A bodybuilder friend of mine said his coach told him that almost all gear that advertised higher than 200 mg/mL was bogus. I was about to buy a test blend that advertised 400 mg/mL. I don’t care about the blended esters, but I like higher concentration because I pin Sub-q and want to keep the volume of injections low. I don’t care so much about PIP either. That had me wondering about the science. For example, I’ve heard that primobolan starts lose its integrity around 200 mg/mL. I was also thinking of buying some primo advertised as 175 mg/mL. So what do you think? Do you prefer to buy the lesser-concentrated gear?
Your friends coach is a moron.
LOL. Okay, guess that’s a vote for the higher concentrated gear being as likely to be legit as the lower.
Looks like it’s been discussed on here before, but with no definitive conclusion.

That’s not saying I would use it. I tried 400mg/ml one shot and will never use again. Way too much solvent. Had a huge welt for over a week.
If I buy it, I will draw it in the same syringe with my 200 mg/mL pharmacy test cyp. Hopefully, that will help a bit.
Technically, “solute” is dissolved in the “solvent” to make a “solution.”
As a chemist, you are both correct.
High concentration compounds rely on industrial solvents to increase the solubility over what the oil would normally accept. Benzyl Benzoate is usually the driver and because it’s not naturally occurring it can lead to injection soreness and overall inflammation.
As a loose rule, Test, deca and eq cannot carry north of 300 mg/ml without the BB.
Primo is generally thought to cap out at 200 with the BB.
All of that also depends on the specific carrier oil used, hence the loose rule qualifier.

Thank you EFShadow! That was a satisfying answer that makes sense of all the non-chemist subjective experiences/opinions I’ve read.
Also means that a little irritation from say a T-400 injection probably means they at least tried to use a solvent to increase the solubility of the oil.

Yes Sir.
Nah I’d say you have an equal chance of 200mg/mL UGL being underdosed (or wrongly doses) and you do 400mg/mL. The higher stuff just needs more BA/BB and can hurt like a MF after injection.

That seems to be the answer. I’m realizing it’s a good sign if it hurts at the higher concentrations.
