I’ve tried researching this on my own but haven’t been able to find much. I have Hashimoto’s Thyroiditis & my endocrinologist says I barely have any thyroid left. Would TB-500 help regenerate new thyroid growth & if so where would I inject it?? I plan on taking this along with the BPC-157 (orally) for gut inflammation to see if it can repair leaky gut & digestive issues. Thoughts?
“I didn’t think it would be that bad honestly, but since I weight lift multiple times a weak, this supplement is doing me more harm than good. On a typical weight lifting day my workout is split into 5 sections. After taking 5-htp the night before I barely have enough energy to get through 1 section, and that is a serious problem, because of this I am quitting 5-htp all together.”
In November 2008, the UK Medicines and Healthcare products Regulatory Agency (MHRA) warned the public against melanotan use stating it was an unlicensed medicine that may not be safe. As such, it is illegal to market or supply this product in the UK due to its unlicensed nature. Additionally the MHRA warned 18 companies about selling or advertising the product and closed down 72 websites involving melanotan. By 2013, the MHRA had received 18 reports of 74 separate reactions to the products and reactions have involved stomach and heart problems, as well as blood and eye disorders.

These proteins became of interest in neurobiology with the finding that in the nudibranch (sea slug) Hermissenda crassicornis, the protein Csp24 (conditioned stimulus pathway phosphoprotein-24), with 4 repeats, is involved in simple forms of learning: both one-trial enhancement of the excitability of sensory neurons in the conditioned stimulus pathway,[25] and in multi-trial Pavlovian conditioning.[26] The phosphorylation of Csp24, in common with post-translational modifications of a number of cytoskeleton-related proteins may contribute to actin-filament dynamics underlying structural remodeling of responsive cells.[26]
However, the Food and Drug Administration and its equivalents in other countries have issued repeated advisory notices about Melanotan II, urging consumers to stop using and purchasing this unapproved product. David Carter of the United Kingdom's Medicines and Healthcare Products Regulatory Agency was unequivocal in his denunciation, warning would-be buyers against being "fooled into thinking that Melanotan offers a shortcut to a more even tan." Liverpool John Moores University researcher Michael Evans-Brown cautioned that the peptide may be linked to dyspepsia and various cardiovascular problems, such as increases in blood pressure, while others have noted it appears to stimulate the growth of moles on the body.
Oxytocin has been shown to help people with autism improve their ability to recognize emotion, and Wallum found that the same receptor variant that increases risk for marital crisis in women is linked to social problems in girls. These include trouble getting along with others and a preference for being alone. This and Feldman’s work on oxytocin’s importance for the mother–child bond suggests that the hormone is more involved in the communication component of love between couples than the romantic component of love.
But we have to be just as good at recognizing who we can trust, so the system needs fine-tuned control. That’s apparently where oxytocin comes in. The amygdala, that critical organ for our biological risk response, has a high concentration of receptors for oxytocin. In the second set of those gambling experiments with the volunteers and the trustees, researchers used fMRI to watch the brains of the volunteers as they made their choices. As the levels of oxytocin in the brain went up compared with the placebo group, activity in the amygdala went down! Oxytocin diminishes the amygdala’s ability to send out the message “Warning! Warning! I don’t trust this guy.”
Noteworthy:  Many online sources sell an ineffective product.  Also, peptides are fragile by nature and are not effective when they are taken orally (pills, shakes, etc) because they will be broken down by the digestive process. Instead, peptides are mixed with bacteriostatic water and then injected under the skin with an insulin needle. Peptide injections in this manner are nearly painless and have clinically proven effectiveness.

For example, when a mother is nursing her baby, that stimulation from the breast is going into the brain and causing those oxytocin neurons to fire and release oxytocin directly into the brain. That's much more powerful than what happens with a nasal spray. So I think that, you know, in the future, we may have these drugs that can, in a very potent way, tap into this oxytocin system to treat many different kinds of disorders.

Oral 5-HTP results in an increase in urinary 5-HIAA, a serotonin metabolite, indicating that 5-HTP is peripherally metabolized to serotonin, which is then metabolized. This might cause a false positive test in tests looking for carcinoid syndrome.[28][29] Due to the conversion of 5-HTP into serotonin by the liver, there could be a risk of heart valve disease from serotonin's effect on the heart, as based on preclinical findings.[30][31] However, 5-HTP has not been associated with cardiac toxicity in humans.[22][32][33][34]
