How to properly dose S4... The Dylan Gemelli Method

Thank you for posting this protocol Dylan. We have seen you discuss this over the years and absolutely love your protocol as well as your Punch Out references! =)
LOL its the greatest video game of all time so any time i get the chance to incorporate it, i will! LOL
 
Good breakdown on the split dosing. The 5/2 on/off protocol specifically for managing the vision side is worth highlighting for anyone new to S4 — the yellow tint and night vision impairment are dose-dependent and reversible, but the cycling approach definitely reduces the cumulative impact on the photoreceptor binding.

One thing worth pairing with an S4 cycle from a recovery standpoint: BPC-157 sub-Q has shown some data on NO pathway support which indirectly benefits vascular function — relevant given S4's androgenic activity in certain tissues. Not a direct counter to the visual side specifically, but supports overall tissue homeostasis during a cycle.

On dosing precision: when working with liquid research compounds generally, consistent measurement is critical. A 1mg variance in a 25–50mg daily dose of S4 represents 2-4% error, which over an 8-week cycle compounds into meaningful inconsistency in exposure. Digital precision scales or accurately calibrated syringes matter more than people realize.

The 5-week on/2-week off structure that Dylan recommends is also solid for giving the androgen receptors in ocular tissue time to clear. Some people extend to 6/2 without issues but sticking to 5/2 is the more conservative documented approach.
