5-HTP supplements are made using an extract from the seeds of Griffonia simplicifolia,a tree native to Africa (2). 5-HTP very rarely occurs naturally in what we eat, but tryptophan, from which 5-HTP is made in the body, is found in a variety of foods. The richest natural food sources include cheese, poultry, eggs, fish, nuts, soy, and various greens.
In persons with Panic Disorders (versus persons without as control) ingesting 200mg of 5-HTP, both groups experienced an increase in salivary cortisol within 3 hours but the persons with Panic Attacks continued to have greater increases after the 3 hour mark; this increased cortisol was independent of any percieved side-effects such as headache, fatigue, perspiration, nausea, etc.
Froemke's study1, published in April, showed that oxytocin temporarily suppresses inhibitory neurons — those that dampen neural activity — which allows excitatory cells to respond more strongly and reliably. “Our hypothesis is that the virgin brain is a blanket of inhibition, and that pairing the pup calls with oxytocin allows the network to be reconfigured,” says Froemke. The hormone may serve to amplify incoming signals and allow them to be recognized as behaviourally important. (It is at least possible, he says, that this same mechanism could explain why some human mothers feel they are uniquely tuned to a baby's cries.)
Research shows that co-administration with carbidopa greatly increases plasma 5-HTP levels. However, several studies have reported that 5-HTP is effective even without a peripheral decarboxylase inhibitor (e.g. carbidopa).[unreliable medical source?] Other studies have indicated the risk of a scleroderma-like condition resulting from the combination of 5-HTP and carbidopa.
Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours and then incubated with 200 μM H2O2 for 48 hours (A, B). The mRNAs expression was examined by RT-PCR analysis. This data were representative of three independent experiments. The bar graph shows the fold increase in mRNA expression compared with control cells. * Statistically significant differences compared with the control, p<0.05.
I don’t recall any literature (research or anecdotal) suggesting that TB 500 showed efficacy with regard to repair of brain tissue. I have however read anecdotal comments regarding N-Acetyl Semax Amidate with regard to increase in BDNF (Brain-derived neurotrophic factor) and the growth of new neurons. I am currently testing N-Acetyl Semax Amidate for its nootropic properties however I have read post in which people suggest that it is “healing” brain damage.
New Turmeric+ with Ginger and Black Pepper. Each bottle of the enhanced Organic Turmeric+ contain 120 capsules with: 607mg turmeric,50mg ginger, 3mg black pepper for enhanced absorption and bioavailability. If you are sensitive to black pepper, you can still buy the original 100% organic turmeric capsules. Combine with Primal Collective Omega 3 EPA/DHA fats for enhanced absorption.

Increasing trust and reducing fear. In a risky investment game, experimental subjects given nasally administered oxytocin displayed "the highest level of trust" twice as often as the control group. Subjects who were told that they were interacting with a computer showed no such reaction, leading to the conclusion that oxytocin was not merely affecting risk-aversion. Nasally administered oxytocin has also been reported to reduce fear, possibly by inhibiting the amygdala (which is thought to be responsible for fear responses). There is no conclusive evidence for access of oxytocin to the brain through intranasal administration, however.
There is no long-term side effects ever reported, but there is post injection effects while using Melanotan 2, typically these effects appear during the first few days of dosing and will become increasingly less obvious as the body adjusts to the peptide. These effects include: hot flush in face, mild nausea, decreased appetite, and increased sex drive. In order to combat nausea, an anti-histamine product can be taken until the body gets used to it. But most common way to deal with this is to take the dose before bed.
Despite these many roles, oxytocin is often reduced to a misleading label. While “hormone of love” may be great for catchy headlines and compelling marketing slogans, they are ultimately misleading. Jennifer Bartz from the Mount Sinai School of Medicine has found that oxytocin can have completely opposite effects on the way people behave, depending on how they view their relationships to other people.

In regards to interventions, one study in treatment resistant depressed persons that combination therapy of 5-HTP with Carbidopa noted that 43 out of 99 (43.4%) patients improved with an average 200mg (variable 50-600mg) dosage of 5-HTP. It has been noted that since Cardidopa is a peripheral decarboxylase inhibitor that can prevent metabolism of monoamines including serotonin that these results are unlikely to reflect monotherapy with 5-HTP, despite being within the 30-45% range sometimes seen with the placebo effect.
