I have been gatekeeping this and decided to release it to the wider audience, hopefully it will have a big impact with some people trying it out and posting results.
I will be very brief with the explanation.
(summary)
Basically, GAA is approved for animal feed to improve weight gain and more importantly lean mass gains.
The main benefit is that will ~8x the creatine levels compared to creatine
The main downsides are some increase need for methylation so you can supplement with betain for example
And more importantly it's hard to source, you have to go for animal feed or from more expensive lab stuff

I prompted ChatGPT to resume the mechanism and expected gains
But I think it understates the potential gains
Thus, at the “right” dose—typically around 2–3 g of GAA per day combined with an equivalent creatine dose—the improved muscle bioenergetics can lead to notably greater lean muscle gains compared with creatine supplementation alone, all without the direct hormonal actions of anabolic steroids.
After 60 days
Here is a 50% increase in muscle area with GAA in pig loin
Fat thickness is also reduced by 30%
It seems to works as a myostatin inhibitor and myogenic promotor.
Amazingly it isn't known in bodybuilding.
Study:
Human equivalent dose in the study seems low, but math seems correct at a first glance
It's less than 1g/day
I will be very brief with the explanation.

While guanidinoacetic acid (GAA) supplementation can enhance muscle creatine levels and improve exercise performance, it's important to be aware of potential downsides:
1. Increased Methylation Demand and Homocysteine Levels
GAA conversion to creatine requires methylation, utilizing methyl groups from compounds like S-adenosylmethionine. Elevated GAA intake can increase the body's methylation demand, potentially leading to higher homocysteine levels—a risk factor for cardiovascular diseases. However, some studies have reported that GAA supplementation did not significantly raise homocysteine levels in healthy adults. citeturn0search1
2. Gastrointestinal Discomfort
Some individuals have reported transient nausea during the initial weeks of GAA supplementation. In a post-marketing surveillance study, 5.3% of participants experienced such symptoms, though none discontinued use due to these effects. citeturn0search1
3. Potential Neurotoxic and Pro-Oxidant Effects
Animal studies have indicated that excessive GAA accumulation may have neurotoxic and pro-oxidant effects. While these findings are not yet confirmed in humans, they suggest caution with high-dose GAA supplementation. citeturn0search0
4. Impact on Liver Enzymes
Some research has noted changes in liver enzyme levels following GAA supplementation. For instance, a study reported a 13.6% increase in alkaline phosphatase levels after GAA intervention, though other clinical enzymes remained unaffected. citeturn0search4
5. Increased Methyl Group Requirements
GAA supplementation may elevate the body's demand for methyl groups, which could affect overall methyl group utilization and related metabolic processes. citeturn0search7
Conclusion
While GAA supplementation offers potential benefits for muscle performance, it's essential to consider these potential downsides. Consulting with a healthcare professional before starting GAA supplementation is advisable to ensure it aligns with individual health needs and to monitor for any adverse effects.

Both guanidinoacetic acid (GAA) and creatine work by boosting the energy available to muscle cells, but they do so via slightly different routes that can lead to enhanced muscle growth when paired with resistance training.
GAA’s Mechanism and Muscle Growth
GAA is the immediate precursor to creatine. In the body, it’s synthesized from glycine and arginine in the kidney and then converted in the liver (using a methyl group from S‑adenosyl‑L‑methionine) into creatine—the key molecule stored in muscle as phosphocreatine. Phosphocreatine rapidly regenerates adenosine triphosphate (ATP) during high-intensity exercise. This extra ATP helps you push through harder training sessions and recover faster, which over time results in greater muscle hypertrophy. In effect, by boosting creatine synthesis, GAA indirectly improves the anabolic stimulus your muscles receive.
Evidence on Lean Muscle Gains
In one randomized, double-blind crossover trial comparing a creatine–GAA mixture with creatine alone, supplementation with the combined formula (providing about 3 g GAA plus 3 g creatine daily) produced a significantly greater rise in tissue creatine levels. For example, muscle creatine content increased by roughly 16.9% with the GAA–creatine combination, compared with only about 2.0% when using creatine alone citeturn4search0.
This enhanced creatine loading translated into performance improvements—for instance, greater bench press strength. In terms of body composition, one study noted that over a similar training period (typically 6–12 weeks), individuals using the creatine–GAA mixture gained about 1.6 kg of weight (which included lean muscle) compared to around 0.7 kg in those taking creatine alone citeturn4search0. Although these weight differences include some water retention, they suggest that the improved energy bioavailability from GAA can allow for a higher quality training stimulus and, consequently, more pronounced muscle growth.
For context, conventional creatine supplementation alone is well documented to produce an extra 1–2 kg (2–4 pounds) of lean muscle mass over a 12‑week resistance training program in young adults citeturn4news12. The creatine–GAA combination appears to augment this effect further by ensuring even higher tissue creatine levels, which enables harder, more productive training sessions without the direct androgenic (steroid-like) activity seen with anabolic steroids. In other words, the “steroid-like” gains reported with GAA result not from hormonal effects but from optimized energy metabolism and the resulting training adaptations.

In Summary
- GAA Boosts Creatine Synthesis: By acting as a precursor, GAA increases muscle phosphocreatine stores, thereby enhancing ATP regeneration during intense exercise.
- Enhanced Training Leads to Greater Muscle Growth: With more energy available, you can train at higher intensities, promoting superior muscle hypertrophy. Studies have shown that a creatine–GAA combination can yield approximately 1–2 kg more lean mass over a training period than creatine alone.
- Comparison with Regular Creatine: While creatine monohydrate alone typically results in a 1–2 kg lean mass gain over 12 weeks, trials suggest that supplementing with GAA (often combined with creatine) can significantly increase tissue creatine levels (by ~16.9% vs. ~2.0% with creatine alone) and improve strength outcomes, translating into enhanced muscle growth citeturn4search0.
Thus, at the “right” dose—typically around 2–3 g of GAA per day combined with an equivalent creatine dose—the improved muscle bioenergetics can lead to notably greater lean muscle gains compared with creatine supplementation alone, all without the direct hormonal actions of anabolic steroids.
After 60 days
Here is a 50% increase in muscle area with GAA in pig loin
Fat thickness is also reduced by 30%
It seems to works as a myostatin inhibitor and myogenic promotor.
Amazingly it isn't known in bodybuilding.
Study:
Human equivalent dose in the study seems low, but math seems correct at a first glance
It's less than 1g/day
To calculate the human equivalent dose (HED) of the 0.06% GAA dose used in finishing pigs, we use the standard allometric scaling method:
Allometric dose conversion is based on body surface area scaling using the formula:
HED(mg/kg)=Animal dose(mg/kg)×(Animal KmHuman Km)HED (\text{mg/kg}) = \text{Animal dose} (\text{mg/kg}) \times \left(\frac{\text{Animal Km}}{\text{Human Km}}\right)
Using standard Km factors (body surface area correction):
Calculate the pig's dose in mg/kg:
1686 mg105 kg=16.06 mg/kg\frac{1686 \text{ mg}}{105 \text{ kg}} = 16.06 \text{ mg/kg}
Convert to human equivalent dose:
16.06×(2437)=10.4 mg/kg16.06 \times \left(\frac{24}{37}\right) = 10.4 \text{ mg/kg}
For a 70 kg human:
10.4×70=728 mg GAA/day≈0.73g/day10.4 \times 70 = \mathbf{728 \text{ mg GAA/day} \approx 0.73 g/day}
Step 1: Extract the Pig Dosage
- The study used 0.06% GAA in feed, meaning 0.06 g per 100 g of feed.
- Assuming an average daily feed intake (ADFI) of ~2.81 kg for pigs receiving 0.06% GAA (from Table 3), the daily GAA intake would be:2.81 kg×0.06100=1.686 g GAA/day2.81 \text{ kg} \times \frac{0.06}{100} = 1.686 \text{ g GAA/day}
- The average pig weight was around 81–130 kg, with a midpoint of 105 kg.
Step 2: Convert to Human Equivalent Dose (HED)
Allometric dose conversion is based on body surface area scaling using the formula:
HED(mg/kg)=Animal dose(mg/kg)×(Animal KmHuman Km)HED (\text{mg/kg}) = \text{Animal dose} (\text{mg/kg}) \times \left(\frac{\text{Animal Km}}{\text{Human Km}}\right)
Using standard Km factors (body surface area correction):
- Pig Km = 24
- Human Km = 37
Calculate the pig's dose in mg/kg:
1686 mg105 kg=16.06 mg/kg\frac{1686 \text{ mg}}{105 \text{ kg}} = 16.06 \text{ mg/kg}
Convert to human equivalent dose:
16.06×(2437)=10.4 mg/kg16.06 \times \left(\frac{24}{37}\right) = 10.4 \text{ mg/kg}
Step 3: Convert to a Total Human Dose
For a 70 kg human:
10.4×70=728 mg GAA/day≈0.73g/day10.4 \times 70 = \mathbf{728 \text{ mg GAA/day} \approx 0.73 g/day}
Conclusion
- The human equivalent dose of 0.06% dietary GAA in pigs is about 0.73 g/day for a 70 kg adult.
- This dose is within the commonly used range of 2–3 g/day in human supplementation studies.
- For higher body weight individuals, doses would be slightly higher (e.g., ~1 g/day for a 100 kg person).
why buy an expensive Supplement to build 2lbs when you could just buy 2 vials of roids for the same price and gain 20lbs
