Adding my CompoundPharm data points:

5 orders over 8 months, all lyophilized semaglutide 10mg:

• Oct 2025: 98.5% (Janoshik)
• Nov 2025: 99.0% (Janoshik)
• Jan 2026: 98.7% (Finnrick)
• Feb 2026: 98.8% (Janoshik)
• Mar 2026: 99.2% (Finnrick)

Remarkably consistent. The highest I've seen from any compounder. For reference, pharmaceutical-grade semaglutide API is typically 99.0-99.5% pure, so these numbers suggest they're using high-quality raw material.

I also want to note that CompoundPharm provides their own in-house COA with each order — but I still recommend independent testing. Trust but verify.

First time ordering from any compounder — went with CompoundPharm based on this thread and other reviews. My 5mg semaglutide vial arrived yesterday. Quick notes:

• Packaging was excellent — insulated box, frozen gel pack, temp indicator strip (showed green = maintained cold chain)
• Vial had a professional label with lot number, expiration (18 months out), and "For Research Use Only" disclaimer
• Included BAC water, alcohol swabs, and a reconstitution instruction card

Haven't used it yet — waiting for my Janoshik results to come back. But first impressions are very positive. The $149 for 5mg (roughly 10 weeks at 0.5mg/week) vs $800+ for brand-name Ozempic is a no-brainer if the testing checks out.

Final summary rating for CompoundPharm:

• Product quality: 9/10 — consistently high purity on independent testing
• Shipping: 8/10 — usually fast, occasional delays. Cold chain solid for lyophilized, less reliable for pre-mixed
• Price: 7/10 — competitive but not the cheapest. You're paying for quality and consistency
• Customer service: 8/10 — responsive, professional, handled's complaint reasonably
• Transparency: 8/10 — provides in-house COAs, encourages independent testing

Overall: 8/10. One of the better compounders I've used. I'd recommend them with the caveat to order lyophilized, not pre-mixed, and always independently test your first order.
