You got that right. Those who use peptides must know how to use it, and not rely on it too much for what they are aiming. If they want to look and feel younger, they need to live healthily. If they want to lose weight, they can take peptides, but they should also know how to hit the gym and cut the carbs.
While it's true that to lose weight you don't NEED peptides, a lot of people will find that they help them to achieve their goals faster than if they didn't use them.
When it comes to losing weight though, its important for you to know the basics before you turn to peptides as I think a lot of people will just think that peptides will work without putting any effort in and thats not the case at all.
