Bottom line
Platinum Lion Peptides combines low prices, solid third-party testing and a longer track record than most vendors we review. The store is closed to visitors without an account. The product is called “GLP-3(R)” and has no description, so buyers must rely on the COAs, which identify it as retatrutide.
Products and pricing
GLP-3(R) is listed in stock at:
- 10 mg: $59.99 ($6.00/mg)
- 20 mg: $119.99 ($6.00/mg)
- 30 mg: $149.99 ($5.00/mg)
- 60 mg: $219.99 ($3.67/mg)
A GLP-3(R)/cagrilintide blend is also sold.
Testing
The certificates page links a COA for each size:
- 10 mg, lot RT10-1005 (ILS Laboratories, July 28, 2026): 99.75%, 10.34 mg, identity “Retatrutide Confirmed”. Sterility (PCR) showed no growth, endotoxin was reported at 0.084 EU/mL and heavy metals were not detected.
- 30 mg, lot RT30-1007 (ILS, June 23, 2026): 99.89%, 31.45 mg, with heavy metals not detected and sterility passed.
- 60 mg, lot RT60-1001 (MDx BioAnalytical Laboratory, February 19, 2026): 99.78%, 61.97 mg by mass identification, endotoxin pass.
ILS identifies the peptide by HPLC retention time against a reference standard, not by mass spectrometry.
