Long term in a variety of cancers, ~80% of the people had remission or stability @dapose
Its found in mankuna honey but the amounts they used here were high at ~500mg x4 a day (in water, just a little 60ml so dont tip pH too high?, with food) + vit c and some b vits, and over a long timeframe. seeing if i can find how long the effect should take. methylglyoxal levels go up with high blood glucose & finding glyoxalase 1 inhibitors to use should increase the effect for a lower dose needed https://www.cancertreatmentsresearch.com/methilglyoxal/ (nice writeup) looking up toxicity, apparently taking creatine can protect healthy cells so this has a selective effect
No significant toxicity (but can take creatine and vit C to enhance effect and protect healthy cells just in case there's toxicity on the heart without)

Acute toxicity study was done with two species of animals, mouse and rat. The maximum dose of methylglyoxal for each mouse was for oral 2 g, for subcutaneous 1 g and for intravenous 0.3 g
All the animals except those used for biochemical studies (see below) were observed up to 90 days after completion of the treatment and were found to remain healthy. No toxic effect on physical condition and behavioral pattern such as hair texture, food intake etc. and death were observed. However, the subcutaneous injections appeared to be painful for both treated and control groups. {diluted in saline too} The pain appeared to persist for several minutes after injection.
In the animals, which received intravenous injections, swelling appeared in the tail and adjoining regions from 3rd week of the treatment. The swelling remained up to about 10 days from end of the treatment.
Treatment of methylglyoxal had no toxic effect on the
functions of liver, kidney and heart and hemopoietic organs
of the rats
- As mentioned before, methylglyoxal had been found to possess strong antitumor activity. Szent-Gyorgyi and his associates and Apple and Greenberg long ago showed remarkable antiproliferative and curative effects of methylglyoxal towards cancer-bearing animals (Szent-Gyorgyi et al., 1967; Egyud and Szent-Gyorgyi, 1968; Apple and Greenberg, 1967).
- In in vivo and in vitro studies with animals and in vitro studies with a wide variety of human post-operative malignant tissue samples, we had observed that methylglyoxal acted specifically against malignant cells and ascorbic acid significantly augmented this anticancer effect of methylglyoxal (Ray et al., 1991, 1997a, 1997b; Biswas et al., 1997). Moreover, we had observed that creatine present in cardiac cells completely protected the animal from any possible deleterious effect of methylglyoxal treatment on cardiac mitochondria (Sinha Roy et al., 2003).
- So, we tested whether these compounds had any curative effect on mice inoculated with EAC cells. The results are presented in Table 7. It appears that at a particular dose the antiproliferative effect of methylglyoxal is augmented in presence of ascorbic acid and further improved when the mice were treated with methylglyoxal in combination with ascorbic acid and creatine. Nearly 80% of the animals treated with this combination were completely cured.
In mice 30mg/kg methylglyoxal slowed tumor development but 30mg/kg + 50mg/kg vit C + 150mg/kg creatine = 0 tumor development,
and regression into tumor free by day 10 but this was in tumors that just started growing
so gram amounts might not be needed if combined with creatine and vit C, was injected i.p so without food if thats tolerable, bumping up because of i.p ~300mg daily might be effective over time combined with 250mg vit C and 1gram creatine, split into 2 doses 6 days a week, maybe adding a couple more grams creatine would work better too

20mg/kg but i.v + vit c + creatine (started on day 7,)
