What is high-quality evidence anyway?
If you have spent five minutes on the internet lately, you have probably heard of peptides like Semaglutide. But if you look closer, some of these have huge amounts of data and government stamps of approval, while others are still in the "we are working on it" phase.
To know if a peptide is worth your time, you need to look at its Grade. For example, Semaglutide and Tirzepatide both have an A+ Grade. This means they have gone through massive studies with thousands of people.
Look for the FDA stamp
The most important thing to check is Regulatory Status, which is just a fancy way of saying "is this legal and approved by the government for safety?"
- FDA-Approved: These are the gold standard. Semaglutide (Wegovy) and Tirzepatide (Zepbound) are fully approved. Even Tesamorelin is approved, though strictly for a specific condition called HIV-associated lipodystrophy (a specific type of fat gain).
- Approved Abroad, But Not Here: Some peptides like Thymosin Alpha-1 are used in over 35 other countries but are NOT FDA-approved in the US yet.
The "What Happens Next?" test
One thing people often forget to check is Evidence Gaps. This is where you find out what scientists don't know yet. For instance, with Semaglutide, studies like STEP 4 showed that once people stop taking it, they tend to regain a substantial amount of weight.
With Tesamorelin, the results are similar—it is great for reducing liver fat and belly fat, but the effects completely reverse if you stop using it. If a website tells you a peptide is a "permanent fix," they probably aren't reading the same data we are.
Watch out for the side effects
No peptide is perfect. When looking at data, check for common side effects.
- Semaglutide: About 44% of people experience nausea. It also has concerns regarding the loss of muscle mass.
- Tirzepatide: While it showed a massive 22.5% weight loss in the SURMOUNT-1 study, scientists are still looking for better ways to protect muscle mass during that weight loss.
- Thymosin Alpha-1: Even though it has been used in trials with over 1000 patients, it has been disappointing when used alone to treat cancer.
Talk to a pro
It is easy to get lost in terms like GIP and GLP-1 (which are just types of sensors in your body that help manage insulin and appetite). This is a great one to bring up with your doctor. You can find peptide-experienced physicians in our Find a Doctor directory.
