Those metabolic outcomes are excellent and track closely with published trial data. The 17-18% body weight reduction over 10 months at 10-15mg tirz dosing is right in the expected range (SURMOUNT-1 showed 20.9% at 15mg over 72 weeks).
The lipid improvements are particularly noteworthy — LDL down 27%, triglycerides down 43%. Those are statin-like improvements from a GLP-1/GIP agonist. Your cardiovascular risk profile has meaningfully improved.
One suggestion: add liver enzymes (ALT, AST) to your monitoring panel if you're not already. There have been rare reports of transaminase elevations with GLP-1RAs, particularly in the context of rapid weight loss and fatty liver disease resolution. Not a concern per se, but worth tracking.

Good call — I do track ALT/AST. Both have actually *improved* over the period:
- ALT: 48 → 28 U/L (was mildly elevated at baseline, likely NAFLD-related)
- AST: 34 → 22 U/L
My doctor is aware I'm "taking tirzepatide" (I didn't specify the source) and is genuinely pleased with the metabolic improvements. He actually said "whatever you're doing, keep doing it." If he only knew the source was a Chinese chemical supplier and not Eli Lilly... but the peptide doesn't know where it was made. Molecules are molecules.

Does QSC offer any loyalty discounts or perks for repeat customers? $3,000+ over 10 months makes you a valuable customer. Have they recognized that at all?

Informally, yes. After my 6th order, my rep started proactively offering me the "next tier" bulk discount even when my order quantity didn't technically qualify. For example, my 10-vial orders now get priced at the 20-unit tier, saving me about $20-30 per order.
After the short-shipment incident (Order 6), I got a 10% discount code as a make-good that I've used twice. And on Order 9, my rep threw in 2 free BPC-157 vials as a "loyal customer gift."
There's no formal loyalty program with points or tiers — it's all relationship-based through your individual rep. I'd estimate the informal perks have saved me about $150-200 over the 10 orders. Not life-changing but appreciated.
My advice: be a good customer — pay promptly, communicate clearly, don't make frivolous complaints — and the reps will take care of you over time. It's a relationship business at the end of the day.

This is the kind of long-term review that gives new buyers like me confidence. One question: looking back over 10 orders, is there anything you'd do differently?
