About Us
CalPeps is a USA-based company built to change the game of performance enhancement.
We exist to eliminate the false choice between quality and affordability. As the most lab tested source in the United States, we combine extensive third-party testing with strict internal quality control—so customers get consistency they can trust without paying inflated prices.
What started with Peptides has grown into a full lineup of anabolic injectables, oral tablets, and HGH, backed by some of the best domestic pricing available, period.
What our customers are saying
I've ordered from Calpeps multiple times. Everything arrives discreet, well-sealed, and clearly handled with care. You can tell they take quality control and customer trust seriously. As for the products themselves, the quality has been outstanding. I’ve personally seen noticeable improvements in recovery, overall wellness, and consistency compared to other sources I’ve tried in the past. Another major highlight is the customer support team. I received clear, professional, and timely responses. That level of service is rare these days and makes a big difference when you’re a repeat customer.
My overall experience has been seamless.
Calpeps has taken great care and pride in their product. I get my packages fast and with ease, and I have never been without an item. They reply to my questions quickly and are always happy to add an item if I forget something. I've ordered probably 30-40 times from Calipeps. This year, my results have been nothing short of life changing. I have never had a package that was missing a thing or wasn't in the same shape as the package before. VERY CONSISTENT!
I've had nothing but great experiences with Calpeps. Their customer service is absolutely top notch very responsive, professional, and they actually take care of issues without giving you the runaround. Product quality has been excellent. I've been running their Retatrutide for the last 5 months and the results have been amazing, consistent quality and exactly what you expect. I've also used their Anavar 25mg, which I prefer specifically because the 25mg tabs make it easy to split a 50mg daily dose into morning and night dosing — much more convenient and consistent than higher-dose tabs.
Gotta give Calpeps a shout out! I’ve used about every source on SST, and Calipeps has them beat on communication and customer service! I love their labels also! I know a lot of people could care less about labels, but I like a more pharma grade label and their’s is clean and professional looking! Shipping was crazy fast, had my pack the same week I ordered! They have my business for sure! Just wanted to give credit where credit is due!
Frequently Asked Questions
Due to security reasons we no longer provide tracking information, that being said you can always reach out to our support team if you have a question about the status of your order. If it’s been more than 10 business days we can tell you exactly where your package is. Don’t worry, we will always guarantee that your package will be delivered.

Anabolics and powdered form peptides should be stored in a cool dark environment away from direct sunlight. Peptides and HGH once reconstituted with water should be stored in the refrigerator. Avoid freezing your products.
For HGH we recommend 1ml per 10IU of HGH to ensure the product fully dissolves. For peptides, it depends entirely on your desired concentration.
Our Dosage Calculator on the website makes it easy to figure out how much bacteriostatic water to add and how to draw your desired dose on a syringe.
We try to restock popular products within 1-2 weeks, although depending on availability and recent shortages, some products may take longer.
You can go on the product page of out-of-stock products and enter your email address to sign up for restock notifications for OOS products. This is highly recommended because our inventory can sell very fast, with some restocks only lasting a few days.
We can give you broad, general advice, but we would recommend consulting a coach or online forums like SteroidSourceTalk.
