Frequently Asked Questions

What are peptides?

Peptides are short chains of amino acids that act as natural messengers in the body. They help regulate metabolism, cellular repair, immune health, and hormone balance.

Are peptides safe?

Yes. When prescribed and monitored by qualified providers, peptides are considered safe and effective. At Peptides First, your plan is physician-guided and closely monitored to ensure the best outcomes.

Where do the peptides come from?

We only use top-rated, U.S.-based 503A compounding pharmacies that are LegitScript certified. This guarantees your peptides are produced to the highest standards of safety, quality, and compliance.

How do I receive my peptides?

Once prescribed, your medications are shipped directly to your door in secure, temperature-controlled packaging from our partner pharmacies.

Is this only for weight loss?

No. While many peptides help with appetite control and fat metabolism, they also support energy, sleep, recovery, skin health, and overall wellness. Our approach is designed for whole-body results.

How long does it take to see results?

Most women notice changes in appetite, energy, and sleep within a few weeks. Sustainable weight management, improved recovery, and deeper wellness benefits build over 2–3 months.

Do I have to inject peptides?

Not always. While some peptides are injectable, others can be taken orally, nasally, or topically. Your provider will recommend the best option for your goals.

Will I need to diet or exercise?

Peptides are not a quick fix—they work best when paired with healthy lifestyle habits. That doesn’t mean extreme diets or intense workouts—just balanced choices that support your biology.

How do I get started?

It begins with a simple consultation. We’ll review your health history, goals, and preferences, then design a personalized plan that’s delivered to your door and monitored by our team.
