Power Peptides recently released a new batch of oils at super cheap pricing, so naturally I wanted to see what was actually in the vial. Instead of taking the label at face value, I sent one out for an independent blind test.

The lab was not told what compound or concentration the vial was supposed to contain — it was submitted simply as an unidentified sample.

Label claim: Masteron Propionate — 100 mg/mL
Lab identified: Drostanolone Propionate ✅
Measured concentration: 109.32 mg/mL --

That means this particular sample tested at roughly 109% of the label claim, coming in about 9.3% over the stated concentration.

Considering how inexpensive Power Peptides priced this recent release, I was especially interested in seeing whether the numbers would actually back it up. For the vial I submitted, the lab independently identified the correct compound and measured it slightly above the advertised concentration.
