Hitting the Needle: Tesamorelin Injection Site Reactions & Bloodwork

Posted by greg208 in Safety & Side Effects - 1 points, 3 comments.

I started the 2 mg daily Tesamorelin injection around three months ago to tackle my visceral fat build‑up after a tough stint in the fire service. Within the first week I noticed a red, itchy spot at the injection site that stayed inflamed for a couple of days after each jab. I tried rotating the leg, using a smaller needle, and icing the area – all of which helped reduce the swelling but didn’t stop it entirely.

The itching got worse on my second week and I started using a mild hydrocortisone cream, which seemed to calm it down. 5 mmol/L on a fasting test – I’d never had that high before. 8 %.

I stopped taking the supplement for a week and the glucose dropped back into the normal range. Iੰਜ. I’m not making any wild claims but it made me realise Oscamole could affect glucose and that injection site irritation can be persistent. If you’re on Tesamorelin, keep an eye on your blood sugars and consider rotating sites and maybe a topical steroid if the redness won’t subside.

• kayla_s: I’ve been on a daily injection for a growth hormone analogue for about six months, and the same itch‑redness stuck with me at first. I switched to a 27‑gauge needle and always let the muscle sit for 15 minutes after injection before applying any cream. I wasn’t using steroids, just a thin layer of fragrance‑free moisturizing lotion, but the flare still came back after a few days. When my fasting glucose spiked, I paused the dose and the numbers went back down, so I agree on the glucose check. D
• greg208: I’m just keeping it to glucose for now – insulin’s a later probe if the glucose swings keep popping up. The redness on my own legvious side usually hits peaks and subsides after about 3‑4 days, even after the 28‑gauge needle and 10‑minute sit‑down I’ve been using. I still apply a thin layer of fragrance‑free lotion right after the injection, then let it sit until it’s pretty dry before the cream. I’ll start checking fasting insulin next month if the glucose stays high again. Looking forward to
• greg208: I usually just keep an eye on fasting glucose; insulin’s a bit trickier unless you’re doing a full panel. The redness on my site usually subsides within 48‑72 hrs once you stop injecting into the same area. If it lingers longer it’s worth trying a new site or a slightly lower dose for a week.
