How to Choose Your First Peptide: A Doctor on Goals, Expectations and Starting Slow

Start with the goal

A lot of people come in with a list of peptides that they’ve read about or heard about on a podcast, which I get, but I’d rather start with the goal in most cases. If you’re trying to lose weight or work on sleep or skin or muscle mass, all those things are going to lead us down different paths.

Once we know where we’re trying to go, the list gets pretty short, pretty quick as far as how do we get there. Peptides grouped by goal are in what peptides should I take.

Health history and current medications

After that, health history and your current medications are important. Those can rule some things out and play a role in a lot of peptides that we work with. Then we can help you to pick options that are going to be the best fit for you.

Mistake one: unrealistic expectations

The biggest mistake that I see beginners make, actually two things come to mind. Number one, people come in and they have unrealistic expectations. They think that there’s going to be dramatic changes overnight, which is not usually the case. And then they get frustrated if they don’t notice impact almost immediately.

Our goal is to give people everything that we can and be as transparent as possible.

Mistake two: too much, too fast

The second mistake that I see people make is trying to go too much, too fast. They think they want to start four or five peptides at once. And while that can be done in some combinations, it’s typically better to start with less, one or two, and also to start in a lot of cases at lower doses and then titrate up. This is fairly true for pretty much all medications.^[1]

If we start multiple things at once and then you have a side effect, it may be tricky to tease out which thing is giving you the side effect.

That doesn’t mean that we can’t combine four or five peptides. We certainly can, and we do, but in general, it’s better to start lower and slower and then build from there. The prescribing provider sets each dose. Dr. Snipes covers pairs to avoid in how many peptides you can stack.

Why a blend counts as one

I will mention that there are some exceptions, because we do prescribe some combinations and blends. For example, BPC-157 and TB-500 are offered in a combo. So when it’s a situation like that, those are peptides that are intentionally designed to work together. So in that way, I consider them more one versus multiple things.

In lab studies the two act differently: BPC-157 on tendon cell migration and survival, TB-500 (thymosin beta-4) on cell migration and new blood vessels.^[2][3]

But again, we try to give people as much information as we can. For the first weeks of injections, see Dr. Snipes on technique, timing and storage.

How to get your first peptide

Human-use peptides need a prescription and a 503A pharmacy. At Rx Peps Direct, a licensed provider reviews your history for a $39 medical review per order, covering up to three peptides. If approved, a licensed U.S. 503A pharmacy prepares it pre-reconstituted and bills the medication at wholesale, in 28 states plus Washington, DC. Browse peptides or read the beginner protocol guide.
