[REVIEW] GGPeps — looking for input

This catalog guide is exactly what I needed. Quick question about the tirzepatide 10mg vs 30mg vials — is there any quality difference or is it literally the same peptide at different fill amounts? I'm starting at 2.5mg/week so the 10mg vials make more sense economically (4 weeks per vial at $18 vs 12 weeks per vial at $42). But if the 30mg vials are somehow better quality I'd rather go that route.

e peptide, same quality, different fill amount. The 10mg vials are great for lower doses. Your math is right — at 2.5mg/week: - 10mg vial lasts 4 weeks = $4.50/week - 30mg vial lasts 12 weeks = $3.50/week The 30mg is slightly cheaper per-mg but you're committing to using one vial for 12 weeks. Reconstituted peptide is generally good for 6-8 weeks refrigerated, so at 2.5mg/week from a 30mg vial you're pushing the stability window. My recommendation for 2.5mg/week: Start with 10mg vials. Once you titrate up to 5mg+ where you'll use a 30mg vial in 6 weeks, switch to the larger vials for better economics. 👍

Nice guide. One addition: GGPeps recently added cagrilintide to their catalog (the amylin analog that Novo Nordisk is pairing with semaglutide in the CagriSema trials). $52 for a 5mg vial. Very few community tests exist — I've only seen one at 93.8% purity — but the fact that they're offering cutting-edge peptides is impressive. Not recommending it yet (too new, too little data) but it's worth watching. If CagriSema gets FDA approval, standalone cagrilintide could become a hot item. 🔬

Good add anders_CPH. Cagrilintide is fascinating but way too early to recommend. I'd put it firmly in the "wait and watch" category. Let the early adopters test it and build a data pool before committing your money. Alright folks, I'll update this catalog guide quarterly as GGPeps adds products and as more testing data comes in. Stay informed, stay safe, and always verify what you're putting in your body. This community is at its best when we share data openly. 🙏

Been lurking for months and this thread finally convinced me to create an account. Just placed my first GGPeps order: 2x tirz 30mg + reconstitution kit. $106 total. Paid with CashApp, got confirmation in 20 minutes. This forum is an incredible resource. The combination of purity data, vendor comparisons, and practical dosing advice has given me more confidence than any doctor's office visit about compounded peptides. Thank you all for being so thorough and transparent. Starting my peptide journey next week! 🎉
