Mediator® Phosphatidic Acid

1,500 mg (yielding 750 mg phosphatidic acid)

Phosphatidic acid is an endogenous phospholipid that is suggested to promote muscle protein synthesis, thereby contributing to muscle growth and the maintenance of lean mass.

Mediator® Phosphatidic Acid

Mediator® Phosphatidic Acid

1,500 mg (yielding 750 mg phosphatidic acid)

Phosphatidic acid is a naturally occurring molecule, specifically a glycerophospholipid, found in cell membranes. It acts as a lipid mediator by transmitting signals within cells that are essential for various biological processes, including muscle protein synthesis. Mediator® Phosphatidic Acid is a patented and clinically studied form of phosphatidic acid that has been shown to increase max strength, muscle mass, and fat loss in healthy adults who engage in resistance training [1].

The ergogenic benefits of phosphatidic acid supplementation appear to be independent of protein intake, suggesting that it is an integral mediator of the mechanistic/mammalian target of rapamycin (mTOR) protein complexes that control skeletal muscle protein synthesis [2, 3]. As such, phosphatidic acid ingestion may confer an additive anabolic effect with other muscle-building supplements and adequate protein intake.

Solid product

You’ll buy one, then you’ll be sad it’s sold out. Stuff is solid. I spent the last year in the middle of the desert and dropped 35lb from what I worked hard for. Got him hit the dinner table and the gym. Added this to my arsenal, got me back to what I was moving in a lot less time than I had expected. Won’t be leaving my stack unless it’s sold out.

Love it

I’ve been using for a month and already feeling a difference

It’s good but there are flaws

First like most. The scoop doesn’t match the intended serving size so it lasts 22days and then you are out. Seems like an easy fix TL (come on!)
Secondly, taking supplements consistently sees best results. However with growth if you don’t order a case you will never have any access because it’s sold out ALL the time. So becoming consistent with it means you have to spend a ton to keep a ton on hand, and use more than one bottle a month because it’s not correctly proportioned. Good product when taken yes, but TL could make some changes to help the people out.

Frequently Asked
Questions

Can I take growth with other supplements?

Yes, absolutely. Phosphatidic Acid can generally be taken in conjunction with other supplements, such as protein powders and creatine, without adverse interactions.

Are there any side effects of using Phosphatidic Acid?

Phosphatidic Acid (PA) supplementation has been extensively studied and found to be safe for both men and women. When used at recommended dosages (typically up to 750 mg daily), it may occasionally cause minimal gastrointestinal side effects. However, as with any supplement, it is advisable you consult a healthcare professional before beginning use, particularly if underlying health conditions exist or take prescription medications. 

Is Phosphatidic Acid supplementation safe to take for athletes?

Phosphatidic Acid supplementation is generally considered safe for athletes when taken at recommended doses. Studies have shown it to be non-toxic and well-tolerated (e.g., a daily intake of 750 mg over 8 weeks in healthy college-aged individuals). 

How does Phosphatidic Acid work?

Phosphatidic Acid activates muscle protein synthesis pathways via mTOR signaling, enhancing hypertrophy and strength gains.

How long will It take to see results with Phosphatidic Acid?

The time it takes to see notable results with Phosphatidic Acid supplementation can vary, but significant improvements in muscle growth and strength have been documented within an 8-week period in resistance-trained individuals. Consistency in supplementation (i.e. daily use) and a diligent resistance-training regimen are essential for maximizing the benefits of Phosphatidic Acid.
