MOTS-C Giving You Itchy Welts? Here Is How to Fix the Reaction

Its pretty common people get a reaction when they pin MOTS-C. Itchy, welts popping up, that uncomfortable almost allergic feeling at the injection site. If this has happened to you, you are not alone and you do not have to give up on the compound just because of this.

From my experience here is what helps the Antihistamine solution actually worked for me personally after all the other options didn't one time.

Dilute it more

If you mixed your vial with 2mL of BAC water try doubling that next time. More diluted solution goes in gentler and cuts the reaction down for a lot of people.

Let it warm up first

Pull it out the fridge and let it sit until it is close to room temp before you pin. Cold solution straight out the fridge seems to trigger more irritation for a lot of people.

Go slow

Do not rush the shot. Push it in slow over a few seconds instead of blasting it in fast. Makes a real difference.

Rotate your spots

Hitting the same spot over and over builds up irritation. Spread it around and give each site time to chill before going back to it.

Try IM instead of SubQ

Some people who react bad with SubQ do fine going intramuscular instead. Worth testing if the other stuff is not working.

Antihistamine — last resort only

If nothing else gets it under control a simple antihistamine before your shot can take the edge off. This is the last thing to try not the first.

Most people dealing with this do not have a real allergy. It is usually one of these things and fixing it solves the problem completely.

Anyone else run into this and found what worked for you?
