such visible changes before. My body grew in such an exceptional way—it was incredible! I loved the transformation and how quickly I could see the difference. However, towards the end, I began to dislike the taste, probably due to consuming it so often. Despite that, after taking a break, I’ll definitely go back to using it. Highly recommend for anyone seeking noticeable results!
I’ve been lifting for 4 year and I’ve had a lot of mass gainers mess up my stomach. This brand has not only help me reach my goals but also doesn’t mess up my stomach
Most mass gainers don’t mixed well and come out clumpy in a blender bottle but this one surprisingly mixed very good with water, it also doesn’t make me feel heavy & bloated . I’ve been taking it for about 1 1/2 weeks and I have been able to add about 2lbs. This is a great product and I will be purchasing more soon.
Great taste!
Easy mix!
Top Grade Quality!
Transparent Labs quality, is in such high regard in my opinion, that I would buy and try any or all of their products, with confidence.
A worry free place to shop for supplements.
Love product
Great for adding lean muscle when used correctly. Can be too much/too many calories if workouts aren’t well matched.
Very good!! I use milk with it too lol
Loved
delicious, havent seen the results i hoped for with it yet, bought second jug of it , for results r tbd
Tastes really good, and even better in a smoothie but shaking it with cold water by itself is good.
Additionally, the macros are awesome and I recommend starting with one scoop then working your way up to 2.
The box that was supposed to contain my order arrived empty. No protein. I contacted USPS who advised to contact the seller. Ive made multiple attempts via email and phone over the past week to get in contact with Transparent Labs with no success. I was a subscription member which states that as a member I receive “VIP Customer Support.” If not receiving any form of communication when there is an issue with a product is VIP, I hate to see what the non VIP support is like.
My package was late. Box was messed up and seal was broken. The tub got broken and most of the powder was gone. I've never had a package show up this bad before. I will not be ordering online again, they don't care how it's shipped. Worst experience ever!
It’s excellent! Taste good ! And doesnt upset your stomach !
No complaints on this one. Great taste and free from all those unnecessary additives. Have added 7 pounds and only half way through the first container.
I have been trying to gain weight since last year as I was underweight. A health coach recommended this product. It's a bit too sweet for me as is so I put a half cup (1/4 of one serving) in green smoothie I make in the morning.
Very good and effective I'm delighted with it the delicious taste..!!
Very great
I've subscribed to this supplement for the main reason of it being one of the cleanest ones I've ever had for my sessions. As far as the flavor goes, it's the best one I've ever had, period! It also arrived in a timely matter.
Great!
Love it
Hands down the best mass gainer I have purchased. The ingredients are high quality and for a mass gainer you only need 2 scoops per serving. The vanilla cupcake tastes great and mixes well if I add additional ingredients like banana, peanut butter, etc.
Mixes well. Taste good. Good ingredients.
It's the best product I've ever bought, the tub came full every dollar I spent it was worth it, I've bought other products, not that they're not good but I get half of the tub and I think I'll buy protein or buy the tub.
