Wow! Glad I tried this!
It took a couple days before I started to notice a difference, but this stuff works! I've been burning fat faster than I usually do, and I feel better sooner too! I'm coming back from an injury, and this has made turning to training much less of a grind, and a lot easier to enjoy!*

L-Carnitine L-Tartrate Powder
I use this has a preworkout drink. It mixes well and doesn’t taste bad. I’ve also not noticed any stomach discomfort. I’ve only taken this supplement for a little over a week. I haven’t noticed better pumps at the gym but I am more focused and seem to have more energy during my workouts.
I’m happy with the products I’ve received from bulk supplements. I do wish I could find some third party test of their products online. I did research the company on the FDA website and only found one complaint and it was a nonissue. I’m looking forward to trying more products from bulk supplements. *

L-Carnitine L-Tartrate Powder

Great price, High quality
This product works great for increase androgen receptor sensitivity, it Is working for me. Noticed more aggression at gym and pack on muscle faster.*

On 3/31/2018 Trevor said...

Good value
I really like the positive benefits that L-carnitine has to offer and have been using it for years. I prefer powder over pill due to faster absorption but the downside with the powders are that they can smell quite bad. This product wasn't anywhere near as bad, which is a plus. Ultimately, the smell is just part of the ingredient but I liked the fact that this one wasn't bad at all. This is my favorite version of L-carnitine that I have ever purchased and I will definitely be coming back for more.*

L-Carnitine L-Tartrate Powder 100 Grams
I received a 100 Gram sample of this powder to review after my most recent purchase. The powder had white/clear color with the consistency of table salt. It did give off a somewhat fishy odor, but that is the norm for this particular product as I have used it powder form before from other companies. The powder dissolved easily in some warm water and had no taste. I capped the rest of the sample using size 00 capsules. I have been and will continue to take 2-3 caps post workout until the sample runs out. LCLT is know for helping with fat metabolism, mitochondrial support, and increasing androgen receptor density. I will probably buy more once the sample runs out as this is a good value.*

L-Carnitine L-Tartrate Powder
This is a super great product. Help your body to naturally produce energy. I take it before starting my hot yoga class and it helps me to sustain my stamina to the end of the class.*

On 12/8/2017 amy chu said...

Great combination
I was looking for both of the ingredients and found them together at a good price here. The quality is good and the shipping was prompt. I am hoping the L-carnitine keeps well in this mixture. I have used L-carnitine alone in capsules from another source before and it started giving off an offensive odor as it aged.*

On 9/15/2017 Christopher said...

Excellent purity and quality. I take 1.5 grans a day. I did feel a difference.*

Awesome product
It has a fishy smell, but dissolves easy and taste isn't bad. It really works good for pre-workout. Definite energy boost and makes you feel good. I love this stuff and will continue to buy it from BS. You can't find a pure product like this any cheaper. Added benefit burns body fat and enhances my endurance at the gym.*

On 5/24/2017 Jasen said...

This product is helping me with my workouts a lot, I'm glad I purchased it!*

On 5/17/2017 RENE said...

High Quality for Sure
I was using another company where the product didn't list how much l-tartrate was in it. The product was very "tart" and i could tell it had probably more tartaric acid in it then l-carnitine. Now the product from lists the ingredients and how much per milligram. I could tell by the taste when i drink it that there is way less tartaric acid in there product then the last one i was using. I am extremely happy with and will be using them for all my supplement needs. Great service and exceptional product. *

On 5/15/2017 Matthew said...

Seems effective so far
This seems more effective than carnitine-fumarate which I have used in the past. I take 1/2 teaspoon mixed into water on a empty stomach first thing in the morning. Seems to mildly boost metabolism and body temperature, also quite effective at reducing delayed onset muscle soreness after an especially taxing workout.*

On 5/10/2017 Charles said...

Nearly Essential
There's a noticeable difference during contest prep between having L-Carnitine L-Tartrate and running out. Deffinitely a staple!*

On 4/11/2017 Jason said...

Very Pleased
Another product that I love. Everything I've ordered so far has been a home run. When you're getting pure supplements without all the added fillers it makes it extremely easy to add to your routine. This is yet another product I'll be buying again.*

On 3/23/2017 Mike said...

Adding for heart health
I decided that this would be a good supplement for my heart health. Using recommended dosage. A lot of good literature about l-carnitine and supporting a strong, lean heart.*

Carnitine L-Tartrate
Bulk Supplements' Carnitine L- Tartrate is a quality product for the best price around!*

On 11/5/2016 Chris said...

Just added to pre-workout
I just started using L-Carnitine Tartrate in my post-workout mix along with 30-40g of dextrose (per Jim Stoppani, Ph.D.) and whey protein. It dissolves easily in water and does not overwhelm the taste of any flavoring. Bulk Supps is the cheapest I have found and fast delivery to my door.*

On 11/3/2016 Robert said...

Mixes well and doesnt add too much of a taste. I mix it in my post workout for ease and love it*

On 10/30/2016 Tyson said...

Loved it
I take L-Carnitine L-Tartrate to to ease my recovery time. As an older lifter it's become an essential part of my supplement routine and this product is a good as it gets!*

Pre workout ingredient...
Best feeling ever gotten from BulkSupplement ingredients!!! Combined several BulkSupplement supplements for the greatest sustained energy, sustained pump, sustained increased blow flow, and recovery ever experienced. Also mixed into my pre I had; 150mg pycnogenol (which BulkSupplements sells in powder and pill as "Pine Bark Extract"), 2grams of Beet Root Juice Powder, 900mg of Tart Cherry extract, and 6mg of Melatonin. I even had a friend try the pre stack I combined to ensure legitimacy and it is verified that I was just crazy these last two workouts. Try it, BulkSupplements gave me the best deal and quality of product.

My order:
L-Citrulline DL-Malate 2:1 - 500g Pure Powder (6-8grams per pre)
Beta Alanine - 250g Pure Powder (1-4grams per pre(total 4grams/day))
Creatine Monohydrate - 500g Pure Powder (1-5grams per post (total 5grams/day))
L-Carnitine L-Tartrate Powder-250g Pure Powder (1-4grams per pre (total 4grams/day))
Green Tea 50% Polyphenols - 250g Pure Powder (1-2grams per pre)
D-Aspartic Acid (DAA) - 250g Pure Powder (3grams per post)*

On 10/7/2016 Jason Cherry said...

Great product for excellent recovery rates. I feel better rested and I perform better on my higher rep sets.*

On 10/5/2016 Jamie said...

Great for Fatigue Management
I take 2 grams of L-Carnitine L--Tartrate post workout with about 70 grams of simple carbohydrates. I then follow that up with 50 grams of a whey isolate. Recovery time is top notch and not to mention the pumps are incredible.*

On 9/23/2016 Jamie said...

L-Carnitine L-Tartrate is right on target
The product arrived within 3 days.On second day after taking about 1g I noticed a change in energy, to my plesant surprise. I like the product and the sour taste does not bother me. I would reorder it.*

This is good for recovery and it enhances any test booster, Bulk Supplements has added another good product to their line-up!*

On 7/7/2016 Tim said...

Very solid
Much cheaper to buy from here than ordering a post drink supplement. Appreciate the directions saying that it has a synergistic effect with COQ10.
Here's hoping that the purity is on par with its other products.*

On 6/28/2016 Eugene said...

Results already
Love the service at BulkSupplements. I live in Los Angeles and the products are always delivered within 1 or 2 business days even though I choose the USPS shipping option. The carnitine tartrate powder seems to be working. Took it on a 6 hour hike and it defintely helped burned more fat versus other times I've hiked the same trail. *

On 6/2/2016 dalton said...

One of the Best
I've been a long time fan of carnitine tartrate, I think it's one of the best supplements you can take and is on the same level as creatine and beta alanine. It's not something you can feel working, but you will notice less soreness and increased endurance after about a week or two. It also helps to keep fat gain to a minimum on a bulk and increase fat loss during a cut. Has a handful of other good benefits as well. Shipping was fast. Bag was strong. Price is great, ordered 1kg. Will buy again.*

On 4/13/2016 Dustin said...

Game changer
This L-Carnitine Tartrate powder was exactly what I needed in my preworkout powder to give me the extra boost I was looking for. After using it for a couple days, I noticed better endurance and a bigger pump than normal. I think I'll continue to purchase in bulk and make my own preworkout, and will L-Carnitine Tartrate will definitely be in the cart.*

On 3/2/2016 Craig said...

Great product
I ordered the 500g bag of LCLT and am very happy with my purchase. First, it got to TN in 5 days. The bag is high quality and air squeezes out easily without making a mess of the powder. The closing system is a little hard to use at first but if you bend the top of the bag to a 90 degree angle, it seems to close a lot easier. The product is definitely quality, I have been taking 1.5g pre and post workout to reach clinical dose. Taking it "to the dome" is a lot easier than mixing it with water as the taste is extremely sour. I can't note the effectiveness but will follow up in the upcoming weeks.*
