Are peptides safe?

The compounds on this site have been studied in people and in animals for years, and some for decades. The fat-loss class has the largest human trials of anything here, with tens of thousands of participants over more than a year. The copper peptide has decades of skin research behind it. BPC-157 and TB-500 have been studied in tissue models and in athletes. NAD+ has been measured in human tissue across the whole of adult life. Where the research is strong, the compound is the core of a protocol here. Where it is thinner, the compound is labelled support and added second.

What is also known is what they do when they go wrong. The fat-loss compounds cause nausea when a dose rises too fast. NAD+ flushes when it goes in too quickly. Injection sites bruise. These are on the results sheet next to each compound, with what to do. The side-effects answer goes through them. Every compound on this site now has its own evidence page: the trials that exist, who was in them, how long they ran and what happened, at the evidence wing, with the gaps set out at what nobody knows yet.

Long-term data on most of these compounds in healthy people is thin, because most of the research was done in people with a condition or in animals. Nobody can tell you what twenty years on a repair peptide looks like, because nobody has the data. This site does not pretend otherwise, and it does not cite a study it has not read.

The compounds are research materials. They are not registered with the Philippine FDA and they are not approved for human use. That is the status, stated plainly on every page, and it is the reason the decision is yours and your doctor's.

Anyone pregnant, breastfeeding or trying to conceive. Anyone with a personal or family history of medullary thyroid cancer or MEN2, for the fat-loss class and the growth hormone axis. Anyone with active cancer, for the growth hormone axis. Anyone with a history of pancreatitis, for the fat-loss class. Anyone on insulin or a sulfonylurea needs their prescriber to adjust before a fat-loss compound is added. The quiz asks all of this, plainly. The stacking checker shows which compounds each medical flag removes, and the bloodwork log keeps the numbers your doctor will want to see.

The medical questions remove compounds rather than warn beside them. If you say you are pregnant, the fat-loss compound and the growth hormone pairing do not appear on your sheet at all, and nothing is shown with a red note next to it hoping you will read the note. What remains is still worth reading, and still worth a conversation with a doctor who knows you.

Every protocol starts with one compound, at its lowest step, alone for a month. That is the safety mechanism underneath everything else: you learn how you respond to one thing before a second is added. The first-protocol guide shows what that month looks like. Take it to a doctor who knows you before you begin.
