Waitlist & Enrollment

- I would like to be added to the waitlist.

Our waitlist is currently open. You can add your email address here. Each month we will invite a group of individuals from the waitlist to begin enrollment, based on the order in which they signed up.

- I am on the waitlist. How much longer until I can join?

The amount of individuals that we invite to enroll each month varies based on multiple internal factors. Therefore, we are unable to give an estimate, but we do appreciate your patience! Be sure to check your email (including spam/junk folders) for a message from support@theslimtheory.com. If you’ve been on the list for a while (from when the list was initially opened at the beginning of 2025) and haven’t heard from us, please email support@theslimtheory.com

Medication & Shipments

- When does my medication ship?

Orders ship the third week of each month via USPS & UPS only, regardless of membership enrollment date. We do not offer expedited shipping or customized shipping dates.

- My medication arrived warm. Is it still safe to use?

Yes, your medication is still safe and effective, even if it arrives warm. While we recommend storing your medication in the refrigerator to help maintain long-term potency, these compounds are not as delicate or volatile as many people assume.

We do ship with ice packs during the warmest months (typically May-August), but this is mainly a precaution—especially in case of shipping delays or extreme heat. It’s completely normal for the ice packs to no longer be cold by the time your package arrives.

As long as your vial is sealed and undamaged, it remains stable and effective, even if it arrives warm. Just be sure to refrigerate it upon arrival and continue following the storage instructions provided in your dosing guide.

- My syringes were missing or damaged. Can I get replacements?

The syringes (and alcohol prep wipes) included with your medication are provided as a free courtesy, not as part of a paid product. Because of this, we do not send replacements or extras.

If your syringes were missing or damaged in transit, you can easily purchase more on Amazon or—depending on your area—at a local pharmacy.

Look for:

  • 1cc insulin syringes
  • 30 or 31 gauge
  • 5/16" (8mm) tip

Here’s a direct Amazon link that meets these specs: https://a.co/d/idQ9GAc
But any syringe with the same specifications will work just fine.

It's also a good idea to keep extras on hand, just in case—accidents happen, whether it's dropping a syringe on the floor while uncapped, bending the tip while drawing up medication, or having one become unusable for any reason.

- My vial doesn't look full—did I receive the correct amount?

Yes, you did receive the correct amount. These medications are powerful and a little goes a long way! Especially at the lower doses, your vial may look virtually empty, but rest assured- there is enough liquid in your vial for your month of doses.

- My GIP/GLP-1 dosage increased from 5mg to 7.5mg, but the amount of units I inject did not. Is this correct?

Yes, that is correct. The compounding pharmacy uses different formulations for the lower and higher tiers of GIP/GLP-1. Although the number of units you inject for 5mg and 7.5mg is the same, the amount of active GIP/GLP-1 you receive in the 7.5mg dose is greater. The formulation has been adjusted to ensure you're receiving the correct increased amount of medication, even if the volume appears unchanged.

- Where are SlimTheory medications compounded?

Our medications are compounded in California in our two partnered compounding pharmacies.

- I'm having an issue with my shipment. What do I do?

If you're experiencing issues with your shipment, please visit our Missing Packages & Medication Replacement Policy for next steps.

- I accidentally spilled one of my doses. What do I do?

We understand that accidents happen. Please refer to our Missing Packages & Medication Replacement Policy for guidance on how to proceed.

Dosage & Adjustments

- I think I need a dosage increase. How do I request one?

We send a Dosage Consultation Email every month, a few days before your next round is scheduled to be filled. Please wait for this email, read it thoroughly, and answer all of the questions accurately. This allows us to properly assess where you are in your journey and determine the appropriate next dose.

- I want to switch the medication I’m on. How do I do that?

If you're considering switching medications, please wait for your Dosage Consultation Email and fill out the appropriate questionnaire. This ensures we can evaluate your progress and make the best recommendation for your needs.

Membership & Account Changes

- How do I cancel, change, or pause my membership?

We understand that your needs may change. If you’d like to cancel, modify, or pause your membership, please contact our support team at support@theslimtheory.com before your next billing cycle to make adjustments to your account.

If you need further assistance, feel free to reach out to our support team at support@theslimtheory.com.

- Why can’t I access the members-only page?

If you're having trouble accessing your members-only content, it may be due to a known issue with Shopify’s new login system.

What’s going on?
Shopify recently introduced a password-free login method that uses a one-time code sent to your email. While convenient, it can lead to problems — especially if you accidentally enter the wrong email. In many cases, Shopify creates a brand-new account without alerting you.

How to check if this happened to you:
1. Go to your account page on our website.

2. Click on the menu icon in the upper right corner of the page.

3. Look at the email address shown there — is it the one you used to sign up with SlimTheory?

4. Check your order history on that page. If your membership order isn’t listed, you're likely logged into the wrong account.

What to do next:

  • Log out of the account.
  • Sign back in using the same email you used when you joined SlimTheory.
