How I verify my compounded peptide — March 2026

Current GGPeps sema pricing: - 5mg vial: $34 - 10mg vial: $58 - 3-pack 5mg: $92 ($30.67/vial) - 5-pack 5mg: $145 ($29/vial) At the 5-pack price of $29/vial for 5mg, if you're doing 1mg/week that's $5.80/week or ~$25/month. Versus $1,350/month for retail Ozempic without insurance. The math speaks for itself. And yes, based on my testing, GGPeps sema slightly edges QSC on average purity (96.4% vs community average ~95.8% for QSC sema). Small difference but it's there. 📊

I switched from QSC sema to GGPeps sema about 4 months ago. Anecdotally, I felt like the GGPeps sema worked slightly better at the same dose — more appetite suppression, more consistent effect throughout the week. Could be placebo, could be the purity difference, could be batch variation. Hard to say without controlled testing. What I CAN say objectively is that GGPeps sema dissolves faster and clearer during reconstitution. My QSC sema sometimes took 2-3 minutes of swirling to fully dissolve and occasionally had a very slight haze. GGPeps dissolves in under a minute and is always crystal clear. Small thing but I noticed it.

Sara, the dissolution difference is interesting. Faster/cleaner dissolution can indicate better lyophilization process — the powder is more porous and has more surface area for the solvent to penetrate. It doesn't necessarily mean higher purity but it does suggest more refined manufacturing. I'll be doing another round of testing in April with fresh batches from both GGPeps and QSC, tested at both PeptideMeter and Janoshik simultaneously. That should give us the most apples-to-apples comparison possible. Will post a dedicated thread with results. Stay tuned. 🔬
