What does a "503A pharmacy partner" mean? +
A 503A is a state-licensed compounding pharmacy that prepares medications pursuant to individual prescriptions. Partnering with one means your peptides are compounded under pharmacy licensure and oversight, not produced as unregulated "research" material.
How is each batch tested? +
Every lot is third-party tested by HPLC for purity and Mass Spectrometry for identity, with bi-weekly endotoxin screening performed in duplicate per USP <85> and <161>. A full Certificate of Analysis accompanies every batch.
What are your order minimums and lead times? +
Minimums and turnaround vary by product and configuration. Share your needs in a quote request and we'll confirm exact minimums, pricing, and lead times within 24 business hours.
How do you ship? +
In temperature-controlled, cold-chain packaging with priority shipping nationwide to preserve peptide integrity from our facility to your practice.
Which peptides can I order in my state? +
Availability depends on current FDA and state regulations, which change. Some peptides may be restricted or unavailable in your jurisdiction; our team confirms eligibility for your state during onboarding.
Can you do custom dosing or bulk orders? +
Yes, multiple dose configurations, custom compounding, and bulk pricing for clinics and programs. Specify the details in your quote request.
Are these products FDA-approved? +
