Starting GHK-cu tomorrow, how does this sound?

Summary

What dosage schedule and timing should a first-time user follow for GHK-Cu injections?

The original poster outlines a cautious ramp-up from 1 mg to 2 mg daily for six weeks followed by a month off. Several users report going straight to 2 mg at bedtime for 6-8 weeks without cycling. Others note injection-site pain that may lessen over time and suggest drawing extra bac water or adding zinc to reduce sting. A dosage-calculation mix-up is corrected in the thread.

What this discussion establishesWhere people disagree

Whether to cycle off after six weeks or stay on continuously

Nothing here is advice.

Everyone, I'm beginning my GHK-cu regimen starting tomorrow. I'll begin with a low dose of 1mg injected in the morning for the first week. Then increase to 2mg in the morning the following week. Plan is to continue at 2mg each day for six weeks followed by a four-week break. Is this a sensible approach for someone new to it? Would appreciate any tips from those with experience.

That plan looks fine. I jumped right in at 2mg each night before sleep and kept it going for six to eight weeks before stopping.

How many milligrams is your GHK? How much BAC water did you mix in?

Standard 50mg vial. I put in 2.5ml of BAC so five units gives 1mg.

Thanks. Still deciding between morning and evening shots. What made you choose right before bed?

I also do it at bedtime. Partly because I'm using Glow and recovery happens more overnight. Expect some post-injection pain. You can draw a few extra units of BAC first to cut the burn. Some people add zinc since copper seems to cause the sting. There are older threads here with more details on that. For me the sharp feeling turned into an itch after a couple weeks and I just lived with it.

I began at 2mg and have kept going without any breaks. Started four months ago.

Not sure if this is a US thing or simple math. With 50mg in 2.5ml BAC, wouldn't five units be half a milliliter, which is one-fifth of the total and therefore 10mg instead of 1mg? Or am I missing something?

Or was that just a test and I fell for it?

Talking to myself here. Realized the 5 on the syringe means the 50-unit line, so it's actually 0.5ml. Going back to sleep.

Maybe this will help.

No special reason, it just fit easily into the bedtime routine.

Thanks, yes I meant the 5 marking the 50 line. And I'm an accountant.
